A study on actinomycetes population and physico chemical properties of shore line soil from selected coastal areas of tamil nadu

Shore line soil samples were collected from twelve different coastal areas of Tamil Nadu and tested by dilution plating technique on Starch casein and Kuster’s agar medium to assess the actinomycetes diversity. Physico chemical characteristics of the soil such as pH, temperature, electrical conductivity, salinity, total dissolved solids, moisture content, water holding capacity, carbon, nitrogen, hydrogen and sulfur content were analyzed to find out the impact on actinomycetes population. A total number of 376 actinomycetes were recorded from all the shoreline soil samples. Physico chemical analysis revealed the variations of parameters in each sampling sites. Correlation analysis made between physico chemical properties of shore line soil and actinomycetes population revealed no factor as accountable for the actinomycetes population changes in different sampling sites. Multivariate cluster analysis statistical technique was applied to evaluate the variations in shore line soil quality of different sampling sites.
