Abstract

Oil products and a high nitrogen content residue are obtained by growing halophilic algae in saline solution, harvesting an algae-salt water slurry, solvent extracting said slurry, and recovering the product and residue. Use of a growth promoting enzyme, salt concentration gradients for harvesting, and water insoluble solvents at elevated temperatures are preferred.
