Abstract

The production of Lactic acid from Brewery Spent Grain using Lactobacillus plantarum ATCC 8014. was carried out in this study. Box Behnken Design (BBD) (Design expert® 7 software) was used to investigate the effect of temperature, reaction time and acid concentration during the hydrolysis. Fermentation of the hydrolyzate was performed at 35 °C, pH 5.0-5.5 and 200 rpm for 72 h.
