摘要：

A new halophilic cellulolytic bacterium isolated from hypersaline lagoons of Lake Sivash (Crimea) is described. The organism is an obligate anaerobe. Concentrations of between 5% and 20% NaCl are required for growth; optimum growth occurs at a concentration of 15% NaCl. The cells are Gramnegative, motile rods, 0.4-0.6 x 3.8-12.0 mu m in size. Cellulose, starch and a wide variety of carbohydrates are utilized. The products of cellulose fermentation are acetate, ethanol, lactate, hydrogen and carbon dioxide. The temperature range for growth is 20-50 degrees C (opt. 39 degrees C). The pH range is 5.5-8.5 (opt. 7.0). The G+C content of the DNA is 29 mol.%. The bacterium differs from other anaerobes and halophiles described in the literature. The name Halocella cellulolytica gen. nov., sp. nov. is proposed. The type strain is z-10151.
