[0036] definition

[0037] As used herein, the article "a" refers to one as well as more than one and does not necessarily limit its referent noun to the grammatical category of the singular.

[0038] As used herein, the terms "about" and "for or approximately" when used to modify an amount or value refer to an approximate amount or value that is greater or less than the exact amount or value recited in the claims or described herein. The exact value of the approximate value is determined by those skilled in the art recognizing the appropriate approximation of the exact value. As used herein, the terms convey that similar values not precisely recited in the claims or described herein can produce the same results or effects as those values recited in the claims or described herein, for which results or effects one skilled in the art would recognize are acceptably obtained by similar values.

[0039] The terms "percent by volume," "volume percent," "volume %," and "volume / volume %" are used interchangeably herein. The volume percent of a solute in a solution can be determined using the formula: [(volume of solute) / (volume of solution)] x 100%.

[0040] The terms "weight percent," "weight percent (wt%)," and "weight-weight percent (% wt / wt)" are used interchangeably herein. Weight percent refers to the percentage of a material by mass when included in a composition, mixture, or solution.

[0041] As used herein, "weight average molecular weight" or "Mw" is calculated as Mw = ΣNiMi 2 / ΣNiMi; where Mi is the molecular weight of the chain and Ni is the number of chains of that molecular weight. Weight average molecular weight can be determined by techniques such as static light scattering, gas chromatography (GC), high performance liquid chromatography (HPLC), gel permeation chromatography (GPC), small angle neutron scattering, X-ray scattering, and sedimentation velocity.

[0042] As used herein, "number average molecular weight" or "Mn" refers to the statistical average molecular weight of all polymer chains in a sample. The number average molecular weight is calculated as Mn = ΣNiMi / ΣNi, where Mi is the molecular weight of the chain and Ni is the number of chains of that molecular weight. The number average molecular weight of a polymer can be determined by techniques such as gel permeation chromatography, viscometry via the Mark-Houwink equation, and colligative methods such as vapor pressure osmometry, end group determination, or proton NMR.

[0043] The terms "increased," "enhanced," and "improved" are used interchangeably herein. These terms can refer to, for example, an amount or activity that is at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 125%, 150%, 175%, or 200% (or any integer between 1% and 200%) greater than the amount or activity compared to the increased amount or activity.

[0044] The terms "poly alpha-1,3-glucan," "alpha-1,3-glucan polymer," and "glucan polymer" are used interchangeably herein. Poly alpha-1,3-glucan is a polymer comprising glucose monomer units linked together by glycosidic bonds, wherein at least about 50% of the glycosidic bonds are alpha-1,3-glycosidic bonds. Poly alpha-1,3-glucan is a type of polysaccharide. The structure of poly alpha-1,3-glucan can be shown as follows:

[0045]

[0046] Poly alpha-1,3-glucan useful for preparing the poly alpha-1,3-glucan ester compounds described herein can be prepared using chemical methods. Alternatively, it can be prepared by extracting it from various organisms that produce poly alpha-1,3-glucan, such as fungi. Alternatively, poly alpha-1,3-glucan can be enzymatically produced from sucrose using one or more glucosyltransferases (gtf) (e.g., gtfJ), such as described in U.S. Pat. No. 7,000,000 and U.S. Pat. Nos. 9,080,195 and 8,642,757 (all three patents incorporated herein by reference).

[0047] The terms "glucosyltransferase," "gtf enzyme," "gtf enzyme catalyst," "gtf," and "glucansucrase" are used interchangeably herein. The activity of the gtf enzyme herein catalyzes the reaction of a sucrose substrate to produce poly-α-1,3-glucan and fructose as products. Other products (byproducts) of the gtf reaction may include glucose (where glucose is hydrolyzed from the glucosyl-gtf enzyme intermediate complex), various soluble oligosaccharides (DP2-DP7), and leucrose (where the glucose of the glucosyl-gtf enzyme intermediate complex is linked to fructose). Leucrose is a disaccharide composed of glucose and fructose linked by an α-1,5 linkage. Wild-type forms of glucosyltransferases typically contain (from N-terminus to C-terminus) a signal peptide, a variable domain, a catalytic domain, and a glucan-binding domain. The gtf herein was classified under glycoside hydrolase family 70 (GH70) according to the CAZy (Carbohydrate Active Enzyme) database (Cantarel et al., Nucleic Acids Res. 37: D233-238, 2009).

