Abstract: A method of producing succinic acid from a biomass. The method comprises adding citric acid to a biomass comprising microalgae to form an acidified microalgae composition. The acidified microalgae biomass composition is stored under anaerobic conditions without inoculating the acidified microalgae composition with bacteria formulated to produce succinic acid. A coproduct comprising succinic acid is produced. Other methods of producing succinic acid from a biomass are also disclosed.

Abstract: A method of preserving a biomass. The method comprises adding an acid solution to a biomass comprising microalgae to form an acidified microalgae biomass composition. The acidified microalgae biomass composition is stored under anaerobic conditions without inoculating the acidified microalgae biomass composition with bacteria. An additional method of preserving a biomass comprises storing the acidified microalgae biomass composition under anaerobic conditions and exposing the acidified microalgae biomass composition to carbon dioxide, nitrogen, or a combination thereof to produce a coproduct comprising succinic acid. Yet another method of preserving a biomass comprises storing the acidified microalgae biomass composition under anaerobic conditions and in the presence of carbon dioxide. A preserved biomass is also disclosed.

Abstract: In some embodiments, the present invention relates to isolated enzymes useful in reducing a fatty acyl-CoA to a corresponding fatty alcohol in a single biosynthetic step, polynucleotides encoding the enzymes, and methods for making and using these polynucleotides and enzymes. In some embodiments, the invention provides for isolated or recombinant enzymes capable of reducing a fatty acyl-CoA to a fatty alcohol. In still another embodiment, the invention provides for isolated or recombinant polynucleotides encoding an enzyme capable of reducing a fatty acyl-CoA to a fatty alcohol. In other embodiments, the invention provides for methods of making or using enzymes capable of reducing fatty acyl-CoA to a fatty alcohol, and methods of making using polynucleotides that encode the enzymes.
