Red seaweed supplementation suppresses methanogenesis in the rumen, revealing potentially advantageous traits among hydrogenotrophic bacteria
Comparative genomic analysis between the Duodenibacillus sp. and other hydrogenotrophic rumen organisms revealed metabolic traits that may provide Duodenibacillus sp. with a competitive advantage in H<sub>2</sub> scavenging. Our findings provide an initial understanding of how the rumen microbiome responds to a promising CH<sub>4</sub> reducing feed additive and serve as a model for alternative stable rumen microbiome states that produce less methane and increase animal productivity. Ultimately, insights from the work presented here might enable the development of advanced microbiome-based strategies to reduce enteric methane production.
