摘要: Marine actinobacteria are the most economically as well biotechnologically valuable prokaryotes. Representative genera of marine include Actinomadura, Aeromicrobium, Dietzia, Gordonia, Marinophilus, Micromonospora, Nonomuraea, Rhodococcus, Saccharomonospora, Saccharopolyspora, Salinispora, Streptomyces, Solwaraspora, Williamsia, Verrucosispora and several others. Among actinobacteria, genus Streptomyces is represented in nature by largest number species varieties, which differ greatly their morphology, physiology, biochemical activities. occur different biological sources such fishes, molluscs, sponges, seaweeds mangroves, besides seawater sediments. In this review an evaluation made on present state research its perspectives. The highlights production metabolites antibiotics, anticancer compounds, enzymes, enzyme inhibitors pigments application single cell protein probiotics aquaculture. environment contains a wide range distinct that not terrestrial environment. With increasing advancement science technology, there would be greater demands future for new bioactive compounds synthesised from various sources.
