| Abstract: | A bacterium strain named 10# was isolated and screened from oil-contaminated samples,which was identified as Bacillus sp. Strain 10# exhibited a high degree of demulsification activity against the oil-in-water(o/w)emulsion of petroleum industry. The optimum growth conditions of the strain 10# were temperature 30 ~35℃ ,pH 7.0 ~7.5,time 48 ~72h,with atoleine as carbon source. Strain 10# had powerful and stable demulsification activity after growing for 48h. Only thalli had demulsification activity. |
