Physiological and molecular characterization of a microbial community established in unsaturated, petroleum-contaminated soil.

abstract：:High-throughput sequencing (HTS) surveys, among the most common approaches currently used in environmental microbiology, require reliable reference databases to be correctly interpreted. The EukRef Initiative (eukref.org) is a community effort to manually screen available small subunit (SSU) rRNA gene sequences and pr...
