Abstract

Disclosed herein are methods and processes for the recovery of oleaginous compounds from biomass, in particular biomass comprises photosynthetic microorganisms and oleaginous compositions obtained using the disclosed methods. The method for obtaining an oleaginous composition from biomass comprises the following steps: (a) obtaining an feedstock comprising said biomass and water; (b) heating the feedstock in a closed reaction vessel to a first temperature between about 250°C and about 360°C and holding at said first temperature for a time between 0 minutes and about 90 minutes (c) cooling the feedstock of (b) to a temperature between ambient temperature and about 150°C; (d) acidifying the cooled feedstock of (c) to a pH from about 3.0 to less than 6.0 to produce an acidified composition; (e) heating the acidified composition of (d) to a second temperature of between about 40°C and about 150°C and holding the acidified composition at said second temperature for between 0 minutes and about 45 minutes; (f) separating the acidified composition into at least an organic phase and an aqueous phase; and (g) removing the organic phase from said aqueous phase to obtain an oleaginous composition.
