Janthinobacterium affiliated OTUs clustered at 99% identity. (A) The percentage of the community relative abundance assigned to Janthinobacterium OTUs processed as above but with OTU clustering at 99% identity. The six OTUs present at a mean relative abundance >0.2% are named along with their CNR of each OTUs representative sequence obtained via BLAST searching of non-environmental sequences is provided as NCBI accession number, taxon name, and percent identity match. Thirty-one Janthinobacterium assigned OTUs individually present at a mean relative abundance <0.2% are shown individually but named as 99Janth-other. (B) Maximum likelihood phylogenetic tree of the six most abundant Janthinobacterium OTUs and their CNR, with the glacial Betaproteobacteria member Polaromonas as an out group over 144 positions aligned using MUSCLE.
