Inducing yeast cells to self-flocculate could be considered a cell immobilization method. The growth kinetics of the flocs from Schizosaccharomyces pombe was studied in an experimental suspended-bed bioreactor with starch hydrolysate obtained by two-stage enzymatic hydrolysis. It was discovered that a limited oxygen supply was necessary during continuous ethanol fermentation with yeast flocs. The oxygen supplied was a kind of limited substrate effecting on the floc growth. Further, a kinetic model describing this floc growth was proposed.
诱导酵母细胞进行自絮凝可被视为一种细胞固定化方法。在一个实验性悬浮床生物反应器中，研究了来自粟酒裂殖酵母的絮凝物在通过两步酶水解获得的淀粉水解产物中的生长动力学。结果发现，在酵母絮凝物连续乙醇发酵过程中，需要有限的氧气供应。所供应的氧气是一种影响絮凝物生长的有限底物。此外，还提出了一个描述这种絮凝物生长的动力学模型。
