materials and methods phe degrading bacteria were isolated from surface sediments. isolated strains were then identified by biochemical and molecular (16s rdna gene sequence) analysis. rsm was employed to evaluate the optimum biodegradation of phe by the most effective isolated strain. the investigated parameters included the temperature, inoculum sizes, ph, nh4cl concentration, and salinity. o...

biodegradation of polycyclic aromatic hydrocarbons, toxic compounds widely distributed in the environment by bacteria, is a cheap and safe cleaning up method. the present study attempts to isolate and characterize dioxygenase-producing bacteria which are able to degrade phenanthrene and pyrene from refinery soils. it also aims to assess in vitro biodegradation. to do so, two contaminated soil s...

in this study, among the 21 diesel-degrading bacteria that were isolated from an oil-polluted area in fars (iran), 6 bacterial strains were tested for their capability to metabolize and grow on diesel oil by degrading its hydrocarbons content. the biochemical characteristics and 16s rrna sequence analysis of diesel-degrading bacteria showed that these strains were related to the genus pseudomon...
