Abstract

3-monomethyl glucose (I), 1, 2, 3, 5-tetramethyl glucose (II), and 1, 2, 3, 5, 6-pentamethyl glucose (III) were prepared, and, together with pectin, tried out on 185 cultures including organisms isolated from the activated sludge of creamery wastes and members of the colon-typhoid group. A peptone medium was used and a synthetic medium containing no peptone and hence no carbon other than the carbon of the pectin or carbohydrates. The organisms digesting pectin and (I) with the production of acid and gas were those commonly associated with the soil. (II) and (III) were not digested by any of the organisms tried. Conclusions based upon these results were discussed.
