摘要
本文报道加入甾醇、不饱和脂肪酸和改变氯化钙浓度对固定化凝胶粒子机械强度及发酵的影响。
Both unsaturated fatty acid and sterol that were added into the mixture of alginate and Saccharomyces cerevisiae cells during properation of immobilized growing cells were able to enhance the mechanical strength, elastieit and stability of immobilized cells. The yield of ethanol produced by immobilized growing cells containing both unsaturated fatty acid and sterol was about 6.84% more than that produced by immobilized growing cells without both unsaturated fatty acid and sterol.The mechanical strength, elasticity and amount of cells of immobilized gelled in 2% solutiort of calcium chloride were higher than that of immobilized growing cells gelled in 1%, 4% and 8% solution of calcium chloride.
