Abstract: PFRs for running multiphasic processes are disclosed. The PFRs are single or multi-chamber devices having at least three types of regions (a liquid-contacting region, a gas-contacting region and a Ssquid-coSection region), and a porous substrate providing fluid communication at least between the liquid-contacting and gas-contacting regions. Removal of liquid from the porous substrate, such as by collecting the liquid as it flows off the bottom of the porous substrate in the Siquid-coSSection region or such as by evaporation of the liquid from the porous substrate in the evaporation region supports a continuous flow process. Methods of using the PFRs are also disclosed, for example methods of using the PFRs as photobioreactors for cultivating photosynthetic microorganisms, for producing fermentable sugars, for producing ethanol, for fermenting synthesis gas and producing single cell protein from natural gas.

Abstract: The disclosure describes Structured Biological Materials (“SBM”) adapted for use in emulsion-less multiphasic processes. The SBM is a substratum-microbial matrix combination, wherein the microbial matrix houses one or more natural or genetically-engineered microorganisms capable of catalyzing or performing reactions that occur in multiphasic environments. When used in an emulsion-less system, the SBMs should be able to maintain separation of the bulk phases sufficient to maintain the emulsion-less nature of the system. The disclosure also provides methods of using the SBMs, for example in performance of multiphasic reactions, such as emulsion-less biphasic liquid/liquid reactions. This disclosure also provides multiphasic membrane reactors wherein an SBM functions as the membrane, such as emulsion-less biphasic reactors wherein an SBM functions as the biphasic membrane.