[0048] The percentage of α-1,3 glycosidic bonds between glucose monomer units of the poly α-1,3-glucan used to prepare the poly α-1,3-glucan ester compounds described herein is at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% (or any integer value between 50% and 100%). Thus, in such embodiments, the poly α-1,3-glucan has less than about 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, 1%, or 0% (or any integer value between 0% and 50%) of non-α-1,3 glycosidic bonds.

[0049] The poly alpha-1,3-glucan used to prepare the poly alpha-1,3-glucan ester compounds described herein is preferably linear / unbranched. In certain embodiments, the poly alpha-1,3-glucan has no branch points or has less than about 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% branch points based on the percentage of glycosidic bonds in the polymer. Examples of branch points include α-1,6 branch points, such as those present in mutanoglucan polymers.

[0050] The terms "glycosidic linkage" and "glycosidic bond" are used interchangeably herein and refer to a type of covalent bond that connects a carbohydrate (sugar) molecule to another group, such as another carbohydrate. As used herein, the term "α-1,3-glycosidic bond" refers to a type of covalent bond that connects α-D-glucose molecules to each other through carbons 1 and 3 on adjacent α-D-glucose rings. This bond is shown in the poly α-1,3-glucan structure provided above. Herein, "α-D-glucose" is referred to as "glucose."

[0051] The terms "poly alpha-1,3-glucan ester compound," "poly alpha-1,3-glucan ester," and "poly alpha-1,3-glucan ester derivative" are used interchangeably herein. A poly alpha-1,3-glucan compound is represented by the following structure:

[0141] Provided that, if (a) is present, at least one other ester group (b), (c), (d) and / or (e) is present, and

[0142] The degree of substitution of the ester group modification is 0.001 to 3.

[0143] It may be preferred that the ester group modifications are independently selected from:

[0145] (b) an aryl ester group;

[0146] (c) acyl group , wherein a is independently 6-24; and

[0147] (d) any combination thereof.

[0148] It may be preferred that the ester group modification is a combination of the following:

[0149] (a) acetyl;

[0150] (b) an aryl ester group; and

[0151] (c) acyl group , wherein a is independently 6-24.

[0152] It may be preferred that the ester group modification of the poly α-1,3-glucan ester compound is a combination of the following:

[0153] (a) acetyl; and

[0154] (b) Aryl ester groups.

[0155] It may be preferred that the ester group modification of the poly α-1,3-glucan ester compound is a combination of the following:

[0156] (a) acetyl; and

[0157] (b) Benzoyl.

[0158] The degree of substitution of the ester group modification of the poly alpha-1,3-glucan ester compound is 0.001 to 3, preferably 0.005 to 2, more preferably 0.01 to 1, and most preferably 0.02 to 0.8.

[0159] It may be preferred that a is independently 9-16.

[0160] The poly alpha-1,3-glucan derivatives disclosed herein comprise a poly alpha-1,3-glucan backbone randomly substituted with ester modifications along the polysaccharide backbone, such that the polysaccharide backbone generally comprises unsubstituted and substituted α-D-glucose rings. In embodiments where branching is present, the α-D-glucose rings of the branches may also be randomly substituted with ester modification groups. As used herein, the term "randomly substituted" means that the substituents on the glucose rings in the randomly substituted polysaccharide occur in a non-repeating or random manner. That is, the substitution on a substituted glucose ring may be the same or different from the substitution on a second substituted glucose ring in the polysaccharide [i.e., the substituents (which may be the same or different) are located on different atoms in the glucose ring in the polysaccharide], such that the overall substitution pattern in the polymer is irregular. Furthermore, the substituted glucose rings occur randomly within the polysaccharide (i.e., there is no pattern between substituted and unsubstituted glucose rings within the polysaccharide).

