METHOD OF PRODUCING LACTIC ACID BY CONTINUOUS FERMENTATION |
摘要 |
By a method for producing lactic acid wherein culture of polyploid yeast having a capacity to produce lactic acid is filtered through a porous membrane having an average pore size of not less than 0.01 µm and less than 1 µm and the product is recovered from the filtrate, while the unfiltered liquid is retained in or returned to the culture and a fermentation feedstock is added to the culture, it is possible to remarkably and stably enhance the efficiency of production of lactic acid by fermentation for a long time at a low cost. |
