Biosynthesis of butyric acid from cabbage stem and molasses by the strain Clostridium butyricum VKPM B-9619

The acidogenesis of the strain Clostridium butyricum VKPM B-9619 on synthetic medium SOL, a fermentative hydrolyzate of cabbage stem, and molasses as cheap sources of carbohydrate nutrition of micro-organisms, has been studied. The yield of butyric acid was no less than 43%. It was found that, in addition to hexoses, the strain ferments pentoses (xylose and arabinose), which enables the processing of wastes of pentosan- and cellulose-containing plant raw materials with the addition of molasses. The fermentation liquid of the strain can be used for the isolation of butyric acid by the ion exchange method.
