TLDR
The results of diversity, antimicrobial activity and enzymes production have increased the scope of finding industrially important marine actinomycetes from the Bay of Bengal and these organisms could be vital sources for the discovery of Industrially useful molecules/enzymes.Abstract:
A total of 288 marine samples were collected from different locations of the Bay of Bengal starting from Pulicat lake to Kanyakumari, and 208 isolates of marine actinomycetes were isolated using starch casein agar medium. The growth pattern, mycelial coloration, production of exopolysaccharides and diffusible pigment and abundance of Streptomyces spp. were documented. Among marine actinomycetes, Streptomyces spp. were present in large proportion (88%). Among 208 marine actinomycetes, 111 isolates exhibited antimicrobial activity against human pathogens, and 151 showed antifungal activity against two plant pathogens. Among 208 isolates, 183, 157, 116, 72 and 68 isolates produced lipase, caseinase, gelatinase, cellulase and amylase, respectively. The results of diversity, antimicrobial activity and enzymes production have increased the scope of finding industrially important marine actinomycetes from the Bay of Bengal and these organisms could be vital sources for the discovery of industrially useful molecules/enzymes.read more

Marine actinomycetes: an ongoing source of novel bioactive metabolites.
TL;DR: The ecological role of actinomycetes in the marine ecosystem is largely neglected and various assumptions meant there was little incentive to isolate marine strains for search and discovery of new drugs, but continued development of improved cultivation methods and molecular technologies for accessing the marine environment promises to provide access to this significant new source of chemical diversity.

TL;DR: In conclusion, Streptomyces bacteria appear to be promising biocontrol agents against a wide range of phytopathogenic fungi, which is not surprising given their ability to produce various bioactive compounds, but further studies on the isolation, formulation and application methods of StrePTomyces along with field experiments are required to establish them as effective biocOntrol agents.

Culturable rare Actinomycetes: diversity, isolation and marine natural product discovery.
TL;DR: It is demonstrated that discovering new compounds with novel scaffolds can be increased by intensive efforts in isolating and screening rare marine genera of Actinomycetes, demonstrating that selective isolation methods are being developed and extensively applied.

An Introduction to Actinobacteria
TL;DR: Though it has various applica‐ tions, some Actinobacteria have its own negative effect against plants, animals, and hu‐ mans, and this chapter summarizes the general characteristics of ActInobacteria, its habitat, systematic classification, various biotechnological applications, and negative impact on plants and animals.

Selection of Media for Isolation of Streptomycetes
TL;DR: In the past, many investigations involving the selective isolation of Streptomycetes from soil have been carried out but there seems little agreement on which media are most suitable for this purpose, so a brief survey of the literature revealed a total of 21 recommended media.

Humic acid-vitamin agar, a new medium for the selective isolation of soil actinomycetes
Masayuki Hayakawa,Hideo Nonomura +1 more
TL;DR: A new medium, designated HV agar, containing soil humic acid as the sole source of carbon and nitrogen was developed and produced remarkably larger numbers of actinomycetes, especially strains of the genera Micromonospora, Microbispora, Streptosporangium, Dactylosporangsium and Saccharomonospora than did glycerol-arginine agar.
