| biosurfactant-producing bacillus are present in produced brines from oklahoma oil reservoirs with a wide range of salinities. | nine wells producing from six different reservoirs with salinities ranging from 2.1% to 15.9% were surveyed for presence of surface-active compounds and biosurfactant-producing microbes. degenerate primers were designed to detect the presence of the surfactin/lichenysin (srfa3/lica3) gene involved in lipopeptide biosurfactant production in members of bacillus subtilis/licheniformis group and the rhlr gene involved in regulation of rhamnolipid production in pseudomonads. polymerase chain reaction ... | 2011 | 21562978 |
