Comamonadaceae OTU as a Remnant of an Ancient Microbial Community in Sulfidic Waters.

abstract：:Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants of the environment. But is their microbial degradation equally wide in distribution? We estimated the PAH degradation capacity of 13 soils ranging from pristine locations (total PAHs approximately 0.1 mg kg(-1)) to heavily polluted industrial sites (tot...
