Patents Assigned to Microvi Biotech, Inc.
  • Patent number: 10752528
    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.

  • Patent number: 10584047
    Abstract: Processes are disclosed for the microbial nitritation of ammonia that attenuate the production of at least one of nitrate anion and nitrous oxide. The processes use an ME biocatalyst having a highly porous, hydrophilic polymeric structure with ammonia-oxidizing microorganisms substantially irreversibly retained therein. The processes are particularly useful for integration with anammox processes.

  • Patent number: 10421679
    Abstract: Aerobic processes are disclosed for the treatment of wastewater which contains at least one substrate comprising at least one of organocarbon component and ammonium cation. A bioreactor is used for the treatment which contains ME biocatalysts to provide high bioreactor bioactivity density. The processes reduce sludge generated and are capable of effecting the metabolic oxidation at low dissolved oxygen concentrations.

  • Patent number: 10344302
    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.

  • Patent number: 9752164
    Abstract: Overlay processes are disclosed for making ethanol that not only increase ethanol conversion but do so in a cost effective manner with a reduction in energy requirements per unit of ethanol production. The processes can provide, if desired, higher organic compound as a co-product with ethanol.

  • Patent number: 9255281
    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.
