| characterization and properties of biosurfactants produced by a newly isolated strain bacillus methylotrophicus dcs1 and their applications in enhancing solubility of hydrocarbon. | six biosurfactant-producing bacteria were isolated from hydrocarbon contaminated soils in sfax, tunisia. isolates were screened for biosurfactant production by different conventional methods including hemolytic activity, surface tension reduction, drop-collapsing and oil displacement tests. all these screening tests show that all the isolates behave differently. among the isolated bacteria, dcs1 strain was selected for further studies based on its highest activities and it was identified as baci ... | 2016 | 27628335 |
