Abstract
Actinomycetes, a varied genus of filamentous bacteria, play an important role in
soil ecosystems, especially in limestone-derived soil. This research looks at the
effect of soil physicochemical qualities on the diversity and biochemical characteristics
of actinomycetes isolated from limestone-rich settings. Soil samples were tested
for pH, moisture content, organic matter and key nutrients to determine their impact
on microbial diversity. Actinomycetes were isolated, identified and described by
using morphological and biochemical methods preliminarily.
The data show that alkaline pH, calcium-rich composition and organic matter all
have a substantial impact on actinomycete variety and metabolic capacities, especially
antibiotic synthesis and enzymatic activity with intricate biosynthetic pathways.
These findings emphasize the ecological importance of soil characteristics in creating
microbial communities and their potential for biotechnological applications.
