Fig. 5From: The active microbial community more accurately reflects the anaerobic digestion process: 16S rRNA (gene) sequencing as a predictive toolCanonical correspondence analysis of the a archaeal and b bacterial community, including the DNA (red) and RNA (green) profiles of each sample at OTU level. PERMANOVA was carried out to evaluate the effect of operational parameters on community composition, and significant (P < 0.01) correlations are presented by the arrowsBack to article page
