FIG 2.

Major bacterial genera detected in the consortium. (A) Relative abundances (percent total number of bacterial amplicons) of the major OTUs when the consortium was grown on different hydrocarbon sources: diesel fuel (diesel-1 and -2; duplicates), 4-component NAPL (NAPL), n-hexadecane (HEX), phenanthrene (PHE), naphthalene (NAP), and toluene (TOL). Amplicons were detected by 16S rRNA gene amplicon sequencing. Bacterial genus of each OTU is shown in parentheses. (B) Number of metagenome reads mapped to the assembled full-length 16S rRNA genes of major bacterial genera in the consortium grown on diesel fuel.
