    Abstract: The invention provides a method for the filtration of a bioreactor liquid (10) from a bioreactor (1) with a cross-flow membrane module (20) comprising one or more membranes (40). The method comprises feeding part of the bioreactor liquid (10) to a liquid inlet (21) of the cross-flow membrane module (20), transporting the bioreactor liquid (10) through the cross-flow membrane module (20) in a cross-flow mode, and removing a retentate (12) from a liquid outlet (22) of the cross-flow membrane module (20). The cross-flow membrane module (20) is arranged to allow a liquid downward flow of the bioreactor liquid (10) through the cross-flow membrane module (20). The method further comprises providing the liquid downward flow and a downward gas flow of a gas (30) through the cross-flow membrane module (20). Fouling of the membranes is relatively good prevented or reduced in time. Further, the liquid flow may be reduced relative to conventional configurations.

  • Patent number: 8043848
    Abstract: In a bioreactor, a culture solution derived from a cultivation tank is separated into bacteria cells and filtrate by a bacteria cell filter. The filtrate is introduced from the bacteria cell filter into a micro-nano bubble generation tank where micro-nano-bubbles are mixed with the filtrate. The filtrate containing micro-nano-bubbles is returned to the cultivation tank to activate the microorganisms therein, so that a biological reaction time is reduced by the activated microorganisms.

  • Publication number: 20110053228
    Abstract: A system and method are provided which utilize microbes to convert biomass feedstock into a fuel. In one aspect, a method of producing aromatic compounds and lipids includes: receiving a feedstock including biological matter; separating the feedstock into a liquid phase feedstock and a solid phase feedstock; adding water and nutrients to the solid phase feedstock, thereby producing a liquid culture; inoculating the liquid culture with microbes capable of converting the solid phase feedstock into aromatic compounds and lipids, the inoculated liquid culture yielding microbial biomass; providing suitable conditions for the microbes to convert the solid phase feedstock to aromatic compounds and lipids; and extracting produced aromatic compounds and lipids.

  • Patent number: 7897377
    Abstract: The present invention relates to the field of cell and tissue culture. In particular, the invention provides a novel device for organotypic culture. The device comprises a medium conduit having one open end and one end closed by a porous membrane fused across it; and a frame holding the medium conduit in a substantially vertical orientation; wherein the medium conduit is adapted to permit retention by capillarity of a sufficient volume of liquid culture medium in the medium conduit to contact the surface of the porous membrane and thus supply nutrients to cells that may be grown on the porous membrane. The device may further comprise a cell suspension conduit having one end open and one end closed by the surface of said porous membrane contralateral to the surface of said porous membrane sealed to said medium conduit; wherein said frame holds the medium conduit and the cell suspension conduit in a substantially vertical orientation.

  • Patent number: 7888111
    Abstract: An object of the present invention is to provide a cell culture vessel which is simple in structure and easy to handle, and is capable of preventing damage to the cells when separated, promoting transport of nutrients and excretion of effete matter, and elevating the culturing efficiency improving effect by the structural features. In order to attain the above object, there is provided a cell culture vessel including a culture section provided with a plurality of projections having an equivalent diameter smaller than the cells to be cultured and the culture section side walls enclosing the culture section, wherein the distance between an arbitrary position on the culture section/side wall boundary line and the nearest projection is smaller than the diameter of the cells to be cultured. The effect of the projections in the vessel given to the cultured cells is enhanced.
