Abstract :
The successful yield of oil from micro algae is dependent upon combined interaction of physical, chemical and biological factors. Selected marine Bacillariophyceans were studied for the yield of oil in relation to various physical, chemical and biological parameters. The optimum pH, salinity, temperature, phosphate, nitrate and silicate required for the maximum growth and oil yield are found to be varied from species to species. Silicate, being one of the most important components for diatoms, it is observed to increase oil yield most favourably at zero level even though it could decrease the biomass production. Amongst the different harvest methods tested, the centrifugation has yielded more oil. The Pseudomonas sp inoculated algae has increased the oil yield. Significantly intra generic varied species has shown variation in oil yield but a particular species collected in different location also has shown variation in oil yield under similar culture conditions. Different light intensities and duration of light have been observed to affect the oil yield of Bacillariophyceae.
