Solvent production by Clostridium beijerinckii NRRL B592 growing on different potato media.
Very good solvent formation rates were observed when Clostridium beijerinckii NRRL B592 was cultivated on different whole potato media. The increase in whole potato concentration contributed to the increased final solvent concentrations, while the addition of yeast extract or mineral salts gave negative effects. To obtain good solvent productivities and high final solvent concentrations during batch fermentation, no enzymatic hydrolysis of the potato starch was necessary, indicating high activity of the clostridial amylases produced by the strain applied.
