A thermophilic, N,N'-diacetylchitobiose((GlcNAc)_2)-producing bacterium, strain X-7u, was isolated from hot spring water and identified as Bacillus licheniformis. When X-7u was cultivated in a medium consisting of 2.0% colloidal chitin, 0.05% yeast extract and inorganic salts at 50℃ under shaking, (GlcNAc)_2 was accumulated to a concentration of 9.6 g/l within 5 days. This corresponded to 46% of the stoichiometric yield of (GlcNAc)_2. The strain also produced a small amount of N,N'N"-triacetylchitotriose. However, neither N-acetylglucosamine nor other oligosaccharides were accumulated throughout the culture period.
