Abstract:
This disclosure describes a new antibacterial and anti-tumor agent designated LL-D05139 .beta., produced in a microbiological fermentation under controlled conditions using a new genus Glycomyces harbinensis gen. nov., sp. nov., and mutants thereof.
Abstract:
This invention relates, in part, to macrolide compounds, actinomycete strains for producing them, and pharmaceutical compositions containing them.
Abstract:
Antibacterial and antitumor agents designated LL-E33288 complex and their production by new strains of Micromonospora echinospora ssp. calichensis NNRL-15839, NRRL-15975 and NRRL-18149, are disclosed.
Abstract:
The invention is a process for the production by fermentation of the antibacterial and antiparasitic agents designated LL-D42067.alpha., to methods for its recovery and concentration from crude solutions and to processes for its purification. The invention includes within its scope the biologically pure culture of the antibiotic.
Abstract:
