Applications of Endophytic Actinomycetes and Their Role in Protection

Abstract

Actinomycetes are one of the most striking sources of antibiotics and other biologically dynamic substances of high viable value. It account approximately for two-thirds of the total known antibiotics isolated from these gram positive, branched spores bearing filamentous group of Eubacteria with notorious bacto-fungoid morphology. Among the actinomycetes, Streptomyces spp. has been the most profuse sources of all types of antibiotics. Screening and isolation of capable strains of actinomycetes with prospective antibiotics is still a thrust area of research and it is recommended that the explorations of resources from new areas and habitat have a key role to play in the search for novel microbes and fresh metabolites and is vital to offset the threats posed by the fast rising occurrence of antibiotic resistance. Counting the endophytic actinomycetes in the race of investigate along the actinomycetes, endophytes have been established to improve and promote growth of swarm plants as well as to decrease disease symptoms caused by plant pathogens and/or various environmental stresses. The low stress tolerance of axenic plants is normally believed to result partially from the deficiency of endophytic actinomycetes. Not only to the plants; they even produces abundant bioactive compounds which are of human being benefit.