[0161] Depending on the reaction conditions, the poly alpha-1,3-glucan ester compounds disclosed herein may also include a poly alpha-1,3-glucan backbone that is "non-randomly" substituted with ester modification groups along the polysaccharide backbone. Where branching is present, the α-D-glucose rings of the branches may contain disproportionately more substitution than the backbone glucose monomer units connected by α-1,3-glycosidic bonds. It is also possible that under certain reaction conditions, the modifications may be present in a block-like manner within the polysaccharide.

[0162] Depending on the reaction conditions, it is also possible that the glucose carbon positions 1, 2, 3, 4, and 6 of the poly alpha-1,3-glucan backbone are "disproportionately" substituted. For example, the -OH group at carbon position 6 is a primary hydroxyl group and can be present in an environment with less steric hindrance. This OH group can be more reactive under certain reaction conditions, and therefore, more substitution can occur at this position. Under other reaction conditions, the OH group at carbon position 1, 2, 3, or 4 may be more reactive.

[0163] Without wishing to be bound by theory, it is believed that as the degree of substitution decreases, there may be a higher chance of "disproportionate" and "non-random" substitution.

In some embodiments, the composition may further comprise each enzyme in an amount of from about 0.0001% to about 10% by weight, from about 0.001% to about 5% by weight, from about 0.001% to about 2% by weight, or from about 0.005% to about 0.5% by weight based on the total weight of the composition.

[0168] Cellulases can have endocellulase activity (EC 3.2.1.4), exocellulase activity (EC 3.2.1.91), or cellobiase activity (EC 3.2.1.21). A cellulase is an "active cellulase" that is active under conditions suitable for maintaining cellulase activity; determining such suitable conditions is within the skill of the art. In addition to being able to degrade cellulose, cellulases can also, in certain embodiments, degrade cellulose ether derivatives, such as carboxymethyl cellulose.

[0169] Cellulase can be derived from any microbial source, such as bacteria or fungi. Included are chemically modified cellulases or protein engineered mutant cellulases. Suitable cellulases include, for example, cellulases from Bacillus, Pseudomonas, Streptomyces, Trichoderma, Humicola, Fusarium, Thielavia, and Acremonium. As other examples, cellulases can be derived from Humicola insolens, Myceliophthora thermophile, Fusarium oxysporum, Trichoderma reesei, or a combination thereof. Cellulase, such as any of the foregoing, can be a mature form lacking an N-terminal signal peptide. Commercially available cellulases that can be used herein include CELLUSOFT ® 、CELLUCLEAN ® 、CELLUZYME ® and CAREZYME ® (Novozymes A / S); CLAZINASE ® and PURADAX ® HA and REVITALENZ ™ (DuPont Industrial Biosciences), BIOTOUCH ®(AB Enzymes); and KAC-500(B) ® (KaoCorporation).

[0170] Alternatively, the cellulase herein can be produced by any means known in the art, for example, the cellulase can be recombinantly produced in a heterologous expression system such as a microorganism or fungus heterologous expression system. Examples of heterologous expression systems include bacteria (e.g., Escherichia coli (E. coli), Bacillus (Bacillus)) and eukaryotic systems. Eukaryotic systems can employ, for example, yeast (e.g., Pichia, Saccharomyces) or fungi (e.g., Trichoderma such as T. reesei, Aspergillus such as A. niger) expression systems.

[0171] In certain embodiments, the cellulase may be thermostable. Cellulase thermostability refers to the ability of an enzyme to maintain activity after exposure to elevated temperatures (e.g., about 60°C-70°C) for a period of time (e.g., about 30 minutes-60 minutes). The thermostability of a cellulase can be measured by its half-life (t½) (given in minutes, hours, or days), during which half of the cellulase activity is lost under defined conditions.

[0172] In certain embodiments, the cellulase can be stable over a wide pH range (e.g., neutral or alkaline pH, such as a pH of about 7.0 to about 11.0). Under such pH conditions, the enzyme can remain stable for a predetermined period of time (e.g., at least about 15 minutes, 30 minutes, or 1 hour).

