A method for reducing the free fatty acid content of a feedstock includes the steps of providing a free-fatty-acid-containing feedstock, treating the free-fatty-acid-containing feedstock to reduce the free fatty acid content thereof, where the step of treating includes combining at least one of an algae and a coagulant to the free-fatty-acid-containing feedstock, and producing a product from the treated feedstock. 1. A method for reducing the free fatty acid content of a feedstock comprising the steps ofcombining algae with a medium to form an algae-containing medium,combining a free-fatty-acid-containing feedstock with the algae-containing medium to form an algae treatment feedstock,allowing the algae to reduce the free-fatty-acid content of the algae treatment feedstock, and, after said step of allowing,producing a product from the algae treatment feedstock.2. The method of claim 1 , wherein the medium comprises water claim 1 , the method further comprising the steps ofagitating the algae treatment feedstock to form an upper oil phase, a lower aqueous phase, and a middle phase andcollecting said upper oil phase.3. The method of claim 2 , wherein the collected upper oil phase has a lower free fatty acid content than the free-fatty-acid-containing feedstock.4. The method of claim 2 , wherein the collected upper oil phase has a lower acid value than the free-fatty-acid-containing feedstock.5. The method of claim 1 , wherein the medium comprises water and waste cooking oil.6. The method of claim 1 , wherein the medium comprises a mineral medium.7. The method of claim 6 , wherein the mineral medium comprises one or more of the following components: glucose claim 6 , MgCO claim 6 , NHCl claim 6 , KHPO claim 6 , nitrilotriacetic acid claim 6 , peptone claim 6 , MgSO.7HO claim 6 , yeast extract claim 6 , CaCO claim 6 , NaEDTA claim 6 , FeCl.6HO claim 6 , HBO claim 6 , thiamine claim 6 , MnCl.4HO claim 6 , ZnSO.7HO claim 6 , CoCl claim 6 , 6HO claim 6 , NaMoO.2HO and ...
