The invention provides a process for producing a fermentable gas stream from a gas source that contains one or more constituent which may be harmful to the fermentation process. To produce the fermentable gas stream, the gas stream is passed through a specifically ordered series of removal modules. The removal modules remove and/or convert various constituents found in the gas stream which may have harmful effects on downstream removal modules and/or inhibitory effects on downstream gas fermenting microorganisms. At least a portion of the fermentable gas stream is preferably capable of being passed to a bioreactor, which contains gas fermenting microorganisms, without inhibiting the fermentation process.

Some aspects of the disclosure are related to systems and methods for controlled oxygen release from biomaterials in vessels and unit operations or components of cell culture, cell containment, and/or bioreactor. Vessels, unit operations, devices, and/or components of the invention may be used to perform all or part of a biological and/or chemical process involving biologicals (e.g., a plurality of cells) in the presence of oxygen-releasing agents. In some embodiments, a system comprises a vessel comprises an oxygen-releasing agent configured to generate in-situ and release oxygen in a sustained manner. The presence of an oxygen-releasing agent may advantageously allow for high cell density fermentation and cell cultivation in a vessel and provide an alternative for supplemental gassing means (e.g., sparger, etc.). Some embodiments of the disclosure are directed to employing the oxygen-releasing agents in microfluidic or millifluidic systems.

The multiport device includes a first flow path configured for withdrawing fluid from the bioreactor, and a second flow path configured for supplying fluid to the bioreactor. The first flow path has a first end adapted to be in fluid connection with the bioreactor, and a second end adapted to be connected to an inlet of the loop. The second flow path has an outer end adapted to be connected to an outlet of the loop, and a mouth adapted to be in fluid connection with the bioreactor. The mouth of the second flow path is distanced from the first end of the first flow path by at least 5 mm, preferably 10 mm.

System and method for providing biocompatible, nutrient filled media to the Human Cells, Tissues, and cellular and tissue-based Products (HCT/P) while removing wastes. The present teachings provide for sensing the characteristics of the media, and modifying the characteristics when necessary. The present teachings can also provide components that can provide fluid pumping integrated with fluid gas exchange, and sensing of fluid characteristics at consistent times during the fluid flow cycle. System and method control multiple bioreactors from a centralized media reservoir, while fluidically isolating the bioreactors from cross-contamination.

A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A tube has a first end and an opposing second end, the first end of the tube being disposed within the compartment of the container. A nozzle is disposed within the compartment of the container and has at least one outlet, the nozzle being coupled with the tube so that a gas can be passed through the tube and out the at least one outlet of the nozzle. The nozzle is sufficiently buoyant so that when a fluid is disposed within the compartment of the container, the nozzle floats on the fluid.
