Production of industrially important metabolite from raw glycerol

Hiren Patel, Khushbu Patel, Gaurav Shah

Abstract :

Microbial conversion of glycerol into value added products was investigated aiming to facilitate the utilization of waste glycerol. The crude glycerol from biodiesel production represents an abundant and inexpensive source which can be used as raw material for lactic acid production. The first aim of this investigation was to select a suitable strain for producing lactic acid from glycerol with a high concentration and productivity. The second aim was to obtain the optimum fermentation conditions, as a basis for large-scale lactate production in the future. Lactobacillus delueckii strain gave higher production of lactic acid (4.3 gL-1) in batch flask fermentation having raw glycerol as carbon source under agitation at 200 rpm, pH 6.5 and temperature 420C. As compared with pure glycerol, Lactobacillus delueckii gave lower lactic acid production (1.6 gL-1) under same environmental condition. So, raw glycerol containing medium is more favorable for lactic acid production compare to pure glycerol containing medium
