Abstract

An algae cultivation medium includes a growth medium and at least one of an amine additive and a water-soluble biomimetic catalyst. A related method of increasing carbon shuttling in an algae cultivation medium includes adding at least one of the amine additive and the water-soluble biomimetic catalyst to the algae cultivation medium.

First claim

What is claimed:

1 . An algae cultivation medium comprising:
a growth medium; and an amine additive and a water soluble biomimetic catalyst that act together to increase carbon shuttling in an algae cultivation medium.

2 . The algae cultivation medium of claim 1 , wherein said amine additive is a hindered primary amine.

3 . The algae cultivation medium of claim 1 , wherein said amine additive is a hindered secondary amine.

4 . The algae cultivation medium of claim 1 , wherein said amine additive is a tertiary amine.

5 . The algae cultivation medium of claim 1 , wherein said amine additive is an amino acid.

6 . The algae cultivation medium of claim 1 , wherein said biomimetic catalyst is selected from a group of catalysts consisting of

7 . The algae cultivation medium of claim 1 including (a) an amine additive selected from a group consisting of a hindered primary amine, a hindered secondary amine, a tertiary amine, an amino acid and combinations thereof and (b) a water soluble biomimetic catalyst.

8 . The algae cultivation medium of claim 7 , wherein the biomimetic catalyst is selected from a group consisting of

9 . A method of increasing carbon shuttling in an algae cultivation medium, comprising:
adding an amine additive and a biomimetic catalyst to the algae cultivation medium wherein the amine additive and biomimetic catalyst work in concert to increase a concentration of carbon dioxide (CO 2 ) that is bioavailable to the algae.

10 . The method of claim 9 , including using a hindered primary amine as the amine additive.

11 . The method of claim 9 , including using a hindered secondary amine as the amine additive.

12 . The method of claim 9 , including using a tertiary amine as the amine additive.

13 . The method of claim 9 , including using an amino acid as the amine additive.

14 . The method of claim 9 , including using as the biomimetic catalyst a compound selected from a group consisting of

and combinations thereof.

15 . The method of claim 9 , including using a compound selected from a group consisting of a hindered primary amine, a hindered secondary amine, a tertiary amine, an amino acid and combinations thereof as the amine additive in conjunction with the biomimetic catalyst.

16 . The method of claim 15 , including using as the biomimetic catalyst a compound selected from a group consisting of

and combinations thereof.

17 . The method of claim 16 including adding said amine to a concentration of between 0.05 and 1.0 percent by weight and adding said biomimetic catalyst to a concentration of between 0.01 and 0.5 percent by weight.

18 . The method of claim 9 including adding said amine additive to a concentration of between 0.05 and 1.0 percent by weight.

19 . The method of claim 9 including adding said biomimetic catalyst to a concentration of between 0.01 and 0.5 percent by weight.
