Mycelium of Streptomyces cinnamonensis mutant strains cultivated in a synthetic medium with glycine produced protoplasts after lysis of cell walls with lysozyme. The protoplast yield was up to 95%. The protoplasts could revert and mycelial forms were

Using the Koenigs-Knorr method two isomeric monohydroxynaphthoquinones were glucosidized, i.e. 2-hydroxy-1,4-naphthoquinone (lawson, Ia) and 5-hydroxy-1,4-naphthoquinone (juglone, IIa). The structure of the corresponding glucosides Ib and IIb was pro

Streptomyces aureofaciens glucosidizes 1,2,4-trihydroxy-9,10-anthraquinone (purpurin) added to the cultivation medium to yield the corresponding 2-beta-D-glucoside. The identity of the glucoside was demonstrated by comparing its physico-chemical prop

The immunostimulatory and immunoinhibitory effects of 44 hydroxyanthra- and hydroxynaphthoquinone derivatives in tissue culture were investigated. In the test system used, the final effect, i.e. production of antibodies against sheep red blood cells

Both isomeric monohydroxyanthraquinones (1a, b), three dihydroxyanthraquinones (alizarin 1c, chrysazin 1d, and anthraflavin 1e) and corresponding acetylated (2) and free (3) beta-D-glucosides were screened for antitumour and immunosuppressive activit

In addition to lasalocid, an oligoether coccidiostatic compound, other compounds are synthesized by Streptomyces lasaliensis. Mutants producing either of two antibiotics, lasalocid A or quinomycin A (an antibiotic of quinoxaline character), were obta

The GC-MS method was used to analyze fatty acids in a parent strain of Streptomyces lasaliensis and its two mutants producing only lasalocid or quinomycin. The biosynthesis of these substances bears relation to differences in the relative proportion
