This study investigates the quantitative and qualitative characteristics of indigenous microorganisms present in soil and water sources within the industrial zone of the Shargun coal mine in Surkhandarya region. Physiological and enzymatic activities, metabolic adaptability, and carbon-assimilation capacities of the isolated strains were evaluated in nutrient media containing coal as the sole carbon source. Bacillus simplex, Bacillus subtilis, and Pseudomonas fluorescens demonstrated high growth rates, substantial protein synthesis, and notable hydrolytic activity towards complex substrates (starch, cellulose, tannin). These findings indicate that the isolated strains can be effectively employed for bioindication and bioremediation of soils contaminated with coal and coal-derived waste in industrial areas.
