The lactic acid production from corn thin stillage using Lactobacillus rhamnosus ATCC 7469 in a batch system was studied. The fermentation temperature was optimized taking into account lactic acid production and glucose consumption as well as other significant process parameters (such as lactic acid yield and volumetric productivity). Also, the effect of pH control on lactic acid production by addition of 1% (w/w) CaCO3 and 10M NaOH was investigated. Based on the obtained results, an optimal fermentation temperature of 41 0C was selected. In this case, lactic acid yield of 0.70 g/g and utilized glucose of 72.55% were achieved. The addition of 10 M NaOH after 72h of fermentation at optimal temperature improved substrate (glucose) utilization for 63.70% compared to the control sample.
