- A psychrotrophic bacterium was isolated from oil-contaminated groundwater and identified as Rhodococcus sp. YHLT-2. Growth was observed at the temperature of 4 to 30 degrees C. This strain degraded various petroleum hydrocarbons such as crude oil, diesel oil, and gasoline over the whole range of temperatures tested. The Rhodococcus sp. YHLT-2 was capable of growing even at 4 degrees C, exhibiting 90% of oil biodegradation after 20 days. Degradation of crude oil Occurred at low temperature in nature. This strain was also able to grow at 7% NaCl, and utilized not only short chain alkenes (C-9 to C-12), but also a broad range of long chain alkenes (C, to C, C-32) present in Crude oil at 4 degrees C. The Rhodococcus sp. YHLT-2 is expected to be of potential use in the in situ bioremediation of hazardous hydrocarbons under low-temperature and high-salt conditions.
