Iran Journal Article 2012 07 07 Production of lysine by <em>Corynebacterium glutamicum </em>(PTCC 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. For this purpose, ammonium sulphate was selected as a constant nitrogen source. The effect of different nitrogen sources was also investigated with glucose as a constant carbon source. The production of L-lysine was examined qualitatively and quantitatively using thin layer chromatography (TLC). Results of fermentation experiments showed that the maximum yield corresponded to molasses (48 g L^-1) for the fermentation period of 96 hours. For other substrates the yield was lower and the period of fermentation exceeded that for molasses. https://iar.shirazu.ac.ir/article_189_7ff44c2e748bf4f05aa2e3a88188046e.pdf
