Effects of inoculants Lactobacillus brevis and Lactobacillus parafarraginis on the fermentation characteristics and microbial communities of corn stover silage.

ABSTRACT: To improve silage quality of crop forages, bacterial inoculants are often employed. In this study, Lactobacillus brevis SDMCC050297 and Lactobacillus parafarraginis SDMCC050300 were used as inoculants to corn stover in lab silos for ensiling. At the initial stage of ensiling, the pH value of the inoculated silages reduced more drastically, and the inoculated silages had higher lactic acid and acetic acid contents. After 20 days of ensiling, a reduction in lactic acid content coupled with an increase in acetic acid and 1,2-propanediol contents was observed in inoculated silages. Furthermore, both the amount of lactic acid bacteria and the abundance of order Lactobacillales in inoculated silages were higher than those of controls in the whole process. Meanwhile, Lb. brevis predominated befor
