Totally 189
Streptomyces
isolates were obtained from eight different soils of
Cuddalore, Tamil Nadu, India. Among them, only 78 isolates were morphologically
distinct. The highest diversity in the
Streptomyces populations was observed in
agricultural soil with minimum occurrence of antagonistic organisms. The least
number of
Streptomyces strains was found in coastal soil with maximum
antagonistic organisms. A connection between physicochemical properties of the
soil and the
Streptomyces abundance was established. There was a positive
correlation between the total
Streptomyces population and nitrogen, available
phosphorus, ferrous and manganese, while the correlation with pH and sodium was
negative. This study clearly revealed the occurrence of
Streptomyces spp. and its
correlation with the available nutrient in the environment.
