Strain DH-12 exhibits broad-spectrum antibacterial activity toward Gram-positive and Gram-negative pathogens. The 7.6-Mb draft genome sequence gives insight into the complete secondary metabolite production capacity and reveals genes putatively responsible for its antibacterial activity, as well as genes which enable the survival of the organism in an extreme arid environment.

Amela and Verse are two Streptomyces phages isolated by enrichment on Streptomyces venezuelae (ATCC 10712) from two different soil samples. Amela has a genome length of 49,452, with 75 genes. Verse has a genome length of 49,483, with 75 genes. Both belong to the BD3 subcluster of Actinobacteriophage.

Many pathogenic bacteria secrete $-lactamase enzymes as a mechanism of defence against $-lactam antibiotics. A new Streptomyces sp., NRC-77, was isolated from an Egyptian soil sample. The NRC-77 strain has biochemical, chemotaxonomic, morphological and physiological properties consistent with classification in the genus Streptomyces, with the nearest species being Streptomyces rochei. Furthermo...

Streptomyces sp. strain K30 induces the formation of an extracellular Lcp (latex-clearing protein) during poly(cis-1,4-isoprene) degradation. To investigate the function of this enzyme in Streptomyces sp. strain K30, the lcp gene was disrupted. This was the first time that the screening for a knock out lcp mutant of Streptomyces sp. strain K30 was successful. The resulting mutant Streptomyces s...

Streptomyces colonosanans MUSC 93JT, a novel strain isolated from mangrove forest soil located at Sarawak, Malaysia. The bacterium was noted to be Gram-positive and to form light yellow aerial and vivid yellow substrate mycelium on ISP 2 agar. The polyphasic approach was used to determine the taxonomy of strain MUSC 93JT and the strain showed a range of phylogenetic and chemotaxonomic propertie...

The search for novel bioactive compounds from the natural environment has rapidly been gaining momentum with the increase in multi-drug resistant (MDR) pathogens. In the present study, the antimicrobial potential of novel actinomycetes has been evaluated by initial screening of six soil samples. Primary and secondary screening was performed against Bacillus subtilis, Staphylococcus aureus, Esch...

BACKGROUND Ribosome assembly cofactor RimP is one of the auxiliary proteins required for maturation of the 30S subunit in Escherichia coli. Although RimP in protein synthesis is important, its role in secondary metabolites biosynthesis has not been reported so far. Considering the close relationship between protein synthesis and the production of secondary metabolites, the function of ribosome ...

Five strains of Streptomyces (CAI-17, CAI-68, CAI-78, KAI-26, and KAI-27) were previously reported to have potential for charcoal rot control and plant growth promotion (PGP) in sorghum. In this study, those 5 Streptomyces strains were characterized for their enzymatic activities and evaluated for their PGP capabilities on rice. All the Streptomyces strains were able to produce lipase and β-1,3...

A region of the Streptomyces coelicolor A3(2) chromosome was identified and cloned by using as a probe the lipase gene from Streptomyces exfoliatus M11. The cloned region consisted of 6286 bp, and carried a complete lipase gene, lipA, as well as a gene encoding a transcriptional activator (lipR). The S. coelicolor A3(2) lipA gene encodes a functional extracellular lipase 82% identical to the S....
