[2H26]-1-epi-Cubenol, a completely deuterated natural product from Streptomyces griseus

Five new cadinane-type sesquiterpenes from the heartwood of Chamaecyparis obtusa var. formosana.

Muurola-4,10(14)-dien-3-one (1), 10-O-acetyl-15-oxo-alpha-cadinol (2), 15-hydroxy-alpha-cadinol (3), 4alpha-hydroxy-5beta-ethoxy-epi-cubenol (4), and 4alpha-hydroxy-5beta-acetoxy-epi-cubenol (5), five new bicyclic sesquiterpenes, have been isolated from the heartwood of Chamaecyparis obtusa var. formosana along with the known compounds epi-cubenol, T-cadinol, T-muurolol, delta-cadinol, and alph...

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...

Streptomyces griseus 45H, a producer of the extracellular autoregulator protein factor C, is a member of the species Streptomyces albidoflavus.

Streptomyces griseus strain 45H, isolated in 1960 during a mutagenesis programme on the industrial streptomycin producer S. griseus 52-1, encodes an extracellular, pleiotropic autoregulatory signalling protein, factor C, which stimulates sporulation of S. griseus 52-1 in submerged culture. The facC gene, which codes for factor C, is present in very few streptomycetes and is not present in S. gr...

Genome sequence of Streptomyces griseus strain XylebKG-1, an ambrosia beetle-associated actinomycete.

Streptomyces griseus strain XylebKG-1 is an insect-associated strain of the well-studied actinobacterial species S. griseus. Here, we present the genome of XylebKG-1 and discuss its similarity to the genome of S. griseus subsp. griseus NBRC13350. XylebKG-1 was isolated from the fungus-cultivating Xyleborinus saxesenii system. Given its similarity to free-living S. griseus subsp. griseus NBRC133...
