Correlation between microbial taxa relative abundance and metabolites (formate, acetate, propionate, butyrate, and lactate) concentrations (A) and inter-species co-occurrence (B). The minimal prevalence (among the sequenced samples) of one given microbial taxa was set to 30%. Species with a mean relative abundance >1.5% were chosen for co-occurrence analysis, and Spearman's rank correlation coefficient of > 0.7 is shown in the chord diagram
