Detection and isolation of new glycosides in culture broths of Streptomyces hygroscopicus.

Characterization of new glycosides from the fermentation broths of Streptomyces hygroscopicus.

Studies on a new polyether antibiotic, Ro 21-6150.

A new polyether antibiotic, Ro 21-6150, has been isolated from culture broths of Streptomyces hygroscopicus, strain X-14563. Ro 21-6150 has ionophore properties and is active in vitro against gram-positive bacteria.

جداسازی و تأیید مولکولی سریع استرپتومایسس های تولید کننده آنتی بیوتیک استرپتومایسین

Introduction: Streptomyces species are mycelial, aerobic gram-positive bacteria that are isolated from soil and produce a diverse range of antibiotics. Streptomyces griseus produces the antibiotic, streptomycin and forms spores even in a liquid culture. The gene cluster for the production of Streptomycin antibiotic contains strR gene that encodes StrR, a pathway-specific regulator. Then, this p...

Draft Genome Sequence of Streptomyces hygroscopicus subsp. hygroscopicus NBRC 16556

Here, we report the draft genome sequence of strain NBRC 16556, deposited as Streptomyces hygroscopicus subsp. hygroscopicus into the NBRC culture collection. An average nucleotide identity analysis confirmed that the taxonomic identification is correct. The genome sequence will serve as a valuable reference for genome mining to search new secondary metabolites.

Development of a gene cloning system for Streptomyces hygroscopicus subsp. yingchengensis, a producer of three useful antifungal compounds, by elimination of three barriers to DNA transfer.

Streptomyces hygroscopicus 10-22 could not be transformed with any of the commonly used Streptomyces plasmid vectors and was resistant to plaque formation by the Streptomyces phages phi C31 and R4. Repeated selection resulted in the isolation of derivatives of S. hygroscopicus 10-22 that could be transformed with pIJ101- and pJV1-derived cloning vectors and of restriction-deficient derivatives ...
