| Abstract: | Effect of Bombay high crude oil (BHC) and its water-soluble fraction (WSF) on growth and metabolism of the phytoplankton, Thalassiosira sp. was assessed. The study revealed the signs of acute toxicity at higher concentrations of crude oil (0.5%) and WSF (40%), while stimulatory effect was observed at lower concentrations (0.01 and 0.1% of BHC and 5, 10% of WSF). WSF at higher concentrations (20 and 40%) caused reduction in DNA and RNA of the diatom. At lower concentrations it caused increase in protein and RNA content indicating increased metabolism. High concentrations of oil and its fraction had inhibitory effect on growth, protein content and nucleic acid content. This indicates that biosynthesis of these molecules may be probable targets for toxicity of oil. |
