The impact of Lactobacillus plantarum TUA1490L supernatant on in vitro rumen methanogenesis and fermentation

This study investigated the suppression of in vitro rumen methane (CH4) output by the supernatant of Lactobacillus plantarum TUA1490L. Hydrogen peroxide (H2O2) was detected in the supernatant. Although CH4 output was reduced by 72%, the supernatant had an adverse effect on total volatile fatty acid (VFA) concentration.
