β-Amylase Production by a Rifampin-resistant, Asporogenous Mutant fromBacillus cereusBQ10-Sl

Microbial Enzymes and Biotechnology

“…It was inhibited by Schardinger cyclodextrins, p-chloromercuribenzoate (p-CMB) and N-bromosuccinimide. An asporogenous mutant, strain BOlO-SI Spo II, that was rifampin-resistant was selected from BOlO-SI and gave a four-fold increase in fJ-amylase production (Nanmori et al, 1983). The suggestion that this is not a thiol enzyme (Marshall, 1974) is not compatible with these observations.…”
