Abstract: The microorganism-containing biocatalysts disclosed have a large population of the microorganisms irreversibly retained in the interior of the biocatalysts. The biocatalysts possess a surprisingly stable population of microorganisms and have an essential absence of debris generation from metabolic activity of the microorganisms. The biocatalysts are composed of highly hydrophilic polymer and have an internal, open, porous structure that promotes community phenotypic changes.

Abstract: Bioconversion processes are disclosed in which biocatalysts including microorganisms or isolated enzymes that are substantially irreversibly retained in the interior of an open, porous, highly hydrophilic polymer are cycled between at least two different fluid media for the bioconversion of one or more substrates to one or more bioproducts. The processes are particularly attractive for using gas phase or using liquid feedstocks containing the substrate.

Abstract: Bioconversion processes are disclosed in which two or more biocatalysts including microorganisms or isolated enzymes that are substantially irreversibly retained in the interior of an open, porous, highly hydrophilic polymer are used in a common aqueous medium. In one exemplary embodiment, one biocatalyst produces a chemical product that is a substrate to at least one other biocatalyst. In another exemplary embodiment, the feed includes two or more substrates and one biocatalyst bioconverts at least one substrate and another biocatalyst bioconverts at least one other substrate. This aspect is particularly useful for treating water including disparate contaminants by metabolic degradation in a bioreaction zone including multiple types of biocatalysts.

Abstract: Processes are disclosed for bioconversion processes in which a ME biocatalyst is surrounded by water-insoluble liquid during the bioconversion to facilitate one or more of mass transfer of substrate to and bioproduct from the biocatalyst and the separation and recovery of bioproduct from the water-insoluble liquid. The ME biocatalyst irreversibly retains microorganizms for the bioconversion and has, in its interior, an aqueous environment.
