Biodegradation of fluoranthene by Paenibacillus sp. strain PRNK-6: a pathway for complete mineralization.

abstract：:RpoS, the alternative sigma factor sigma(s), is important for bacterial survival under extreme conditions. Many enterobacteria are opportunistic human pathogens and their ability to survive in a changing environment could be an essential step for their virulence. To determine the presence of this gene in enteric bacte...
