where each of R1, R2, and R3 may be the same or different and is independently selected from H, alkyl, alkoxyl, aryl, acyl, allyl, pyridyl, —OH, alkenyl, aralkyl, cycloalkyl, and heterocyclic structure containing O, S, or N; (C) 0.01% (w/w) to 10% (w/w) of at least one hydroperoxide compound with at least one hydroperoxide groups attached to a tertiary carbon; (D) 5% (w/w) to 95% (w/w) of at least one finely divided filler; (E) 0% (w/w) to 25% (w/w) of one or more components selected from a solvent, a photoinitiator, a stabilizer, and/or an antimicrobial agent. One embodiment of the invention is a dental cementation or core buildup kit that has enhanced compatibility between the acidic primer/adhesive and the cement or core buildup material, and therefore enhanced adhesion to a tooth. The kit includes (I) an acidic primer/adhesive composition having a pH less than 4.5; and (II) a cement or core buildup material having the above described composition comprising components (A)-(E). Another embodiment of the invention is a method for adhering a prosthetic device to a tooth to restore the function and/or appearance of a diseased tooth. Another embodiment of the invention is a method of providing a temporary cement, crown and/or bridge, inlay, onlay, endodontic sealer, and/or an endodontic filling material, using the inventive composition.

The present invention relates to acid tolerant Leuconostoc mesenteroides with excellent mannitol productivity and the use thereof. The inventive lactic acid bacteria is useful as a food additive composition and a Kimchi starter. Kimchi prepared with the addition of the inventive lactic acid bacteria is maintained at a suitable ripening degree over an extended period of time than to the prior Kimchis, and has excellent sensory properties, including excellent refreshing taste, weak sour odor and a very soft quality of sour taste.

The invention provides lactobacillus paracasei SLP16 for producing polysaccharides, application of the lactobacillus paracasei SLP16 and a feed additive prepared from the lactobacillus paracasei SLP16, and relates to the technical field of feed additives. The lactobacillus paracasei SLP16 disclosed by the invention is Lactobacillus paracasei SLP16; the Latin name is Lactobacillus paracasei, the name of the preservation unit is Guangdong Microbial Culture Collection Center; the address is Floor 5, Building 59, No. 100 courtyard, Xianlie Middle Road, Guangzhou city; the preservation date is July 5, 2021; and the preservation number is GDMCCNo: 61769. The SLP16 disclosed by the invention is still stable after passage, can inhibit escherichia coli and staphylococcus aureus, has good cholate-resistant and acid-resistant effects, has cohesiveness, hydrophobicity and oxidation resistance, and also can generate exopolysaccharides.

The present invention relates to a novel process for purifying phycobiliproteins, in particular acid-pH-resistant phycobiliproteins, the resulting phycobiliproteins, and the uses thereof.

The invention belongs to the technical field of salmonella phages, and particularly relates to an acid-resistant phage isolate capable of specifically cracking salmonella and application of the acid-resistant phage isolate in sterilization and bacterium prevention. The invention mainly discloses salmonella pullorum phage SG4P1 with the preservation number of CCTCC NO: M2018765. The salmonella phage is a strong phage isolated from the nature, and toxicological experiments prove that the salmonella phage is safe and free of any side effect. The experiments find that the phage can tolerate extremely high acidity, and therefore, the salmonella phage can have a strong cracking effect on salmonella in the intestinal tract through gastric acid. The phage is expected to be developed into a biological bactericide for preventing and treating infection and pollution of the salmonella.

The invention discloses an acid-tolerant bacterium group and application thereof in treating Fenton acidic effluent, and relates to biological treatment of acidic wastewater. The acid-tolerant bacterium group is screened and obtained from activated sludge of a leather sewage treatment plant, and the acid-tolerant bacterium group is composed of Geotrichum cucujoidarum NS-2 and Phialemoniopsis curvata NS-3; the GeotrichumcucujoidarumNS-2 is saccharomycetes, a bacterial colony of the GeotrichumcucujoidarumNS-2 is hoary, the GeotrichumcucujoidarumNS-2 is closely adhered to a culture medium, and partialhyphaestretch into the culture medium; and the PhialemoniopsiscurvataNS-3 is mucedine, a bacterial colony of the PhialemoniopsiscurvataNS-3is hoary, and partial hyphae stretch into the culture medium. The acid-tolerant bacterium group is applied to advanced treatment in the Fenton acidic effluent.

The invention provides an acidified soil improver, which, at the premise of improving soil fertility, can adjust character of acidified soil so that the acidified soil is more suitable for the growthof crops, especially acid-tolerant crops; therefore, crop yield of the acidified soil is increased. The acidified soil improver can be used often to further improve characteristics of soil, invert acidification of the soil, and restore soil fertility.
