摘要
Abstract
Thermophile strain ZY-3 for enhancing oil recovery was cultivated at 60℃for 7 d in the media with xylose,starch, glucose, paraffin and the mixture of paraffin and saccarides as carbon sources. The growth and metabolism related with surface activity of the strain was evaluated by measuring the bacteria growth, surface tension, emulsifying activity and the residues of carbon sources.The results showed that the strain ZY-3 could utilize the tested carbon sources for the growth of cells and the production of biosurfactants.The mixed carbon source of paraffin with glucose or starch could not obviously promote cell growth, but significantly reduce surface tension of fermented broth, the emulsification activity of the broth fermented for long time could also increased significantly.Starch could significantly reduce the consumption of paraffin.The mixed carbon source of paraffin and xylose could improve the growth of cells,but had no obvious effect on the reduction of paraffin consumption and the enhancement of surface activity of fermented broth.关键词
