摘要: Lactate production by immobilized Lactobacillus casei has been studied. The cells were in alginate and the effect of variations different parameters on product formation productivity was investigated. performance reaction evaluated stirred batch as well packed-bed conditions. pH control a problem reactor. In experiments, nearly total glucose utilization observed with lactate yield 90–99% 1.6 g·l−1·h−1. Under standard conditions only low percentage (3–4%) formed abetd-isomer. When reused, increased abetd-lactate took place, especially when cell sub-optimal. After revitalization exposure to growth nutrients balance restored.
