Two thermophilic archaea belonging to the genus Sulfolobus , grown on glucose, produced an extracellular polysaccharide (EPS). The production of EPS conducted both in 90 1 fermentor and in batch culture reached the maximum during the stationary phase of growth. The chemical analysis (FT‐IR, HPAE‐PAD, UV, Optical Rotation) of the biopolymer and of its acid hydrolizate suggested glucose, mannose, glucosamine and galactose as major components of the sulfated heteropolysaccharide.
