We are attempting to discover materials as new carbon sources for industrial fermentation. Etyleneglycol is quite easily produced from ethylene which is derived from petroleum.A gram-negative, non-spore-forming bacterium was isolated from soil, capable of growing on a medium containing 10% ethyleneglycol as the sole source of carbon and studied for the ability of ethyleneglycol utilization. The strain (10C3) is able to utilize more easily ethyleneglycol and glycerol among a variety of alcohols and also considerably utilize 1,2-, 1,3-propyleneglycol and choline. 730 mg of dried cells were obtained in 100 ml of a synthetic medium containing 2% ethyeleneglycol, 1% (NH_4)_2HPO_4 and inorganic salts.A polysaccharide was produced in a yield of about 20% in a medium composed of 3% ethyleneglycol, 0.5% yeast extract and 1% CaCO_3. The polymer is not colored with iodine-potassium iodide soluotion and is principally composed of glucose.
