and lessening workloads. In order to decrease inaccuracy, subculture and resting
cells were inoculated into mineral salt medium with 200 μl oil in well plates for the cultivation at 37 °C for 5
and 7 days, and the biodegradation potential was characterized by the changes of oil film and cell density.
With appropriate evaluation by shaking flask tests, 5 isolates were retained for their potentials with the maxi-
mum biodegradation from 1500 to 2200 mg · L−1 and identified as
