The marine environment represents a largely untapped source for isolation of new microorganisms with potential to produce biologically active secondary metabolites. Among such microorganisms, Gram-positive actinomycete bacteria are of special interest, since they are known to produce chemically diverse compounds with a wide range of biological activities. We have set out to isolate and characte...

A large number of microbes existed in animal feces. To provide new sources for discovering new leader of drugs, the diversity of cultivable actinobacteria of animal feces have been studied. Fresh fecal samples of 6 species of herbivore feces were collected. The pure cultures of actinobacteria were isolated from these samples by using 5 media. The 16S rDNA gene sequences of 386 selected strains ...

Andaman and Nicobar Islands, considered as one of the important marine ecosystem in India and being considered as the richest source for microbial community. The marine microbial taxa and actinomycetes diversity are not been fully explored. Actinomycetes were isolated from marine soil samples and screened for antibacterial activity. Out of eight isolates, the isolate AN1 isolated from soil samp...

The structure of the Bacteria and Archaea community in a large drinking water reservoir (Marathonas, Greece; MR) was investigated in October 2007 and September 2008, using 16S rRNA gene clone libraries. The bacterial communities were more diverse than archaeal communities (Shannon diversity index H' 0.81-3.28 and 1.36-1.77, respectively). The overall bacterial community composition was comparab...

We used terminal restriction fragment length polymorphism (T-RFLP), clone library, phylogenetic, and bulk nucleic acid hybridization analyses to identify and characterize spatial and temporal patterns in marine bacterioplankton communities at the Bermuda Atlantic Time-series Study (BATS) site. Nonmetric multidimensional scaling of monthly surface and 200-m bacterial 16S rDNA T-RFLP fragments fr...

Actinomycetes are a diverse group of medically, industrially and ecologically important bacteria, studied as much for the diseases they cause as for the cures they hold. Along with also as a source of industrial important product which are helpful for mankind. However, many of the rare genera of actinomycetes have been neither explored nor manipulated for their biotechnological and industrial p...
