Method and system for the culture of microalgae
First Claim
1. A method for the culture of microalgae, comprising:
- providing a consortium of at least two living species of microalgae;
culturing under illumination said consortium in a controllable bioreactor and under non-sterile aqueous culture conditions; and
controlling an amount and/or type of nutrients to minimize adhesion of the microalgae to surfaces of the bioreactor without adversely affecting growth of said consortium of microalgae;
wherein controlling the amount and/or type of nutrients consists essentially of providing a combined source of nitrogen-phosphorus-potassium (N—
P—
K).

Abstract
Described is a method for the culture of microalgae, comprising: providing a consortium of at least two living species of microalgae; culturing under illumination the consortium in a controllable bioreactor and under non-sterile aqueous culture conditions; and controlling the culture conditions for affecting at least one of the following output: (i) flocculation and/or settling of said consortium of microalgae; and (ii) adhesion of the microalgae to surfaces of the bioreactor; wherein said culture conditions are controlled to promote (i) and/or to minimize (ii), without adversely affecting growth of the consortium of microalgae. It is also possible to control the culture conditions for affecting iii) the protein, carbohydrate, and/or fat content of the said microalgae consortium. A system for carrying out the method is also described.

24. A method for the culture of microalgae comprising:
-
providing a consortium of at least two living species of microalgae; culturing under illumination said consortium in a controllable bioreactor and under non-sterile aqueous culture conditions; maintaining the culture conditions at a pH between about 6.5 and about 8.5; and controlling a nitrogen concentration in the culture between 0.5 mg/L and 5 mg/L to minimize adhesion of the microalgae to surfaces of the bioreactor, without adversely affecting growth of said consortium of microalgae. - View Dependent Claims (25, 26, 27)
