ABSTRACT
This study investigates the distribution of actinobacteria in different soil samples from the Kalaburagi region, focusing on the relationship between their prevalence and the physicochemical and elemental properties of the soil. Soil samples were analyzed for key parameters, including pH, moisture content, inorganic carbon, nitrogen and elemental composition to understand the factor influencing microbial diversity. The results revealed significant variations in soil physicochemical properties across different locations, with high levels of inorganic carbon and nitrogen correlating with increased actinobacteria presence. Additionally, 48 actinomycetes were isolated based on their morphological characteristics, demonstrating the adaptability of these microorganisms to diverse soil conditions. The findings highlight the role of soil physicochemical properties in shaping microbial communities and emphasize the kalaburgi region potential as a rich reservoir of actinobacteria. These microorganisms hold promise for applications in biotechnological and agriculture.
