Abstract

The role of carbon and nitrogen sources on the production of acetone and butanol by alocal strain of C.acetobutylcium was
investigated. Molasses was found to be superior as compared with the othertested mono di and polysaccharides. The highest
solvent yield (17.37 g 1.1) was obtained with a culture medium containing 140 g I-I molasses. (NH4)2S0 4proved to be the
best inorganic nitrogen source whereby a total yield of 17.7 g I-I solvents were obtained at 2 g I-I salt level. Among the
different organic nitrogen soures tested, rice bran and corn bran mixture (5 g I-I each) proved to be the best, where by
18.56 g I-I of total solvents were obtained.
