High productivity bioprocesses for the massively scalable and ultra-high throughput conversion of co2 into valuable products

A system for mixing a liquid with a gas, comprising:

• a. a bioreactor comprising the liquid and the gas, wherein the gas comprises collected gas separated from the liquid;
• and
• b. a gas entrainment impellor comprising an upper end, a lower end, a gas conduit, and radial blades, wherein the upper end extends into the gas, the lower end extends into the liquid, the gas conduit connects the upper end and the lower end, wherein the radial blades are within the liquid, and
• wherein, upon rotation of the radial blades, the system is configured to:
• (i) generate a suction to cause the collected gas to flow from the liquid to the gas through the gas conduit;
• (ii) cause the gas to flow from the upper end to the lower end;
• and
• (iii) mix the liquid and the collected gas.

A method for recycling gas in a bioreactor, the method comprising:

• collecting gas separated from a liquid within a bioreactor system, wherein the bioreactor system comprises:
• a. a bioreactor comprising a liquid and a gas, wherein the gas comprises collected gas separated from the liquid;
• and
• b. a gas entrainment impellor comprising an upper end, a lower end, a gas conduit, and radial blades, wherein the upper end extends into the gas, the lower end extends into the liquid, and the gas conduit connects the upper end and the lower end, wherein the radial blades are within the liquid, and wherein, upon rotation of the radial blades, the system is configured to:
• (i) generate a suction to cause the collected gas to flow from the liquid to the gas through the gas conduit;
• (ii) cause the gas to flow from the upper end to the lower end;
• and
• (iii) mix the liquid and the collected gas.
