NEW SPECIES OF PSYCHROPHILIC ACETOGENS - ACETOBACTERIUM BAKII SP NOV, A-PALUDOSUM SP NOV, A-FIMETARIUM SP NOV

摘要

Three strains of new acetogenic bacteria were isolated from several low temperature environments. Cells were gram-positive, oval-shaped flagellated rods. The organisms fermented H-2/CO2, CO, formate, lactate, and several sugars to acetate. Strains Z-4391 and Z-4092 grew in the temperature range from 1 to 30 degrees C with an optimum at 20 degrees C; strain Z-4290 grew in the range from 1 to 35 degrees C with an optimum at 30 degrees C. The DNA G+C content of strains Z-4391, Z-4092, and Z-4290 was 42.1, 41.7, and 45.8 mol%, respectively. [References: 28]
