Abstract

The possibility of using starchy tubers (potato, sweet potato and tapioca) as raw materials in glutamic acid production by fermentation by Micrococcus glutamicus was studied. Preliminary work was done on potato which, after enzyme hydrolysis and removal of excess biotin, gave an accumulation of extracellular glutamic acid. A simple technique to remove excess biotin by adsorption on activated charcoal is described, necessitated because of the ineffectiveness of additions of penicillin, isobutyl and isopropyl alcohols and sodium oleate in the system. In a medium containing potato hydrolysate (5% total soluble solids), 0.3% urea, 0.2% peptone, 0.2% meat extract, 0.2% K2HPO4, 0.2% KH2PO4, a yield of 10.75 mg/ml of glutamic acid was obtained after 72 h in agitated culture (vol. 200 ml) at room temp. (28-30 degree C).
