The distribution of β-lactamase activities in a collection of actinomycete strains was surveyed. Six of 127 strains were found to produce β-lactamase. This low frequency was in contrast to the case wi
An alkaliphilic actinomycete, Nocardiopsis prasina OPC-131, secretes chitinases, ChiA, ChiB, and ChiBΔ, in the presence of chitin. The genes encoding ChiA and ChiB were cloned and sequenced. The open
Cellulose is a carbon source widespread in nature. However, it is a difficult task for any organism to get carbon atoms from the cellulose as it has a highly complex structure. Only a few taxonomic gr
