Abstract
The invention belongs to the field of bioengineering, and particularly relates to a method for producing alcohol with basic material being chitin. The method comprises key production links and implementation ways. The chitin can be directly fermented into alcohol after being degraded into water-soluble chitosan oligosaccharide. Due to the fact that chitin has huge reserves and is low in cost, the chitin can partially replace petroleum when used as a raw material for producing alcohol, the energy crisis is relieved, consumption of corn and the like is reduced, alcohol products can also be produced, and the technology has the great significance.
Description
Technical field
This technological invention belongs to bioengineering field, is specially the technology of a raw material production alcohol based on chitin.
Background technology
Chitin is very abundant at occurring in nature storage, take 2-acetylamino-2-deoxy-D-glucose as basic composition unit, current is that the product of raw material production is based on degradation material, medicine or healthcare products with chitin, as suture line, bandage, timbering material, Glucosamine Sulphate, glucosamine hydrochloride etc., based on chitin, raw material production alcohol and related products not yet have report.The method of producing alcohol conventional is ethylene synthase, consumes a large amount of oil; Or obtain with fermentations such as starch, sucrose, glucose, consume a large amount of grain; Or raw material production alcohol based on Mierocrystalline cellulose, but a lot of sport technique segment is not yet broken through, and efficiency is low; So, based on chitin, raw material production alcohol is a very promising approach.Chitin obtains chitosan after physics, chemistry or biological enzyme process take off acetyl, and chitosan obtains chitosan oligomer after peroxide decomposition or bio-enzyme degradation, and correlation technique is comparative maturity, and defines product.
Summary of the invention
The present invention is a kind of technology of raw material production alcohol based on chitin, is different from the production method of raw material based on starch, sugar or Mierocrystalline cellulose etc.The approach realizing this technology is:
Chitin → chitosan → chitosan oligomer → alcohol
Chitinous source can be natural shrimp and crab shells, or containing the microorganism etc. that chitin enriches.
The first step, chitin takes off acetyl through chemistry, physics or biological enzyme process and obtains chitosan, correlation technique comparative maturity, but the chitosan polymerization degree is high, and can not be produced alcohol by direct fermentation, individual is proven by experiment.
Second step, becomes chitosan oligomer (about 3000Da) degradation of chitosan, and can use water dissolution, can adopt the method such as oxygenolysis, bio-enzyme degradation, correlation technique is comparative maturity also.
3rd step, oligopolymerization chitosan sugar-fermenting generates alcohol, and not having relevant report at present, is sport technique segment of the present invention, and chitosan oligomer direct fermentation is generated alcohol, and I proves this technical feasibility through many experiments, and fermenting speed is fast.
specific experiment method:
Reagent: purchase the chitosan oligomer in bulk from Qinhuangdao Le Yu Science and Technology Ltd.; The Japan of Shanghai Yi Ka Bioisystech Co., Ltd packing produces chitosan oligomer (water-soluble).
Condition: add reagent in bottle, by water dissolution, is no more than capacity 1/3, concentration 10.0%, Angel Yeast 1.0%, temperature 30 DEG C, time 72h, sealing anaerobically fermenting, and does control sucrose fermentation test simultaneously, and condition is identical.
Result: the bubble that fermentation produces can be observed in centre, directly can smell the alcohol smell that fermentation produces after fermentation ends, ethanol concn is about 3.0%vol, similar with control sucrose.
Main technologies of the present invention produces alcohol with chitosan oligomer direct fermentation.Along with the maturation of technology, can be applied to production alcohol, part replaces gasoline, saves food and the energy, or produces other products alcoholic, as drinks, very meaningful.The protection domain that raw material production alcohol or alcoholic product are this patent based on chitin, concrete protection domain is defined by appending claims.
Claims (2)
1. raw material production alcohol based on chitin.
2. be that supplementary material produces drinks with chitin.
