Cloning of the beta-amylase gene from Bacillus cereus and characteristics of the primary structure of the enzyme.

abstract：:Fluorescent antibodies (FAs) prepared against 16 ammonia-oxidizing nitrifying bacteria were examined as to cross-reactivity in heterologous FA staining tests. Virtually all cross-reactions to the seven Nitrosomonas FAs were confined to the Nitrosomonas isolates. The five Nitrosospira, three Nitrosolobus, and one Nitro...
