Acid production from 13 kinds of carbon sources by Pullularia pullulans, having a high ability to oxidize glucose to gluconic acid, was examined in CaCO_3-contatining media and cultured on a shaher. Lactose and ethanol were not metabolized. Gluconic acid was produced from maltose, sucrose, dextrin and soludle starch, but the yields were much lower than that from glucose. Xylonic and monnonic acids were formed from xylose and mannose, respectively. Malic and fumaric acids were produced along with a small amount of succinic acid from all metabolizable sugar tested. From glucose, however, gluconic acid was formed almost exclusively and extremely poor byproducts. The production of such dicarboxylic acids may be the most remarkable characteristic of oxidative metabolism of sugar by P. pullulans, in comparison with other gluconic acid-producing microorganisms.
