A NEW PSYCHOACTIVE BACTERIUM CLOSTRIDIUM-FIMETARIUM, ISOLATED FROM CATTLE MANURE DIGESTED AT LOW-TEMPERATURE

A new psychroactive saccharolytic anaerobic organism was isolated from cattle manure digested at 6 degrees C. The organism is a Gram-positiv e oligosporous motile rod measuring 0.5 - 0.6 by 2.1 - 5.0 mu m. It ut ilizes glucose, fructose, maltose, arabinose, xylose, cellobiose, gala ctose, and mannose. Fermentation products are acetate, ethanol, lactat e, formate, H-2, and CO2. Growth is possible within a temperature rang e of 1 - 30 degrees C, with an optimum at 20 - 25 degrees C, and a pH range of 5.5 - 8.3, with an optimum at 6.8. The DNA GC content is 35.6 mol %. The organism was classified as a new species of the genus Clos tridium, C. fimetarium sp. nov. The type strain is Z-2189.
