Abstract:
Fermentation condition optimization of P. decumbens Ju-A10 for production of CMCase using three kinds of plant cellulosic wastes as carbon sources was made using RSA method. The result was that CMCase was the highest when the level of carbon source was 9. 77 % , 8. 69 % and 9. 97% , and liquid volume was 64. 7 mL, 54. 2 mL, 40. 8 mL for carbon sources of millet straw, wheat straw and paper sludge, respectively. The value of CMCase was 29. 26IU/mL, 29. 14 IU/mL, 29. 81 IU/mL, respectively, in the above cases. The value of R2 is 0. 9117 , 0. 9246, 0. 8655 , respectively. It could be concluded that the fermentation models were quite reliable. The method can be applied in optimization of fungi fermentation medium.
