Two new antimycin antibiotics; that is antimycins A19 (1) and A20 (2), were isolated from a cultured broth of marine actinomycete Streptomyces antibioticus H74-18 together with antimycins A1a (3a) and A1b (3b), A2a (4), A3a (5a) and A3b (5b). Their structures were determined by spectroscopic methods in combination with X-ray diffraction. Antimycin A19(More)
We report a draft genome sequence of Dickeya zeae strain MS1, which is the causative agent of banana soft rot in China, and we show several of its specific properties compared with those of other D. zeae strains. Genome sequencing provides a tool for understanding the genomic determination of the pathogenicity and phylogeny placement of this pathogen.
An actinomycete strain, H41-59, isolated from sea sediment in a mangrove district, was identified as Streptomyces anandii on the basis of 16S rDNA gene sequence analysis as well as the investigation of its morphological, physiological and biochemical characteristics. Three new ergosterols, ananstreps A-C (1-3), along with ten known ones (4-13), were(More)
An actinomycete strain 200-09, isolated from a soil sample collected from the coast of Hawaii, USA, was identified as Streptomyces antibioticus on the basis of its morphological, physiological and biochemical characteristics as well as 16S rDNA analysis. A new antimycin-type antibiotic, kitamycin C (1), together with kitamycin A (2), kitamycin B (3),(More)
An actinomycete strain (H12-15) isolated from a sea sediment in a mangrove district was identified as Streptomycesantibioticus on the basis of 16S rDNA gene sequence analysis as well as the investigation of its morphological, physiological, and biochemical characteristics. Two novel benzamido nonacyclic dilactones, namely neoantimycins A (1) and B (2),(More)
OBJECTIVE To isolate and purify a new polysaccharid Streptomyces polysaccharid polysaccharide (SMP ), from cultured broth of a Streptomyces sp.strain and perform its structural analysis. METHODS Ethanol was used to precipitate the polysaccharides and macromolecules from the broth. The proteins in the precipitate were removed by Sevage method and(More)
Anandins A (1) and B (2), two rare steroidal alkaloids, were isolated from the fermentative broth of a marine actinobacteria Streptomyces anandii H41-59. The gross structures of the two alkaloids were elucidated by spectroscopic methods including HR-ESI-MS, and NMR. Their absolute configurations were confirmed by single-crystal X-ray diffraction analysis(More)
An actinomycete strain, H41-55 from sea sediment was identified as Streptomyces antibiotic on the basis of its morphological, physiological and biochemical characteristics as well as 16S rDNA data. A new secondary metabolite, (2S,3R)-N-[3-(formylamino)-2-hydroxybenzoyl]-l-threonine propyl ester (1), together with five known compounds was isolated from(More)
