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.

A method of producing succinic acid from a biomass, the method comprising:
- adding citric acid to a biomass comprising microalgae to form an acidified microalgae biomass composition;
- storing the acidified microalgae biomass composition under anaerobic conditions without inoculating the acidified microalgae biomass composition with bacteria formulated to produce succinic acid;
- and
- producing a coproduct comprising succinic acid in an amount between 20% on a dry weight basis of a total biomass and 50% on a dry weight basis of the total biomass.
A method of producing succinic acid from a biomass, the method comprising:
- adding between about 1% dry weight basis and about 7% dry weight basis of citric acid to a biomass comprising microalgae to form an acidified microalgae biomass composition;
- 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 in an amount between 20% on a dry weight basis of a total biomass and 50% on a dry weight basis of the total biomass.
