In an extensive numerical phenetic survey, a numberof blue, red and gray spored streptomycete strainswere grouped together as Streptomyces cyaneusspecies-group, a taxon which encompasses strainsknown to produce antitumor antibiotics, notably anthracyclines.In the present investigation these and relatedstreptomycetes were the subject of morphological and...

Streptomyces azureus ATCC 14921 belongs to the Streptomyces cyaneus cluster and is known to be a thiostrepton producer. Here, we report a draft genome sequence for this strain, consisting of 350 contigs containing a total of 8,790,525 bp, 8,164 predicted coding sequences, and a G+C content of 70.9%.

Lettuce drop, caused by the soil borne pathogen Sclerotinia sclerotiorum, is one of the most common and serious diseases of lettuce worldwide. Increased concerns about the side effects of chemical pesticides have resulted in greater interest in developing biocontrol strategies against S. sclerotiorum. However, relatively little is known about the mechanisms of Streptomyces spp. as biological co...

Chitinase A of Streptomyces cyaneus SP-27 or chitinase I of Bacillus circulans KA-304 showed the protoplast-forming activity when combined with alpha-1,3-glucanase of B. circulans KA-304. The gene of chitinase A was cloned. It consisted of 903 nucleotides encoding 301 amino acid residues, including a putative signal peptide (35 amino acid residues). The deduced N-terminal moiety of chitinase A ...

The enzymes from the microbial sources are more stable and can be obtained cheap sources. Amylase is most important industrial enzyme which widely used in food biofuel industries. Streptomyces a group of bacteria belongs to largest genus Actinobacteria commonly isolated soil. species have been as cell industries for production antibiotics. For antibiotics, frequently cells. This study reported ...

Trejo, W. H. (Squibb Institute for Medical Research, New Brunswick, N.J.) and R. E. Bennett. Streptomyces species comprising the blue-spore series. J. Bacteriol. 85:676-690. 1963.-The objective of this study was to define and delimit the streptomycetes of the blue-spored (Viridochromogenes) series. The series, as defined in this study, includes 11 blue and blue-green species. The green-spored s...

A culture filtrate of Bacillus circulans KA-304 grown on a cell-wall preparation of Schizophyllum commune has an activity to form protoplasts from S. commune mycelia. alpha-1,3-Glucanase and chitinase I, which were isolated from the filtrate, did not form the protoplast by itself while a mixture of them showed protoplast-forming activity. Streptomyces cyaneus SP-27 was isolated based on the pro...

As a result of screening for inhibitors of glycerol-3-phosphate dehydrogenase, which may be effective to prevent corpulence, we isolated two inhibitors named adipostatin A and adipostatin B from the culture broth of Streptomyces cyaneus 2299-SV1. Their structures have been established to be 5-n-pentadecylresorcinol and 5-isopentadecylresorcinol, respectively. Adipostatin A and adipostatin B inh...
