Constitutive and Inducible Expression of the rRNA Methylase Gene erm(B) in Campylobacter.

abstract：:The gram-positive bacterium Streptomyces noursei ATCC 11455 produces a complex mixture of polyene macrolides generally termed nystatins. Although the structures for nystatins A(1) and A(3) have been reported, the identities of other components of the nystatin complex remain obscure. Analyses of the culture extract fro...
