摘要
采用一种植物纤维木糖渣为原料，对纤维酶水解及同时糖化和发酵（ Ｓ Ｓ Ｆ） 过程进行了研究。研究结果表明，在纤维素含量为４２ｇ· Ｌ１ 、纤维素酶的加入量为２８０ Ｆ Ｐ Ｉ Ｕ· Ｌ１ 、乳酸菌用量为０ ．５ｇ· Ｌ１ 时，乳酸对纤维素的转化率可达８０ ％ ，并从反应机理及动力学角度出发，建立了纤维素酶水解与 Ｓ Ｓ Ｆ 过程的数学模型。
The process of the plant cellulose enzymatic hydrolysis and simultaneous saccharification and fermentation (SSF) was studied by using a plant cellulose—spent residue of xylose production as raw material.The results showed that the percent conversion of lactic acid to cellulose reached 80% when the content of cellulose was 42g·L 1 ,the concentrations of celluose enzyme and lactobacillus delbrium were 280 FPIU·L 1 and 0.5g·L 1 respectively.Based on the reaction mechanism and kinetics,a mathematic model was suggested.
