Phylogenetic Analysis on 16S Ribosomal DNA of Pseudomonas Strains from Oil Polluted Soil

In the current study we report molecular analysis of two bacterial isolates from an oil-polluted soil sample taken from the surroundings of an oil extraction field near Pitesti. This study focuses on two strains designated SQ2a and, respectively, SQ2b, because of their similar behave but very different colonies morphology. ARDRA patterns and sequencing results suggested that in fact we dialed with a single strain instead of two as we assumed at the beginning. Sequencing and phylogenetic analysis of 16S rDNA indicated a 99 % affiliation at the Pseudomonas stutzeri species
