Abstract
Growth and acid formation of lactic acid bacteria were examined under batch operating conditions for various micro-organism strains in order to find the most efficient strain for lactic acid production. In addi tion, production of lactic acid from deproteinized whey using the effi cient strain immobilized in an agar gel and fermented in a continuous fixed bed reactor was investigated. The optimal processing temperature and dilution rate were found to be 40 degrees C and 0.33 h(-1), Maxim um volumetric productivities of lactic acid from whey were 7.28 and 9. 36 gl(-1) h(-1) without and with recycle, respectively.
