A fermentation tank is shown with an inlet for injecting at least one gaseous substrate into the tank, wherein the at least one gaseous substrate includes carbon dioxide (CO.sub.2). One or more sensors may be included. Such sensors may be selected for determining gasses (such as CO.sub.2, methane, oxygen, etc.), nutrition, minerals, and/or pH. Active or static mixing devices may be included. The tank may be used in a method for improving biomass production and/or growth rate of a microorganism in a fermentation process such as shown and disclosed.

A one-time use or repeated use self-contained biofilm-biomat reactor comprising a container with at least one compartment and placed within the compartment(s), a feedstock, a fungal inoculum, a gas-permeable membrane, and optionally a liquid nutrient medium is provided.

Provided herein are methods of producing a bioproduct by culturing a cell in a multiphase reactor that comprises supercritical CO.sub.2, near critical CO.sub.2, or liquid CO.sub.2.

Methods of production of edible filamentous fungal biomat formulations are provided as standalone protein sources and/or protein ingredients in foodstuffs as well as a one-time use or repeated use self-contained biofilm-biomat reactor comprising a container with at least one compartment and placed within the compartment(s), a feedstock, a fungal inoculum, a gas-permeable membrane, and optionally a liquid nutrient medium.

An inverted conical bioreactor is provided for growing cells or microorganisms. The bioreactor has an internal space and a perforated barrier within the vessel, through which a liquid may flow, where cells or microorganisms cannot pass through the perforated barrier. The perforated barrier divides the internal space of the bioreactor into a first chamber and a second chamber. Cells are grown within the second chamber and can be perfused by re-circulating the liquid, for example a growth medium, through the bioreactor. Various inlet ports and outlet ports allow controlling the parameters of flow of the growth medium.

The claimed invention is directed towards a novel combination cell electroporation/cell culturing apparatus which can be termed a cell culture dish suitable for in vitro electroporation, and towards a device suitable for in vivo electroporationboth useful in methods suitable for the generation of developmentally-activated, pluripotent, pluripotent-like, multipotent, and/or self-renewing cells which are capable of beginning to differentiate in culture into a variety of cell types and capable of further differentiation in vivo. The claimed invention is also directed towards the generation of desirable, differentiating somatic cell populations transplantable to animals or patients, genetic modification of endogenous and exogenous cells, and the treatment of patients suffering from diseases that may be ameliorated by these methods. This invention also provides methods for preventing, treating, or retarding disease, for example, immunodeficiency virus (e.g. HIV-1, HIV-2, SIV, FIV, etc.) infection.

A method for improving biomass production and/or growth rate of a microorganism in a fermentation process is shown, and includes: (i) providing one or more microorganisms; (ii) providing a fermentation substrate suitable for fermenting the one or more microorganisms; (iii) mixing the one or more microorganisms and the fermentation substrate providing a fermentation broth; (iv) adding the fermentation broth to a fermentation tank; (v) injecting at least one gaseous substrate into the fermentation broth; (vi) running the fermentation process for a fermentation period of at least 1 hour; wherein the at least one gaseous substrate comprises one or more greenhouse gases, such as carbon dioxide (CO.sub.2).

Methods of production of edible filamentous fungal biomat formulations are provided as standalone protein sources and/or protein ingredients in foodstuffs as well as a one-time use or repeated use self-contained biofilm-biomat reactor comprising a container with at least one compartment and placed within the compartment(s), a feedstock, a fungal inoculum, a gas-permeable membrane, and optionally a liquid nutrient medium.

A method of recovering a population of extracellular vesicles from a biological sample comprising extracellular vesicles and contaminants is described. In one embodiment, the method comprises: a) removing contaminants from the sample, wherein said contaminants are relatively larger or more dense than the extracellular vesicles; b) contacting the sample of step a) with a plurality of binding compositions, each binding composition having first and/or second moieties capable of binding a recognition motif of the target entities under conditions to allow complexing of the extracellular vesicles with the plurality of binding compositions to form a complexed population of extracellular vesicles, the complexed population of extracellular vesicles having an increased volume and/or higher density in comparison to the extracellular vesicles in individual form; and c) recovering the complexed population of extracellular vesicles.

A culture container includes a tube having a first and a second opening respectively provided at two opposite ends thereof, and a cover attachable to and removable from the first opening of the tube, the cover including an inlet port for passage of a fluid substance and a receptacle for holding a substance consumable by an organism of interest, the receptacle being enclosed inside the tube and the inlet port communicating with a hollow interior of the tube when the cover is attached to the first opening of the tube. Moreover, a system and a method of transferring a cultured organism of interest include switching the covers between two culture containers.
