SCREENING,IDENTIFICATION AND CHARACTERISTIC OF A STRAIN OF FACULTATIVE ANAEROBE METABOLIZING DIESEL / 微生物学通报

The strain of DG7 isolated from the oilwater sample in DAGANG oilfield could produce surfactant ?acids and gas in the culture medium in which the diesel was sole carbon source .The strain was Gram-negative, motive, rod and growed facultatively in the 0 to 18.5% NaCl. Based on its characters, the strain was identified as a member of the genus Aeromonas, but there were some differences between this strain and the described species of this genus in some biochemical features, suggesting that it could be a new species of the genus.
