| 英文摘要 | A biosurfactant-producing strain z25 was isolated from the oil production water in daqing oilfield, china. the strain was identified as rhodococcus ruber by 16s rdna sequencing. rhodococcus ruber z25 showed a preference of alkanes as carbon sources for biosurfactant synthesis. the optimal biosurfactant production was achieved at the nacl concentration of 2.5% at 34 degrees c. in batch cultivation, r. ruber z25 exhibited a cell-growth associated biosurfactant-producing process on n-hexadecane and the maximum yield of biosurfactant production was 13.34 g/l at 44 h. the rate of biosurfactant production per unit biomass (r-(biosurf/biomass)) was used to characterize the biosurfactant-producing profile. a two-stage biosurfactant-producing profile of r. ruber z25 was established by the r-(biosurf/biomass) curve, exhibiting the biosurfactant production in correlation with cellular hydrophobicity and biomass accumulation. the crude biosurfactant was extracted by methyl tert-butyl ether (mtbe) method and only one glycolipid fraction at rf value of 0.64 was detected by thin layer chromatography (tlc) analysis. |
