The invention provides for the integration of a CO-consuming process, such as a gas fermentation process, with a COelectrolysis process. The invention is capable of utilizing a CO-comprising gaseous substrate generated by an industrial process and provides for one or more removal modules to remove at least one constituent from a CO-comprising gaseous substrate prior to passage of the gaseous substrate to a COelectrolysis module. The invention may further comprise one or more pressure modules, one or more COconcentration modules, one or more Oseparation modules, and/or an Helectrolysis module. Carbon conversion efficiency is increased by recycling COproduced by a CO-consuming process to the COelectrolysis process.

Process for improving carbon conversion efficiency

The systems and methods disclosed herein provide for the efficient generation of fine bubbles. In particular, systems and methods for use in bioreactors are disclosed herein providing a superior means to produce useful fermentation products by the biological fermentation of fine bubble waste substrates injected into a liquid broth containing a microorganism culture.

System and method for generating bubbles in a vessel

A reactor system is provided for improved fermentation of a gaseous substrate through the introduction of a secondary loop to a forced-circulation loop reactor. The reactor comprises a primary loop through which fermentation broth comprising a gaseous substrate is circulated through a riser segment and a downcomer section by a loop pump. Downstream of the loop pump a portion of fermentation broth is withdrawn from the downcomer section and is directed to the top of the reactor via a secondary loop. Further provided is a method for improving the mass transfer of a gaseous substrate to a fermentation broth in a fermentation vessel comprising a secondary loop. Further provided is a method for reducing foam in the headspace of a fermentation vessel comprising a secondary loop.

Fermentation of gaseous substrates

The invention provides a microbubble generation system with increased efficiency and flexibility compared to known systems. Further, the invention provides a method of microbubble generation. In particular, invention relates to increasing the efficiency of a fermentation reaction by reducing bubble size and increasing gas absorption into a liquid fermentation broth.