[0173] At least one, two or more cellulases may be included in the composition. The total amount of cellulases in the composition herein is generally an amount ("effective amount") suitable for the purpose of using the cellulase in the composition. For example, an effective amount of a cellulase intended to improve the feel and / or appearance of a cellulose-containing fabric is an amount that produces a measurable improvement in the feel of the fabric (for example, improving fabric smoothness and / or appearance, removing fiber pills and fibrils that tend to reduce the sharpness of the fabric appearance). For another example, an effective amount of a cellulase in a fabric stonewashing composition herein is an amount that will provide a desired effect (for example, producing a worn and faded appearance in a seam and on a fabric plate). The amount of the cellulase in the composition herein can also depend on, for example, the process parameters (for example, equipment, temperature, time, etc.) and the cellulase activity in which the composition is used. The effective concentration of the cellulase in the aqueous composition for treating the fabric can be easily determined by a technician. In fabric care processes, the cellulase can be present in the aqueous composition (e.g., wash liquor) with which fabrics are treated at a concentration of, for example, a minimum of about 0.01 ppm-0.1 ppm total cellulase protein, or about 0.1 ppb-10 ppb total cellulase protein (e.g., less than 1 ppm), to a maximum of about 100 ppm, 200 ppm, 500 ppm, 1000 ppm, 2000 ppm, 3000 ppm, 4000 ppm, or 5000 ppm total cellulase protein.

[0235] pass 1 H NMR (nuclear magnetic resonance spectroscopy) determination of glycosidic bonds in water-soluble oligosaccharide and polysaccharide products synthesized by glucosyltransferase GTF8117 and α-1,2-branching enzymes. Dissolve 6 to 8 mg of dry oligosaccharide / polysaccharide polymer in 0.7 mL of 1 mM DSS (4,4-dimethyl-4-silapentane-1-sulfonic acid; NMR reference standard) in D2O. Stir the sample overnight at ambient temperature. Transfer 525 μL of the clear, homogeneous solution to a 5 mm NMR tube. 2D NMR experiments 1 H, 13 The C homonuclear / heteronuclear software suite was used to identify AGU (anhydroglucose unit) bonds. Data were collected at 20°C and processed on a Bruker Avance III NMR spectrometer operating at 500 MHz or 600 MHz. The system was equipped with a proton-optimized helium-cooled cryoprobe.1 H NMR spectroscopy is used to quantify the glycosidic bond distribution and identify polysaccharide backbones, such as those that are predominantly α-1,6. The results reflect the ratio of the integrated intensity of the NMR resonance representing each bond type divided by the integrated intensity of the sum of all peaks representing glucose bonds, multiplied by 100.

[0236] Method for evaluating the whiteness properties of polymers

[0237] Whiteness maintenance (also referred to as whiteness maintenance) is the ability of a detergent to prevent white items from losing their whiteness when washing them in the presence of soil. When soil is removed from dirty fabrics and suspended in the wash water, these soils may be redeposited on the clothes, making them less white each time they are washed, and white clothes may become very dirty / grimy over time. An automatic small-sized washing machine with 5 tanks was used to evaluate the whiteness benefits of the disclosed polymers. The SBL2004 soil test bar supplied by WFK Testgewebe GmbH was used to simulate consumer soil levels (a mixture of body soil, food, dust, grass, etc.). On average, each SBL2004 bar was loaded with 8g of soil. White fabric samples from the following Table 2 purchased from WFK were used as whiteness tracers. Before the wash test, the L, a, and b values of all whiteness tracers were measured using a Konica Minolta CM-3610D spectrophotometer.

[0238] Table 2.

[0239]

[0240] Notice:

[0241] *WI(A) – Light Source A (indoor lighting)

[0242] **WI(D65) – Illuminant D65 (outdoor lighting)

[0243] Three wash cycles are required to complete the test:

[0244] Cycle 1: The required amount of base detergent was completely dissolved by mixing with 7.57 L of water (at a defined hardness) in each mini-washer tube. 3.5 SBL2004 bars (approximately 28 g soil) and 3 whiteness tracers of each fabric type (in-house replicates) were washed and rinsed in the mini-washer under defined conditions and then dried.

