Aromatic compound-degrading taxa in an anoxic coal seam microbiome from the Surat Basin, Australia.

摘要: Methane is an important energy resource internationally, and a large proportion of this methane produced by microbial communities living in coal seams. Despite the value for human security, our understanding metabolic roles played specific taxa during biodegradation to situ quite limited. In order develop greater catabolism on coal, community from seam Surat Basin, Australia, was incubated 10 different aromatic organic compounds: coronene, benzo[a]pyrene, pyrene, phenanthrene, naphthalene, ethylbenzene, phenol, benzoate, vanillate syringate. Each these compounds either occurs or possible product process. 16S rRNA sequencing revealed substantial changes each response carbon substrate provided. Abundant substrate-specific were identified their probable catabolic proposed based literature searches related taxa. This study first link substrates available environments. Two conceptual models putative degradation pathways key responsible are proposed.
