NOVELTY - Algae comprising lipids, and proteins, where the algae are heterotrophic and evolutionarily modified (EMO) to process raw glycerol as a primary carbon source, are new.    USE - The algae are useful for processing raw glycerol; and for producing biodiesel product from by-product of biodiesel production (all claimed).    ADVANTAGE - The microorganisms (e.g. algae and bacteria) utilized by the invention may be evolutionarily modified to serve as an improved source of biofuel, biodiesel, and other hydrocarbon products.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a method for processing raw glycerol comprising obtaining a first raw glycerol fraction; and processing the first raw glycerol fraction by growing the algae with the first raw glycerol fraction as a primary carbon source;    (2) a raw glycerol processing site comprising a culture unit for growing EMO algae that process raw glycerol as a primary carbon source, the culture unit comprising the algae and raw glycerol;    (3) a biodiesel manufacturing site comprising: (i) a reactor unit for transesterifying a first lipid fraction with an alcohol to obtain alkyl esters and a raw glycerol fraction; (ii) a separator unit to separate the alkyl esters from the raw glycerol fraction; (iii) a culture unit for growing evolutionary modified (EMO) algae that utilizes the raw glycerol fraction as a primary carbon source, the culture unit comprising the algae and raw glycerol fraction; (iv) an algae processing unit for processing the algae grown in the culture unit to obtain a second lipid fraction; and (v) a return unit for sending the second lipid fraction to the reactor unit; and    (4) a method for producing a biodiesel product from a by-product of biodiesel production, comprising obtaining a by-product of biodiesel production, the by-product of biodiesel production comprising raw glycerol; growing the algae with the byproduct of biodiesel production, and where the raw glycerol is the primary carbon source; isolating and recovering the algae from the growing step; fractionating the algae from the growing step to obtain a first lipid fraction; transesterifying the first lipid fraction with an alcohol to obtain alkyl esters as the biodiesel product and a second by-product of biodiesel production comprising raw glycerol; and recovering the biodiesel product, and optionally other hydrocarbon products, fatty acids products, and proteins.
