Actinomycetes are abundantly present in soil and they produce a variety of antimicrobial compounds that can be used as chemotherapeutic agent in order to limit the infection. In present study, Actinomycetes were isolated from soil and vermicompost samples collected from the Guntur district, Andhra Pradesh, India. Total 93 isolates were isolated from soil and vermicompost samples. Isolates were identified by colony characterizations, microscopy and biochemical tests. Out of the 93 isolates six isolates are shown six streptomyces sp ESS-4 (Streptomyces fradiae), DVS-11 (Streptomyces olivoviridis), KZSS-6 (Streptomyces koyangensis), NVS-10 (Streptomyces flavofuscus), TSS-3 (Streptomyces griseorubens), and TVS-2 (Streptomyces lunaelactis) were previously reported to antagonistic activity in fungal pathogens, Plant Growth Promoting traits, Greenhouse and field conditions in black gram, antibacterial activity, antibiotic resistances, and optimization of pH, salinity, temperature, carbon sources, and heavy metals. Microorganisms, extracts of botanicals and secondary metabolites of microorganisms are commonly used as bio-pesticides. Primarily these isolates were screened for intercellular metabolites production by conventional methods. Actinomycetes will be screened against fungal pathogens. Culture filtrates of the most promising Actinomycetes will be evaluated for their effectivity. Compounds from the filtrate will be identified and isolated by using various chromatographic techniques
