| Research Abstract |
1.The bioaugmentation method (BA) is a useful technology for decontamination of petroleum-contaminated soils. For this purpose it is necessary to isolate petroleum-degrading bacteria with high activity and to apply such bacteria to soils. To promptly respond to oil spills from oil tankers and tanks isolation and characterization of oil-degrading bacteria should be also prompt. In this study I aimed to develop prompt isolation procedures of petroleum-degrading bacteria.
2.Isolation of petroleum-degrading bacteria from soils (petroleum-contaminated and petroleum-non-contaminated soils) was achieved by cultivating them with soil extracts.
3.Petroleum-degrading isolates from soils are generally able to efficiently degrade petroleum under liquid cultivation conditions. However, most of them did not exhibit significant degrading activity of petroleum in soils.
4.One strain from petroleum-non-contaminated paddy soils was isolated.
