Study on the enhancement of corn stover fermentation bybioactive water

In order to explore the role of bioactive water in corn stover fermentation, the moisture content in corn stover fermentation was regulated by DW and bioactive water for this experiment, and the sensory comprehensive assessment, cellulose and hemicellulose degradation rates were analyzed. The results showed that the comprehensive score on the 5 d was higher than that on the 10 d from the sensory evaluation analysis, and the sterilized corn stover fermentation was superior to the unsterilized corn stover fermentation, with the total score of treat1 (sterilized stover + BW) and treat4 (sterilized stover + BW + MYB3) higher than the other treatment groups. For sterilized and unsterilized stover, the maximum cellulose and hemicellulose decomposition rates occurred in the four groups (sterilized / unsterilized stover + BW + MYB3) treated in 10 d, which were 39.38%, 45.25%, 32.25%, and 38.63%, respectively. It nearly doubled compared with the control (sterilized / unsterilized stover + DW). The results show that bioactive water could improve the decomposition rate of stover cellulose and hemicellulose, and it is of great significance to provide a new feasible method for the application of stover fermentation.
