BACKGROUND Filamentous bacteria of the genus Streptomyces produce a large arsenal of industrially relevant antibiotics and enzymes. The industrial production of these molecules occurs in large fermenters, where many streptomycetes form dense mycelial networks called pellets. Pellets are characterized by slow growth and inefficient nutrient transfer and therefore regarded as undesirable from the...

This study reports the isolation of novel Bacterium from Soil for production of Extra-cellular Laccase Enzyme. Samples from garden, ant-induced and animal dung contaminated soil were collected in the Devi Ahilya University campus and around, Indore, Madhya Pradesh. Various methods including biochemical and morphological identification for high productivity of the enzyme were used. The media opt...

Symbiotic associations between different organisms are of great importance for evolutionary and ecological processes [1-4]. Bacteria are particularly valuable symbiotic partners owing to their huge diversity of biochemical pathways that may open entirely new ecological niches for higher organisms [1-3]. Here, we report on a unique association between a new Streptomyces species and a solitary hu...

Background: Endophytic non-streptomycetes group of actinomycetes from Hibiscus rosasinensis leaves were screened for biosurfactant, polythene, plastic, and diesel biodegradation activities. Biosurfactant activity was evaluated by hemolysis, drop-collapsing test, lipase production, oil-spreading technique, bacterial adhesion to hydrocarbon (BATH) assay, penetration assay, and emulsification assa...

In the era when large whole genome bacterial datasets are generated routinely, rapid and accurate molecular systematics is becoming increasingly important. However, 16S ribosomal RNA sequencing does not always offer sufficient resolution to discriminate between closely related genera. The SsgA-like proteins are developmental regulatory proteins in sporulating actinomycetes, whereby SsgB activel...

Transduction was mediated by a 8-kb segment of bacteriophage FP43 DNAcloned into plasmid pIJ702: The resulting plasmid, pRHBlOl, was packaged in bacteriophage heads as linear concatemers and was transduced into about 80% of the Streptomyces species tested1}. We showed that the efficiency of transduction can vary markedly depending on the cell growth conditions, and that under optimum growth con...
