摘　　要：研究了米根霉的固定化方法，研制了用吸附法固定米根霉的生物转盘反应器，考察了在该反应器中培养基组成及其它操作条件对Ｌ－乳酸发酵的影响。实验结果表明，应用吸附法固定化的米根霉及生物转盘反应器进行Ｌ－乳酸发酵具有发酵速率快。The immobilization method of Rhizopus Oryzae(RO) was studied.The rotating biological contactors for immobilizing RO by adsorption method was developed. The effects of composition of media and other operation conditions on L-lactic acid fermentation were evaluated.The expermental results indicated that.to immobilize RO by adsorption method with the rotating biological contactors the L-lactic acid fermentation is fast in fermentation rate and high in L-lactic acid yield.The bioreactor can be used either in continuous or in repeated batch operation mode.
