Abstract

A method of exposing microorganisms to a condition wherein the condition facilitates or inhibits growth of a specific species of microorganisms or a specific consortium of microorganisms. The condition may also stimulate microorganisms to uptake a pollutant from a fluid and/or release the pollutant. Furthermore, the microorganisms may also be harvested and used as a foodstuff for human and animal consumption.

Claims (33)

1. A method of facilitating or inhibiting growth of a species or consortium of microorganisms, the method comprising:

providing a growing apparatus having a first reservoir containing a first fluid, and a second reservoir containing a second fluid, and at least one moving belt operably configured to directly travel through both the first fluid and the second fluid;

growing microorganisms using the growing apparatus;

exposing the microorganisms to the first fluid within the first reservoir, wherein the microorganisms are exposed to a first condition;

exposing the microorganisms to light and air outside of the first reservoir; and

exposing the microorganisms to the second fluid, wherein the microorganisms are exposed to a second condition;

wherein one or more of the first condition or the second condition:

facilitates growth of a desirable species or consortium of microorganisms, or

inhibits growth of an undesirable species or consortium of microorganisms.

2. The method of claim 1 , wherein the first fluid contains a pollutant, the first condition stimulates the microorganisms to uptake the pollutant from the first fluid, and the second condition stimulates the microorganisms to release the pollutant.

3. The method of claim 1 , further comprising, after exposing the microorganisms to the second fluid, exposing the microorganisms to the first fluid again.

4. The method of claim 1 , wherein the at least one moving belt comprises a coating.

5. The method of claim 1 , wherein the at least one moving belt moves in a continuous manner.

6. The method of claim 1 , wherein the microorganisms are algae, bacteria, fungi, or a combination thereof.

7. The method of claim 1 , wherein the second condition is an elevated temperature compared to the first condition.

8. The method of claim 1 , wherein the second condition is an elevated temperature within a range of 30-90 degrees Celsius.

9. The method of claim 1 , wherein the second condition is an illumination using increased light intensity.

10. The method of claim 1 , wherein the second condition is exposure to a sorbent material.

11. The method of claim 1 , wherein the second condition is radiation.

12. The method of claim 1 , wherein the second condition is an elevated pH compared to the first condition.

13. The method of claim 1 , wherein the second condition is a salt.

14. The method of claim 1 , wherein the second condition is an organic chemical.

15. The method of claim 14 , wherein the organic chemical is not present in the first fluid.

16. The method of claim 1 , wherein the second condition is an inorganic chemical.

17. The method of claim 1 , wherein the second condition includes hormones.

18. The method of claim 1 , wherein the second condition includes growth stimulants.

19. The method of claim 1 , wherein the second condition includes antimicrobials.

20. The method of claim 1 , further comprising harvesting the microorganisms.

21. The method of claim 1 , wherein the growing apparatus further comprises a third reservoir containing a third fluid, the method further comprising:

exposing the microorganisms to the third fluid, wherein the microorganisms are exposed to a third condition,

wherein one or more of the first condition, the second condition, or the third condition:

facilitates growth of the desirable species or consortium of microorganisms, or

inhibits growth of the undesirable species or consortium of microorganisms.
