  • Publication number: 20240011057
    Abstract: The present invention relates to a method of preparing xylitol by using a xylose secondary mother liquor through fermentation. In the method, fermentation treatment is performed on a mixed liquid of the xylose secondary mother liquor and a xylose concentrate, and the xylose secondary mother liquor is subsequently batch-fed instead of glucose in the fermentation process. Thus, a glucose content in the fermentation system is stabilized, and some xylose is provided at the same time. In this way, the use amount of glucose and costs are reduced, and the system xylose can be relatively stabilized, thus improving the entire conversion rate. In the present invention, adding the xylose secondary mother liquor by mixed fermentation and batch feeding and the like enables the contents of heterosaccharides such as arabinose and mannose in the fermentation system to be always within a range of metabolization by fermenting strains, facilitating subsequent purification and improving the xylitol purity.

  • Publication number: 20230295677
    Abstract: The present invention provides a method of improving a biomass high-solid enzymatic hydrolysis rate. By screening particle sizes of the biomass substrate, different water content controls are performed on coarse and fine particle biomass substrates and then an entire water content of the mixture of the coarse and fine particle biomass substrates is controlled to achieve a reduced initial viscosity of the enzymatic hydrolysis and improve liquefaction speed, and finally improve the biomass high-solid enzymatic hydrolysis rate. The enzymatic hydrolysis system of the present invention can be easily constructed with lower equipment requirements, lower energy consumption, higher enzymatic hydrolysis efficiency and simpler operation process, helping the industrial production and applications.
