Proteus and Serratia Strains Obtained from Oil-Polluted Water Hydrocarbon Biodegradation

Balkrishna Narkhede

Two indigenous hydrocarbon exercising bacteria strains, designated as TKZ and QGR were insulated in oil painting rich Niger Delta of Nigeria. Determination of the nucleotide sequence of the gene garbling 16S rRNA allowed TKZ and QGR to be linked as Proteus vulgaris and Serratia marcescens. Hydrocarbon declination eventuality of the strains was verified on hydrocarbon mineral mariners medium (1, v/ v) at 37 °C. Assessment of oil painting declination capability of the isolates was covered using gas chromatographic analysis (GC). The capability of the strains to use benzene, diesel, kerosene, and naphthalene was also studied. The results show minimal increase in optic consistence at 540 nm and total feasible counts was commensurable with drop in pH of the culture media. Chance declination in the culture medium showed that the two isolates displayed biodegradation effectiveness above 90 for kerosene [1]. The two bacterial strains also retain a plasmid of about9.1 kb size which is suspected to impact the bacterium’s hydrocarbon declination eventuality.