[0245] Cycle 2: The above whiteness tracer was washed again with a new set of SBL2004 sheets and dried. All other conditions remained the same as cycle 1.

[0246] Cycle 3: The above whiteness tracer was washed again with a new set of SBL2004 sheets and dried. All other conditions remained the same as cycle 1.

[0247] After cycle 3, all whiteness tracers were dried and then measured again using a Konica Minolta CM-3610D spectrophotometer. The whiteness index change (∆WI(CIE)) was calculated based on the L, a, and b measurements before and after washing.

[0248] ∆WI(CIE) = WI(CIE)(after washing) – WI(CIE)(before washing).

[0249] The mini-washer has 5 tanks and can test 5 products in one test. In a typical polymer whiteness performance test, one reference product containing a comparative polymer or no polymer is tested along with 4 products containing the polymer of the invention and the "∆WI relative to reference" is reported.

[0250] ∆WI(CIE) relative to reference = ∆WI(CIE)(product) - ∆WI(CIE)(reference)

[0251] Method for evaluating the cleaning benefits of polymers

[0252] An agitated detergent washing machine is used to evaluate the cleaning benefits of the polymers. Some examples of test stains suitable for this test are:

[0253] Standard grass, ex CFT

[0254] Standard clay, ex CFT

[0255] ASTM dust sebum, ex CFT

[0256] Highly sensitive sebum on polyester cotton, ex CFT

[0257] BBQ Bacon on Knitted Cotton (prepared using Ex Equest's BBQ Bacon)

[0258] Dyed bacon on knitted cotton (prepared using dyed bacon from ex Equest)

[0259] The commercially available DigiEye software was used to analyze the L, a, b values of the fabrics.

[0260] A stock solution of the polymer of the present invention was prepared in deionized water to deliver the desired dosage via 5 ml aliquots. To prepare 1 L of test solution, a 5 ml aliquot of the polymer stock solution and the desired amount of alkaline detergent were completely dissolved by mixing with water (at a defined hardness) in the drum of an agitated power washing machine. The wash temperature was 20°C.

[0261] The fabrics to be washed in the drum of each agitator washing machine consisted of 2 test stains each (2 internal replicates), approximately 3 g of WfK SBL 2004 soil pieces, and additional knitted cotton ballast to bring the total fabric weight to 60 g.

[0262] Once all fabrics were added to the drum of an agitated power washing machine containing the wash solution, the wash solution was agitated for 12 minutes. The wash solution was then drained, and the fabrics were rinsed twice for 5 minutes before being drained and spin-dried. The washed stains were dried in an airflow cabinet and then analyzed for L, a, and b values using commercially available DigiEye software.

[0263] This process was repeated three more times, resulting in a total of four external replicates.

[0264] The Soil Removal Index (SRI) is calculated from the L, a, and b values using the formula shown below. The higher the SRI, the better the soil removal effect.

[0265] SRI = 100*((∆E b – ∆E a ) / ∆E b ))

[0266] ∆E b = √((L c -L b ) 2 + (a c -a b ) 2 + (b c -b b ) 2 )

[0267] ∆E a = √((L c -L a ) 2 + (a c -a a ) 2 + (b c -b a ) 2 )

[0292] Biodegradation data

[0293] Biodegradation test methods

[0294] The biodegradability of polysaccharide derivatives was determined according to the OECD 301B Ready Biodegradability CO2 Emission Test Guideline. In this study, the test substance served as the sole carbon and energy source, and under aerobic conditions, the microorganisms metabolized the test substance, thereby producing CO2 or incorporating carbon into the biomass. The amount of CO2 produced by the test substance (corrected for CO2 emitted by a blank inoculum) was expressed as a percentage of the theoretical amount of CO2 (ThCO2) that would have been produced if the organic carbon in the test substance had been completely converted to CO2.
