Procedure

The fermentation medium is a silvergrass hydrolysate pretreated by dilute acid. For pretreatment, the concentration of the dilute acid is 1-4%, the operation temperature is 130° C., and the reaction time is 15 min at this temperature. In this case, NaOH is added to adjust the pH value of the hydrolysate to be 6.0, the fermentation temperature is controlled at 30° C., the agitation of the incubator is maintained at 100 rpm, and the ratio of the inocula size of the culture and the volume of the fermentation medium is 1:6 (v/v). The content of xylose in the silvergrass hydrolysate is 17.5-23.14 g/L, the content of the inhibitor furfural is 0.17-0.67 g/L, the amount of xylitol produced is 5.59-6.13 g/L, and the overall utilization of xylose is 97%, as shown in Table 3.
