AbstractThe results of morphological, base ratio, nutritional, temperature, and pH studies on a strain of Methanospirillum hungatii, isolated from an anaerobic pear waste digester, are described. The isolate, designated as strain GP 1, was compared with some of the characteristics of type-strain M. hungatii JF 1. Strain GP 1 is Gram-negative, weakly motile, and a strict anaerobe with a guanine plus cytosine (G + C) content of 46.5 mol%. The preferred substrates for methane production are hydrogen, carbon dioxide, and formate. Acetate is used under certain conditions but its specific contribution to cell carbon and (or) methane formation was not established. The optimum temperature for both growth and methane production is 35 °C, but growth and methane production occur over the range 25–45 °C. Methane production is optimal at pH 7.0.
