actinomycetes are interesting as a main producer of secondary metabolites and industrial antibiotics from marine environments. a total of 44 strains of actinomycetes were isolated from caspian sea sediments at a depth of 5-10 m. preliminary screening was done using cross-streak method against 2 gram-positive and 4 gram-negative pathogen bacteria. the most potent strains mn2, mn3, mn38, mn39, mn...

This review describes the recent research activities in China in relation to studies on antibiotic biosynthetic pathways and pathway engineering in actinomycetes. 75 references are cited.

Problems in the systematics and classification of actinomycetes have attracted many investigators in recent years. Increased interest in the actinomycetes is due to the need for delineating specific antagonistic microorganisms and exploring them as a source of new, desirable antibiotics. As everywhere in biology, the most difficult and complicated, but at the same time most important, aspect of...

Traditionally, filamentous fungi and actinomycetes are well-known cellulolytic microorganisms that have been utilized in the commercial production of cellulase enzyme cocktails for industrial-scale degradation plant biomass. Noticeably, Ktedonobacteria lineage (phylum Chloroflexi) with actinomycetes-like morphology was identified exhibited diverse carbohydrate utilization or abilities. In this ...

Introduction: Marine actinomycetes have a great potential to produce unique bioactive compounds due to their special adaptation in the harsh ocean environment. The current study aimed to isolate anti-cancer compounds producing actinomycetes from sediments of Harra forests of the Persian Gulf and investigate their potential as anti-breast cancer metabolites. Methods: In the current study, 40 se...

Silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. A simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  The present study aimed at the comparative study of silver nanopartic...

Background: Hypersaline solar salterns are extreme environments in many tropical and subtropical regions throughout the world. In India, there are several coastal solar salterns along with the coastal line of the Bay of Bengal and Arabian Sea and inland solar salterns around Sambhar saltlake, from which sodium chloride is obtained for human consumption and industrial needs. Studies on character...

Problem statement: Dermatophytes have developed resistance to the existing antifungal antibiotics. As a part of our continuous search we had isolated, identified and characterized actinomycetes from the halophilic environment having antagonistic activity against the dermatophytes namely Trichophyton, Microsporum and Epidermophyton. Approach: Actinomycetes were isolated from the soil sample coll...
