The production of an extracellular endo-(1→3)-β-D‐glucanase by Bacillus sp. no. 215 was induced during growth with (1→3)-β-D-glucan (curdlan) from Cellulomonas flavigena strain KU as carbon and energy source. Maximum levels of activity (0.26 U ml-1 resp. 1.40 U mg-1) were detected in cell-free culture supernatant fluid after 25 h of aerobic growth at 55°C. The cells secreted an endo-(1→3)-β-D-glucanase with low electrophoretic mobility that used curdlan from C. flavigena strain KU and from Agrobacterium sp. (formerly Alcaligenes faecalis var. myxogenes) as substrates. The enzyme activity was highest at pH 7.0 and 55°C. It exhibited a remarkably low thermal stability with a half‐life of 14 min at 55°C in the presence of substrate. Divalent metal cations were required for enzyme activity.
