dc.description.abstractA strain similar to Dictyoglomus thermophilum, isolated from a New Zealand hot spring, is described. This strictly anaerobic, Gram-negative, non-motile and nonsporulating bacterium usually exists as long thin filaments of 5 to 25 µm by 0.35 to 0.45 µm. Rotund bodies are commonly observed. Thin sections of the cells revealed a two-layered cell wall. The optimum temperature and pH for growth was 70°C and 7.0 and 7.5 respectively. No growth was observed at 40°C and 85°C or at pH 4.5 to pH 9.0. The organism fermented glucose, maltose, mannose, xylose, lactose, cellobiose, galactose and sucrose and produced acetate as the major end-product with significant amounts of lactate, H2 and CO2 and only traces of ethanol. The doubling time on glucose was 10 h. The DNA base composition was 29.5% guanine plus cytosine as determined by the thermal denaturation method. Growth was inhibited by penicillin, tetracycline and chloramphenicol indicating that the organism was a eubacterium. These features are in common with the newly described species Dictyoglomus thermophilum to which the New Zealand isolate belongs.en_NZ
