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.

Abstract: A clarification system may comprise a channel having an inlet and an outlet, a length, bottom, and a height sufficient to contain a liquid having a depth. The clarification system may include one or more gas injectors disposed within the channel, configured to inject gas bubbles into a suspension flowing in the channel. In some embodiments, at least one gas injector injects gas bubbles having average or median size that does not exceed 100 microns in diameter. Some gas injectors inject bubbles having mean size below 50 microns. Some gas injectors inject gas via the precipitation of gas bubbles from a supersaturated liquid including a dissolved gas. Certain embodiments may be configured to form a quiet zone, typically near the top of the flowing suspension, in which turbulence may be minimized or substantially eliminated. Certain systems include a plurality of gas injectors disposed at different lengths along the channel.
