BIODIVERSITY OF ACTINOMYCETES AND SECONDARY METABOLITES -A REVIEW
Journal Title: Innoriginal: International Journal Of Sciences - Year 2018, Vol 5, Issue 1
Abstract
Objectives: Actinomycetes are widely distributed in different habitats and involved in important processes.Therefore, evaluation of their distribution is important in understanding their ecological role very different views of actinobacterial diversity emerge from this paper.There are a tremendous diversity and novelty among the marine actinomycetes present in marine environments. Progress has been made to isolate novel actinomycetes from samples collected at different environments and habitats which include soil, rhizosphere soil, hypersaline soil, marine sediments, earthworm casting, goat faeces, desert, caves and honey bee gut. Among microorganisms, actinomycetes are enthralling resource due to their ability to produce novel bioactive secondary metabolites with antimicrobial activities. They have proven to be an inexhaustive mine of antimicrobial agents, especially those potent against pathogenic organisms. Microbial secondary metabolites, especially those from actinomycetes have been a phenomenal success for the discovery of novel drugs. They produce a wide range of secondary metabolites like antibiotics, pigments, enzymes, anti-inflammatory substances and endophenamines and more than 70% of the naturally derived antibiotics are currently in clinical use. Conclusion: They remain a fundamental source of new chemical diversity and an important part of drug discovery. This chapter highlight the bioactive metabolites produces by actinomycetes and their habitats.
