Antibiotics resistance genes (ARGs) detected in anaerobic digestion driving microbiome and their Spearman’s correlation with physicochemical parameters and dominant microbial community. (A) The heatmap illustrates the distribution of 45 ARGs belonged to 8 antibiotic classes and 16 types of mechanisms found across the four metagenomes. The red, blue, white color determine the number of mapped reads and the number also illustrate the same things. (B) Spearman’s correlation between physicochemical parameters and ARGs represents the plot. (C) The correlation analysis between physicochemical parameters and ARGs classes. (D) The correlation analysis between physicochemical parameters and ARGs mechanisms. The numbers display the Spearman’s correlation coefficient (r). Blue and red indicate positive and negative correlation, respectively. The color density, circle size, and numbers reflect the scale of correlation. *Significant level (*p < 0.05; **p < 0.01; ***p < 0.001).
