Fig. 2From: Comparative analysis of taxonomic, functional, and metabolic patterns of microbiomes from 14 full-scale biogas reactors by metagenomic sequencing and radioisotopic analysisAverage values of relative abundances of major categories of functional genes in the shotgun metagenomes obtained from manure-based and sludge-based samples. The black square indicate those categories with significantly different relative abundances in manure-based and sludge-based samplesBack to article page
