Table 4 General overview on the metagenomic and hydrolytic potential of the analyzed biogas microbial community in relation to two other studies

From: Deep metagenome and metatranscriptome analyses of microbial communities affiliated with an industrial biogas fermenter, a cow rumen, and elephant feces reveal major differences in carbohydrate hydrolysis strategies
