Abstract
A thermophilic obligate methane-oxidizing bacterium, H-2, produced two kinds of extracellular acidic polysaccharides (Polymer I and Polymer II) from methane as a single carbon and energy source. The maximum total polysaccharide production was 1.8g, together with 3.6g of dry cells, per liter of the culture medium. Polymer I and Polymer II contained 37% and 56% of sugars, respectively, consisting of glucose, mannose, galactosamine and glucuronic acid. In addition, these polysaccharides contained about 38% and 30% of amino acids, respectively.Keywords
