NOVELTY - Extracting (100) lipids from microalgae, comprises: pretreating (25) a quantity of generally non-homogenized microalgae with an aliphatic alcohol for a predetermined time for liberating lipids from the microalgae; separately (35) treating the liberated lipids with a transesterification reagent to form fatty acid methyl esters within a resulting mixture; and separating (45) the fatty acid methyl esters from the resulting mixture.    USE - The process is useful for extracting lipids from microalgae derived from at least one of domestic, municipal and agricultural wastewater, to produce biodiesel product (all claimed) and glycerol.    ADVANTAGE - The process: utilizing pretreatment, which liberates a substantial portion of lipids from microalgae without requiring energy intensive cell membrane disruptive technologies and/or use of highly toxic chemical solvents (e.g. chloroform); provides fatty acid methyl esters, which is a renewable green energy biodiesel product which does not increases carbon dioxide emissions; is commercially viable; and minimizes hydrolysis reactions when basic transesterification processes are utilized.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) extracting (I) lipids from microalgae, comprising pretreating a quantity of non-homogenized microalgae with 2-propanol for 0.25-4 hours to liberate lipids from the microalgae to form a first mixture, separating the liberated lipids from the first mixture with a biphasic solvent, treating the separated liberated lipids with a transesterification reagent to form fatty acid methyl esters in a second mixture, and separating the fatty acid methyl esters from the second mixture; and    (2) biodiesel product formed by the processes.
