Abstract:
      Seven thermophilic strains G1-G7 were obtained according to the high temperature domestication and plate screening of T. cutaneum CX1. At 42℃, the dry weight of strain, oil accumulation and oil content of the thermophilic strain G3 were 11.13,1.33 g/L and 11.95% respectively, increasing by 32.8%,46.2% and 10.0% respectively comparing with original strain, so the advantage of fermentation was obvious. The analysis results of fatty acid composition of cytomembrane showed that the thermophilic strain G3 had higher content of saturated fatty acids in cytomembrane than original strain, meanwhile, the content of saturated fatty acids in cytomembrane of the thermophilic strain G3 increased further with the cultural temperature rising.
