Functional potential of the biofilm-forming microbes as revealed by analysis of 479 microbial genomes. a Biosynthetic gene clusters found on the 479 genomes recovered from 101 biofilm metagenomes. Putative product types were assigned by antiSMASH. b Number of CRISPR arrays identified from biofilm-derived genomes. c CRISPR arrays reconstructed from two cyanobacterial genomes and two acidobacterial genomes. White boxes indicate repeats and diamonds indicate spacers. Conserved T, C, and G nucleotides are displayed in yellow, green, and pink, respectively. The putative CRISPR-associated genes are shown with different colors, most of which are RNases. RAMP repeat associated mysterious protein
