Figure 3: Genes related to alkane oxidation in microcosms of differing biodiversity.

Gene abundance and taxonomic affiliation at the phylum level were determined using the KEGG Orthology and M5NR databases, respectively, from MG-RAST. Taxa with abundance <5% are presented as “Others.” C, control; D, diesel-spiked soil; DR, diesel-spiked soil and red clay; DP, diesel-spiked soil and processed red clay. (a) phylum (b) genus.
