- Abstract
Using Issatchenkia orientalis as the research object, the growth situation and ethanol production of I. orientalis FJ-J-3 under different p H and Na2SO4 content stresses were determined by spectrophotometry and GC. The results showed that the OD600 nmvalue(4.8) and ethanol production(1.3%vol) were the highest when the pH was 2.0 and without Na2SO4, the OD600nmvalue(26.5) and ethanol production(3.0%vol) were the highest when the pH was 4.0 and Na2SO4 content was 2%, the OD600nmvalue(27.5) and ethanol production(2.9%vol) were the highest when the pH was 6.0 and Na2SO4 content was 6%, and the OD600nmvalue(20.9) and ethanol production(2.3%vol) were the highest when the pH was 8.0 and Na2SO4 content was 2%. The strain FJ-J-3 had good salt tolerance under the culture conditions of pH=4.0 and pH=6.0, while the salt tolerance of strain FJ-J-3 weakened under the culture conditions of pH=2.0 and pH=8.0.
