Beneficial microorganisms provide first line defense for roots against diseases and promote plant growth. Actinomycetes in vermicompost aid in the breakdown of organic materials and the production of secondary metabolites. In the present investigation, actinomycetes were isolated from vermicompost prepared using Arachis hypogeal. Scanning electron microscope (SEM) images were used to study the morphological changes in actinomycetes. The SEM images revealed various stages of mycelia growth of the Streptomyces sp. during the growth period. Identification of bioactive compounds produced by Streptomyces sp. were analyzed through Gas Chromatography-Mass Spectrometer (GC-MS) the result revealed the presence of twenty major bioactive compounds, among them, Cetane, E-15-Heptadecenal and n-Hexadecanoic acid which are important for plant growth and disease suppression. Hence, actinomycetes established in vermicompost can be used for plant growth promotion, suppression of pathogens and synergistic interaction with other beneficial soil microorganisms.
