Abstract
A strain of A. acetigenum, isolated from E. African vinegar, formed cellulose from all of 18 carbohydrates, or alcohols related to carbohydrates, which were submitted to its action. By its ability to convert to cellulose the alpha- and beta-methyl-D-glycosides, 3 pentoses, erythritol and ethylene glycol, respectively, the new organism showed itself to be enzymically more active than A. xylinum which, in previous studies of cellulose formation (Tarr and Hibbert, 1931), proved unable to utilize these substances for this purpose. During the formation of cellulose from ethylene glycol and from glycerol there were formed glycolaldehyde and glyceraldehyde, respectively, and these were characterized as their osazones. A. acetigenum, A. pasteurianum (an atypical strain) and A. kutzingianum can each synthesize cellulose when grown on suitable media.
