23 Sep Harnessing Actinomycetes for organic farming and agriculture sustainability
Actinomycetes are widely recognized for significant role in promoting soil health and sustainable agriculture through the production of diverse bioactive compounds and plant growth promoting metabolites. This article highlights the ecological significance and agricultural importance of actinomycetes, with particular emphasis on their ability to produce antibiotics, extracellular enzymes, siderophores, and phytohormones. It also discusses their contributions to nutrient solubilization and mobilization, and enhancement of plant stress tolerance, biocontrol of pathogens and improvement of soil quality through bioremediation. Additionaly, the article explores the application of Actinomycetes as biofertilizers and bioinoculants in organic farming, emphasizing their potential to increase crop productivity while reducing dependence on chemical fertilizers and pesticides. Actinomycetes represent a promising and eco-friendly resource for improving soil fertility plant health, and the long-term sustainability of organic agriculture systems 1. Introduction to Actinomycetes Actinomycetes are Gram-positive, filamentous prokaryotic microorganisms belonging to the phylum Actinomycetota (Actinobacteria). Although they are classified as bacteria, they possess distinctive morphological and physiological characteristics that differentiate them from other bacterial groups. They are ubiquitous in terrestrial and aquatic ecosystems and are particularly abundant in soils with neutral to alkaline pH, high temperatures, or limited moisture availability, where they play a crucial role in maintaining soil health and ecological balance. Morphologically, actinomycetes exhibit a fungus-like growth pattern by producing extensively branched...
