The invention discloses nitrobacter winogradsky and nitrobacteria-denitrifying bacteria complex microbial inoculants, a production method and application. Nitrobacter winogradsky is deposited at the China Center for Type Culture Collection with the accession number of ((i) Nitrobacter Winogradsky i ( / i)) Y3-2, CCTCC NO: M2014203. The nitrobacter winogradsky has a function of effectively treating nitrite, and is mixed with nitrosomonas europaea and pseudomonas stutzeri to obtain the complex microbial inoculants, and the complex microbial inoculants can efficiently remove nitrogen in water, and can be used for treating aquaculture water, livestock breeding sewage or industrial sewage.

Provided is a method for removing, during a step for producing a sugar solution, a fermentation inhibiting substance, which is generated during a step for producing sugar from a cellulose-containing biomass. Also provided is a method for steadily generating a pure sugar solution, which has an extremely low content of a fermentation inhibiting substance, over a long period of time. Specifically, disclosed is a method for producing a pure sugar solution, which uses a cellulose-containing biomass as the starting material and which involves: a step (1) for producing a sugar solution by subjecting a cellulose-containing biomass to decomposition treatment; a step (2) for subjecting the sugar solution obtained in step (1) to coagulation treatment; a step (3) for filtering the sugar solution obtained in step (2) by means of a microfiltration membrane and / or an ultra-filtration membrane, and for collecting the sugar solution from the permeate side; and a step (4) for filtering the sugar solution obtained in step (3) by means of a nano-filtration membrane and / or a reverse osmosis membrane, for collecting the pure sugar solution from the non-permeate side, and for removing a fermentation inhibiting substance from the permeate side.

Disclosed is a method for producing an aqueous refined sugar solution, in which a biomass residue produced in a step of producing a sugar from a cellulose-containing biomass is removed in a step of producing an aqueous sugar solution, thereby preventing the clogging of a microfiltration membrane and / or an ultrafiltration membrane and producing the aqueous refined sugar solution steadily for a long period. Specifically disclosed is a process for producing an aqueous refined sugar solution using a cellulose-containing biomass as a raw material, which comprises the steps of: (1) decomposing the cellulose-containing biomass to produce an aqueous sugar solution; (2) causing the aggregation in the aqueous sugar solution produced in step (1) with an aggregating agent to produce an aqueous sugar solution having an average particle diameter of 2 [mu]m or more as measured by a particle size distribution method; and (3) allowing the aqueous sugar solution produced in step (2) to pass through a microfiltration membrane and / or an ultrafiltration membrane to filtrate the aqueous sugar solution and collecting an aqueous sugar solution from the permeated side of the microfiltration membrane and / or an ultrafiltration membrane.

The invention relates to an alcohol and succinic acid production method by fermenting cellulosic raw material. Cellulosic raw material is pulverized, and low-concentration alkali solution is added for pre-treatment; cellulase and xylanase are performed with enzymolysis, and an enzymolysis product is filtered and concentrated to obtain concentrating sugar liquor; in an alcohol fermenting system, the concentrating sugar liquor is used for fermenting and producing alcohol; in a succinic acid fermenting system, the concentrating sugar liquor is used for fermenting and producing succinic acid; gasproduced in the alcohol fermenting process is led into a succinic acid fermenting and producing system after degerming, filtering and washing. The invention ensures that a great quantity of cellulosic waste produced in farming and forestry production can be effectively utilized, solves the problem that carbon dioxide auxiliary material is additionally added during succinic acid fermentation, lowers greenhouse gas discharge value during alcohol fermentation and cost for treating tail gas, has the advantages of wide raw material resource, low production cost, high production efficiency and the like, is favourable for energy saving, emission reduction and environment protection, and is favourable for popularizing and applying.

The invention discloses a jewel orchid fruit vinegar, which is prepared according to the following steps: 1kg of jewel orchids, 3kg to 5kg of oriental wormwood, 3kg to 5kg of kudzu vine roots, 3kg to 5kg of liquorice and 1kg to 2kg of haws are adopted and washed with water; the materials are decocted for three times; the decoction is clarified to obtain liquor, and after alcoholic fermentation, acetic fermentation, aging, filtration, stabilization and ultrafiltration, the jewel orchid fruit vinegar is obtained. The invention also discloses a jewel orchid fruit vinegar beverage, the jewel orchid fruit vinegar, water, high fructose corn syrup, glucose, rock candy and honey are proportioned, boiled and uniformly blended, and thereby the jewel orchid fruit vinegar beverage is obtained. Both the inherent ingredients and the nutritional values of the jewel orchid fruit vinegar and the jewel orchid fruit vinegar beverage produced by the invention are better than the inherent ingredients and nutritional value of table vinegar with grain as material, the jewel orchid fruit vinegar and the jewel orchid fruit vinegar beverage keep the unique taste of the jewel orchid as a traditional Chinesemedicine, are acid, soft and rich in nutrition, and have certain stomach-strengthening, digestion-promoting, tonifying and health-care effects, the quality and the grade are high, and moreover, sincealcoholic fermentation and acetic fermentation are carried out in one step, the production period is shortened.
