Abstract

Methods are provided for pelletizing a microbial biomass, extracting a refined lipid composition from the pelletized biomass under supercritical conditions and distilling the refined lipid composition, at least once under short path distillation conditions, to obtain a lipid-containing fraction. Also disclosed are methods of making lipid-containing oil concentrates therefrom, by transesterifying and enriching the lipid-containing fraction.
