title: Carbon and nitrogen nutrition of Aerobacter aerogenes for valine production.
abstract: A number of carbon and nitrogen compounds were tested for their effect on growth of Aerobacter aerogenes and valine production. Sucrose was found to be the superior carbon source for valine production, while mannose supported maximum cellular growth with very poor yield of valine. Urea was found to be the adequate nitrogen source for valine production. Supplementation of the synthetic medium with complex nutrients lowered the yield of valine. No direct relationship between the growth of the organism and the formation of the amino acid was noticed. On the basis of this study, a suitable synthetic medium for valine production has been developed.
