Abstract

WHEY with a large amount of BOD (50000 PPM) is a dangerous environmental pollutant. This important source of lactose (4-5%) is a usefull substrate for a range of fermentation processes. Lacitic acid with several applications in industries is one of these products. Specially L (+) isomer of this acid worthing 10 times as much as the mixture of L & D, is used in medical purposes such as absorbable surgical filaments and controlled release drugs. Several strains of Lactobacillus produce a mixture of L & D isomers but the strain employed in this research (Lactobacillus casei) produces only L (+) form. The produced lactic acid prevents acid production in fermentation, so that almost half of lactose (about 22g/L lactic acid) is converted to Lactic acid. Therefore in order to increase the output the produced acid should be separated. In this research Lactobacillus Casei was used to produce L (+) Lactic acid and due to strile conditions requirement in situe separation of acid using Ion-exchange resins at control automatic of pH were employed. At the end, Lactic acid yield in non extractive fermentation compared with extractive process showed an increase from 22g/L to 43.7 g/L. The polarimetric analysis showed pure L (+) product.
