  • ALGAE PRODUCTION TRIALS AT ENERGYMICROLGAE Algae production trials with out any organic or inorganic C input Sea water filled in 10 m2 RCC tanks at a depth of 50 cm. Time: 7 AM
  • The media was fertilized and inoculated with Phaeodactylum sp. 8 AM
  • Density of cells by 5 PM same day
  • Algae just before harvest 6 PM next day
  • The algae harvested after 32 hrs by 6 PM next day. Dry paste of > 10 Kg obtained from three 10 m2 tanks.
  • Dry algae biomass (< 10% moisture) of 1.5 Kg from 30 m2 area. 25 g/m2/day. The production cost found to be less than Rs.4 (US$ 0.087) per Kg of algae biomass. The lipid content of the biomass is estimated as 20 %. The trials were repeated several times and the production figures were consistent with insignificant variations.
  • Cost analysis (costs as % of $0.09) Pond and water supply : 13 Harvesting : 5 Other infra : 2 Fertilizer : 19 Energy : 37 Manpower : 16 Interest( Capital + Land cost) : 7 Taxes and ancillary : 1 http://www.energymicrolgae.com
