摘要
对采用基础培养基分批培养过程中羧甲基纤维素钠(Carboxymethyl cellulose sodium,CMC)固定化烟曲霉(Aspergillus fumigatus)活菌体小球中菌体的生长动力学和基质消耗动力学进行了考察,结果表明,Logistic方程能很好地反映CMC固定化烟曲霉活菌体小球中的菌体生长动力学,CMC固定化烟曲霉活菌体小球中的菌体生长未受到明显抑制;基质消耗动力学方程可以根据产物合成模型Luedeking-Piret方程得到。
The multiplication and substance consuming kinetics of biomass entrapped in Carboxymethyl Cellulose Sodium （CMC） immobilized live Aspergillus fumigatus beads was investigated through batch cultivation in the basic culture media. The results showed that the growth kinetics of biomass entrapped in CMC immobilized live A. fumigatus beads fitted well to Logistic model. The growth of biomass was not inhibited obviously. The substance consuming kinetics equation could be obtained by products synthetical model viz. Luedeking-Piret equation.
