| Abstract: | The effect of pH value, temperature and soluble oxygen on the deep liquid fermentation of cellulose-enzyme with a trichoderma green were studied. In a 10-litre aerate fermentation jar with machine mix round,the dosage of inoculation was 10%.The pH value,temperature and soluble oxygen were controlled step by step. The enzyme reached peak activity when ferment for about 72 h. FPA enzyme and CMC enzyme reached to 67 U/mL and 375 U/mL. |
