Growth kinetics study and process optimization of lactic acid fermentation in laboratory scale fermenter

The purpose of this research was to study the growth kinetics of Lactobacillus rhamnosus in laboratory scale fermenter and to optimize the production of lactic acid with varying certain operating conditions of fermenter. The experiment was designed by Taguchi Method using STATISTICA software to...
