  • Patent number: 12018242
    Abstract: The present invention relates to bioreactors for root organ cultures that enable large parts of the inoculation or biomass transfer, cultivation and harvest of the cultures to be performed outside of an aseptic environment. The present invention further relates to methods of producing and aseptically harvesting roots, and methods of producing root cultures using the aforementioned bioreactors alone or as part of an apparatus further comprising an inoculation vessel or at least one further bioreactor.
    Type: Grant
    Filed: December 21, 2018
    Date of Patent: June 25, 2024
    Assignee: Evologic Technologies GmbH

  • Patent number: 11530149
    Abstract: The present invention relates to an aqueous composition comprising cells of at least one strain of a halophilic microorganism, and alkali sulfate in a concentration of at least 30 g/l based on the total volume of the aqueous composition. The present invention further relates to a method for treating a waste water, comprising obtaining or providing a waste water, contacting said waste water with cells of at least one strain of a halophilic microorganism, and thereby generating an aqueous composition comprising alkali sulfate in a concentration of at least 30 g/l, and incubating said aqueous composition under conditions which allow for the treatment of the waste water.

  • Publication number: 20220298043
    Abstract: The present invention relates to a method for reducing the content of at least one pollutant selected from the group consisting of nitrobenzene, formate, phenol, 4,4?-Methylenedianilinc (MDA) and aniline of hypersaline wastewater, said method comprising the steps of (a) providing a composition A comprising hypersaline wastewater and said at least one pollutant, and (b) contacting composition A with Haloferax mediterranei cells, thereby generating a composition B comprising said composition A and cells of said at least one halophilic microbial strain. The present invention further concerns a method for the production of chlorine and sodium hydroxide. Further encompassed by the present invention is a composition comprising hypersaline wastewater, said at least one pollutant, and Haloferax mediterranei cells.

  • Patent number: 11377677
    Abstract: A method for producing a recombinant protein of interest (POI) is provided, comprising the steps of (a) culturing cells in a cell culture medium to express said POI by adding a feed comprising at least one substrate to said cell culture, (b) applying a feeding strategy based on calculating, setting and optionally controlling the specific substrate uptake rate qs of the cells during the induction phase and/or production phase of the POI, wherein qs is set to be close to the maintenance rate of the cell culture; and (c) isolating said POI from the cell culture.

  • Publication number: 20220135459
    Abstract: The present invention relates to a method for reducing the amount of organic compounds in wastewater, comprising providing a wastewater comprising NaCl in a concentration of at least 6% (w/v), contacting said hypersaline wastewater with a halophilic microorganism, and reducing the 5 amount of organic compounds by said halophilic microorganism in the presence of at least one substrate which has been added to the wastewater and which allows for the growth of said halophilic microorganism, wherein the reduction of the amount of organic components is carried out as a continuous process in bioreactor.

  • Patent number: 11247925
    Abstract: The present invention relates to a method for reducing the aniline content of hypersaline wastewater, said method comprising the steps of (a) providing a composition A comprising hypersaline wastewater and aniline, and (b) contacting composition A with cells of at least one halophilic microbial strain, thereby generating a composition B comprising said composition A and cells of said at least one halophilic microbial strain. The present invention further concerns a method for the production of chlorine and sodium hydroxide. Further encompassed by the present invention is a composition comprising hypersaline wastewater, aniline, and cells of at least one halophilic microbial strain.
