Efficient Light Harvesting
First Claim
1. A method for selecting a photosynthetic organism, the method comprising:
- choosing a first photosynthetic organism having a first transparency associated with light transmission through the first photosynthetic organism;
subjecting the first photosynthetic organism to mutagenesis to create one or more second photosynthetic organisms;
determining a second transparency associated with light transmission through at least one of the second photosynthetic organisms; and
selecting one or more second photosynthetic organisms for which the second transparency is greater than the first transparency.

Abstract
Various aspects provide for genetically modifying photosynthetic cells. In some cases, an integrated light harvesting efficiency of photosynthetic cells may be increased by reducing the amount of incident light that is absorbed but not used for photosynthesis. In some cases, an increased transparency may be associated with an increased light harvesting efficiency when absorption due to non-photosynthetic processes is reduced. A reduced capacity of various light-harvesting antenna apparatus may increase transparency. In some cases, a capacity of an organism to adapt to varying light levels may be reduced, and in certain cases, a modified organism may have a reduced ability to acclimate to a low light irradiance.

17. A method of increasing a light harvesting efficiency of a photosynthetic organism, the method comprising:
-
selecting a first photosynthetic organism; subjecting the first photosynthetic organism to mutagenesis to create one or more second photosynthetic organisms; determining a first sensitivity associated with a light harvesting apparatus of the first photosynthetic organism; determining a second sensitivity associated with a light harvesting apparatus of at least one second photosynthetic organism; and selecting a second photosynthetic organism for which the second sensitivity is less than the first sensitivity. - View Dependent Claims (18, 19, 20, 21)

22. A plurality of genetically modified photosynthetic cells, the plurality having:
-
a greater transparency than a substantially equivalent plurality of non-genetically modified versions of the photosynthetic cells; and a greater integrated growth rate than that of a substantially equivalent plurality of non-genetically modified versions of the photosynthetic cells. - View Dependent Claims (23, 24, 25, 26, 27)
