1. A method of fatty acid alkanolamide (FAAA) synthesis and isolation from lipid-containing algal biomass, the method comprising:
reacting the lipid-containing algal biomass with an alkanolamine, an alcohol, or a mixture of alkanolamine and alcohol, with or without catalysts, in a reaction solvent to achieve in situ conversion of fatty acyl donors (FADs) in the lipids to FAAA, fatty acid alkyl esters (FAAE), or a mixture of FAAA and FAAE; recovering the FAAA, FAAE, or mixture of FAAA and FAAE from the reaction medium; and converting any recovered FAAE to FAAA by reacting the recovered FAAE with alkanolamine in a second step.
