Abstract
Ethanol production from 200 g lactose/l by Kluyveromyces fragilis immobilized in calcium alginate was 63 g/l whereas with co-immobilized K. fragilis and Zymomonas mobilis 72 g ethanol/l was attained. With free cells of K. fragilis, only 52 g ethanol/l was obtained. The beads were relatively stable without significant reduction in activity for about six batches of fermentation.
摘要
弗氏丙酸杆菌固定化于海藻酸钙后用于 200 g/L 乳糖生产乙醇，产量为 63 g/L；而当共固定化弗氏丙酸杆菌和运动发酵单胞菌时，乙醇产量可达 72 g/L。游离弗氏丙酸杆菌细胞的乙醇产量仅为 52 g/L。这些微球相对稳定，在大约六批发酵过程中没有明显的活性降低。
