The present invention is directed to a process for obtaining a lipid from a composition comprising microbial cells, the process comprising: treating the composition comprising microbial cells to a temperature of about 60° C. to about 95° C. at a pH of about 9 to about 11; separating the treated microbial cells into a light phase and a heavy phase; sequentially, in one or more cycles, raising the pH of the concentrated microbial cell composition to 10 or above, followed by lowering the pH of the concentrated microbial cell composition to a pH of less than 6 to lyse the concentrated microbial cell composition, wherein the raising and lowering of the pH also demulsifies the concentrated microbial cell composition; separating the lipid from the demulsified cell composition, and recovering the lipid.

A method and apparatus for extracting botanical oil from botanical mass includes milling the biomass and chilling the milled biomass. The biomass is then exposed to a chilled ethanol solvent. Water is added and the solution introduced into a first centrifuge. The clean ethanol slurry is then introduced into an evaporator leaving a two-phase mixture which is introduced into a second centrifuge which separates the water from the pure botanical oil.

A method for purification and extraction of cannabinoids includes: providing a cannabis oil including phospholipids and cannabinoid acids; contacting the cannabis oil with a degumming solvent, wherein the degumming solvent and cannabis oil are substantially immiscible; and separating an aqueous phase including the degumming solvent and at least a portion of the phospholipids from an oil phase including the cannabis oil. The method may further include contacting the oil phase with an extraction solvent, where the extraction solvent and oil phase are substantially immiscible; and separating an aqueous phase including the extraction solvent and at least a portion of the cannabinoid acids from a second oil solvent phase including the oil phase and/or simply the liberated cannabinoids following acidification of the extraction solvent.
