Unexplored hypersaline habitats are sources of novel actinomycetes
Pathogenic microorganisms have evolved sophisticated mechanisms to inactivate antibiotics and rendered an urgent need for new antibiotics that would target the emerging multidrug-resistance (Butler et al., 2013). Consequently, search for novel sources of potent antibiotics is desperately needed to develop potent drugs. Microbial resources have made an incredible contribution to the antibiotic d...
متن کاملDiversity of culturable halophilic sulfur-oxidizing bacteria in hypersaline habitats.
Unexpectedly high culturable diversity of moderately and extremely halophilic obligately chemolithoautotrophic sulfur-oxidizing bacteria (SOB) was discovered in the sediments of various hypersaline habitats, including chloride-sulfate lakes in Mongolia, Russia and Ukraine, a sea saltern in Slovenia and a deep-sea salt brine from the Mediterranean. Six different groups of halophilic SOB, includi...
متن کاملDiscovery of novel metabolites from marine actinomycetes.
Recent findings from culture-dependent and culture-independent methods have demonstrated that indigenous marine actinomycetes exist in the oceans and are widely distributed in different marine ecosystems. There is tremendous diversity and novelty among the marine actinomycetes present in marine environments. Progress has been made to isolate novel actinomycetes from samples collected at differe...
متن کاملNovel method for selective isolation of actinomycetes.
A new technique for the selective isolation of actinomycetes from natural mixed microbial populations is described. A nutrient agar medium was overlaid with a 0.22- to 0.45-microns-pore cellulose ester membrane filter, and the surface of the filter was inoculated. During incubation, the branched mycelia of the actinomycetes penetrated the filter pores to the underlying agar medium, whereas grow...
متن کاملEndophytic Actinomycetes: A Novel Antibiotic Source
Antibiotics are secondary metabolites produced by some microorganisms to inhibit or kill many other microorganisms including different bacteria, viruses and eukaryotic cells. Antibiotics are secondary metabolites and these have also been termed “idiolites” (Walker, 1974). Subsequent and widespread use of antibiotics for therapeutic purposes regularly in human, veterinary and agricultural purpos...
