Effect of oil spill on the microbial population in Andaman Sea around Nicobar Island
Abstract
The microbial studiees of the follow up cruise by FORV Sagar Sampada (cruise No. 113), 9 months after the oil spill in the Andaman Sea due to accident of VLCC Maersk Navigator revealed disturbance in the natural microbial population. Higher abundance of heterotrophic microorganisms was observed at several coastal stations as well as from greater depths. Oelophilic microorganisms were fairly abundant at some of the stations especially st. 2991 at 400 m and 500 m depths. The presence of oelophilic microorganisms at different stations and greater depths could be indicative of the remanant of the oil spill.
