Complete equipment for producing xylitol and arabinose by directly utilizing microbiological fermentation method

Abstract

The invention belongs to the technical field of biological fermentation and discloses complete equipment for producing xylitol and arabinose by directly utilizing a microbiological fermentation method. Corncob hydrolysate is adopted as a starting material, a high-tolerance yeast is taken as a carrier, and culture transformation is carried out through a primary seed culture fermentation tank and a secondary seed culture fermentation tank; xylose is transformed into xylitol under the conditions that the temperature is 36 DEG C and the pressure is 0.02MPa; and meanwhile, mannose, galactose and glucose in the hydrolysate are transformed into a biological oxidation-reduction enzyme and only -CHO in the xylose is catalyzed and transformed into -CH3OH. Effective transformation is carried out on all components of the corncob hydrolysate, industrial technology upgrading is carried out on a traditional product process, the obtaining mode of a rare sugar product is changed, the utilization rate of hydrolyzed components of the corncob is greater than 95%, the energy consumption and water consumption of a single product are reduced, waste residues and wastewater are greatly reduced, the quality of the product is improved and the cost of the product is reduced.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a complete set of equipment for producing xylitol and arabinose directly by microbial fermentation. Background technique [0002] At present, the complete set of equipment for preparing xylitol and arabinose by biological fermentation is an industrial production line designed and developed based on the development of non-grain raw materials and the technical achievements of comprehensive utilization. With the huge changes in productivity brought about by the industrial revolution, petroleum and petroleum products are very important as the driving force for comprehensively supporting the industry. However, excessive dependence and use of this non-renewable resource will eventually cause resource shortage or even depletion. The development of petrochemical products cannot meet the mission of social development. A series of problems faced by human beings ...

AI Technical Summary

Problems solved by technology

[0010] In summary, the existing problems in the prior art are: traditional xylitol and arabinose preparation methods mainly use petroleum refining, which requires a large investment in the oxidation process, and the production cost is high; the traditional preparation method consumes too much energy. Large and excessive waste water is a serious threat to the sustainable development of the economy and the environment
