摘要：

A halophilic, thermotolerant Bacillus strain (B3-15), isolated from water of a shallow, marine hot spring at Vulcano Island (Eolian Islands, Italy), produced an exocellular polysaccharide at 165 mg l(-1). It grew on kerosene as sole carbon source and was resistant to Cd2+, Zn2+, As2+ and Hg2+. From 16S rDNA analysis, strain B3-15 was related to B. licheniformis. The exopolysaccharide was a tetrasaccharide repeating unit essentially constituted by sugars having a manno-pyranosidic configuration.
