Dual Mode Fermentation For Production Of Lactic Acid
Abstract: The invention provides an efficient dual mode fermentation process comprising of employing free cell population as well as cells immobilized on an immobilizing means for fermenting the suitable carbohydrate source to produce various metabolites particularly lactic acid with improved efficiency of conversion rate of sugar to lactic acid to more than about 50% and better productivity in terms of yield more than about 50%. For producing lactic acid, the present invention process uses a cheap source of carbon like molasses. The present invention also employs a means for immobilizing cells like polyurethane foam to carry out fermentation continuously without any compromise on the yield or productivity of the metabolite. Also provided in accordance with the present invention is an integrated dual fermention system essentially comprising of a fermentor tank, coupled with a packed bed biofilm column which serves as a continuous source of inoculum thereby removing the need of repeated inoculations for sustaining the cell population density.
