Lactic acid is a very important chemical having various applications in the field of pharmaceutical, cosmetics, textile, leather and food industries. 85% of lactic acid is used in the food related applications but recently it has drawn much attention to many other industrial
applications like biodegradable plastic production. Lactic acid is able to be produced by chemical synthesis or bacterial fermentation, but none of chemical production routes shows technical and economical viability. Significant advantage of biotechnological production of
lactic acid by fermentation over chemical synthesis is that can use cheap raw materials The raw material cost for the fermentative production of lactic acid usually accounts for 68% of total manufacturing cost. Among the nutrient sources available, cellulosic and hemicellulosic
materials are renewable and most abundant. Enzymatic hydrolysate of wood has been regarded as one of the most inexpensive carbon source for the fermentative production of biochemicals. Even though wood hydrolysate is a good source for fermentable glucose and xylose, it
contains some unknown toxic or inhibitory compounds for cells.In this presentation, we will show the production of lactic acid using several lactic acid bacteria utilizing lignocellulosic hydrolysate. Detailed results will be presented.
