Abstract: Present study consists seasonal abundance and relationship of actinobacteria with the important chemical characteristics of the marine environment in both water and sediments. Actinobacterial density exhibited clear seasonal variations, being highest (38 × 104 CFU/g dry wt) in monsoon and lowest (13 × 104 CFU/g dry wt) in summer, 2009. Seasonal variations of actinobaterial diversity showed is positive correlation with water nutrients such as phosphate , nitrite, nitrate and silicates and with sediment nutrients such as clay soil, total organic carbon, total nitrogen and total phosphorus. Negative correlation was observed with water temperature, salinity and pH. Monsoon and summer seasons exhibited the major influence on the actinobacterial population in the marine environment of Chennai coast.
