dc.description.abstract Eight bacteria capable of using diesel fuel as the sole carbon source were isolated from both a bunker oil -saturated soil sample and from a gasoline -contaminated water sample . The three isolates from the soil were identified as Pseudomonas vesicularis . And two strains of Pseudomonas aeruginosa . The five water isolates were identified as Achromobacter xvloxidans . Achromobacter sp . , Aeromonas sp . , Pseudomonas sp . , and Pseudomonas vesicularis . The components of diesel fuel degraded by the isolates over a three week period were determined by capillary gas chromatography . The growth curves of the isolates in 1 .5 % yeast extract and in basal salts medium with diesel as carbon source were obtained . The generation times of each isolate in 1 .5 % yeast extract and in basal salts medium with diesel as carbon source were calculated and the significant differences in generations times were determined . Two sets of mixed cultures were used , one consisting of the three soil isolates and the other of the five water isolates , to determine the effect of mixed cultures on diesel over a three week period . The mixed cultures were found to be more efficient than the pure cultures at reducing the total number of fractions of diesel . en_US
