| diversity of biosurfactant producing microorganisms isolated from soils contaminated with diesel oil. | biosurfactant production is a desirable property of hydrocarbon-degrading microorganisms (hdm). we characterized biosurfactant producing microbial populations from a long beach soil, california (usa) and a hong kong soil (china), contaminated with diesel oil. a total of 33 hydrocarbon-utilizing microorganisms were isolated from the soils. twelve isolates and three defined consortia were tested for biosurfactant production and emulsification activity. the highest reduction of surface tension was ... | 2005 | 16035236 |
