A method for expanding circulating tumor cell in vitro includes preparing a cell culture tool having a multi-particle colloidal crystal layer, preparing a cell solution including circulating tumor cells, and contacting the cell solution with the multi-particle colloidal crystal layer, to attach the circulating tumor cells in the cell solution to the multi-particle colloidal crystal layer and rapidly expand by 20 times or more. The multi-particle colloidal crystal layer at least includes first particles having a particle size of 1000 to 5000 nm and second particles having a particle size of 20 to 400 nm. The culture medium in the cell solution at least includes a platelet lysate.

The invention relates to a method of increasing the yield of virus, virus particles, or viral vectors from host cells in a bioreactor. The invention provides a reproducible and robust method and system of determining and controlling the optimal time of infection of host cells using a correlation of process air parameters including Air flow, O.sub.2 flow, and respective trends thereof resulting in increased virus yield.

An active solid state fermentation bioreactor for producing gases, liquid(s) or solids from gaseous or gaseous and liquid starting materials and a fermentation process using the reactor are disclosed. The bioreactor includes three major phases; a solid phase including the porous solid support, a liquid phase comprising liquid, and a gaseous phase. The solid phase includes a porous solid support, in which at least 20% of the pore volumes have a size resulting in a liquid suction of about 0.01 to about 0.1 bars if these pores are filled with liquid, the porous solid support is inoculated with desired micro-organisms, the volume of the gaseous phase is 20% to 60% of the volume of the bioreactor, and the liquid phase is at least 20% of the reactor volume. The unsaturated capillary conductivity of filling/packing solid material of the bioreactor is at least 0.1 cm/h. The solid state fermentation bioreactor enables a large gas-liquid interface, in which the filling material has a good capillary conductivity despite the unsaturated state.

We have modified a commercially-available adherent cell culture bioreactor, developing a new sampling manifold configuration and new way of taking samples to reduce contamination risk.

Disclosed herein is an improved rocked bioreactor system used for carrying out cell and tissue cultures.

The present disclosure relates to a novel process to control odors from manure by digesting the manure into Methane. Embodiments may comprise a two stage anaerobic digestion process to digest the wastes and remove the nutrients from the wastewater. The initial anaerobic digestion is carried out in a closed vessel to capture any gassed released and otherwise proceeds as current practices are. The wastewater from the first stage digestion is then pumped into a second reaction vessel. This vessel reproduces the conditions that produce natural gas (methane) in the geologic setting, with high temperatures and high pressures.

A system and method for the production of microbial consortiums and by-product material is provided. A physical containment system comprising phase spaces arranged in a discrete order to favor specific biological reactions is also provided. Phase profiles and phase data sets include the pre-determined physical and biological parameters for the phase space transitions. Movement of material from one phase to the next is hydraulically balanced enabling working fluid to continuously move in a fixed direction and rate of flow. Continuous monitoring of phase profiles and phase data sets provide feedback to the system enabling alteration of the conditions in the system to control reactions therein

A sampler for use with a bioreactor for growing a cell culture is disclosed. In one embodiment, the bioreactor includes a structured fixed bed including a removable sample portion for recovering a sample of cells from the cell culture. Related apparatuses and methods are also disclosed.

This invention discloses a three-dimensional (3D) bioreactor for large scale expansion of immune cells and methods of use. The 3D bioreactor comprising at least one packed bed chamber comprising at least one porous scaffold; at least one porous scaffold coated with one or more extra cellular matrix protein (ECM); at least one container comprising a fluid media, the fluid media is configured to flow through said packed bed chamber with at least one porous coated scaffold; and at least one population of immune cells suspended in the fluid media, wherein, the at least one porous scaffold coated with said ECM is creates a stationary niche having low shear forces that imitate the natural growth environment of the immune cells and allows expansion of the immune cells population that flow through the coated porous scaffold in large scale.
