“…Thus the conversion of lactic acid to acetic acid may reduce the antibacterial activity. In consideration of lactic acid, but not acetic acid, played the major role in the growth inhibition of enterobacteria 32 , 35 , the homofermentative LAB was also necessary for silages. Therefore, for development of functional bacterial inoculants, both of selected homofermentative and heterofermentative LAB should be involved, and the rate of them should be regulated based on the lactic acid and acetic acid production, so as to inhibition the growth of undesirable bacteria, as well as yeasts and fungi.…”

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 before day 20 and then the dominance was shifted to Lb. parafarraginis until the late stage of ensiling. In contrast, the epiphytic Lactococcus lactic and Lb. plantarum played major roles at the beginning of naturally fermented silages and then Lb. plantarum and Lb. brevis were the most abundant at the later stage. In conclusion, these two selected strains had capability of improving the silage quality and providing the reproducible ensiling process, thus having the potential as silage inoculants.

The fate of verocytotoxigenicEscherichia coliC600φ3538(Δvtx₂::cat) and its vtx₂prophage during grass silage preparation

Abstract: These studies suggest that the ensiling of grass may create an environment which facilitates the emergence of new verocytotoxigenic E. coli.
