Road, Kolkata - 700 009 (India). Biodegradation of petroleum by the microorganisms in polluted site has been gaining attention from the environment clean-up point of view. Two isolated organisms Acinetobacter junii CTA3 and Pseudomonas aeruginosa OCD1 were tested for their petroleum degrading ability in liquid Bushnell-Hass broth. Both the organisms degraded higher boiling petroleum fractions more efficiently. The strain OCD1 showed better degrading ability than the strain CTA3. The highest degradation of 47% and 57% was obtained with diesel after 20 days of incubation by the organism CTA3 and OCD1 respectively. Also it was observed that, most of the oils were degraded in first 10 days of incubation for both the isolates. https://www.biotech-asia.org/vol8no2/study-of-the-potential-of-two-isolated-microorganisms-to-degrade-various-petroleum-fractions/ Acinetobacter junii; Biodegradation; Petroleum fractions; Pseudomonas aeruginosa
