Enhanced Production of Poly (γ-glutamic acid) from Bacillus licheniformis NCIM 2324 by Using Metabolic Precursors
2009
Bajaj, Ishwar B. | Singhal, Rekha S.
The aim of the present work was to study the effect of addition of different amino acids and tricarboxylic acid cycle intermediates as metabolic precursors on the production of poly (γ-glutamic acid) (PGA) by Bacillus licheniformis NCIM 2324. A maximum yield of 35.75 g/l was obtained with the medium supplemented with 0.5 mM l-glutamine and 10 mM α-ketoglutaric acid as compared to 26.12 g/l PGA achieved with the control in the absence of metabolic precursors. Addition of precursors also enhanced the utilization of l-glutamic acid during fermentation.
