Described are embodiments for expanding cells in a bioreactor. In one embodiment, methods are provided that distribute cells throughout the bioreactor and attach cells to specific portions of a bioreactor to improve the expansion of the cells in the bioreactor. Embodiments may be implemented on a cell expansion system configured to load, distribute, attach and expand cells.

Expanding cells in a bioreactor

Embodiments described herein generally provide for expanding cells in a cell expansion system. The cells may be grown in a bioreactor, and the cells may be activated by an activator (e.g., a soluble activator complex). Nutrient and gas exchange capabilities of a closed, automated cell expansion system may allow cells to be seeded at reduced cell seeding densities, for example. Parameters of the cell growth environment may be manipulated to load the cells into a particular position in the bioreactor for the efficient exchange of nutrients and gases. System parameters may be adjusted to shear any cell colonies that may form during the expansion phase. Metabolic concentrations may be controlled to improve cell growth and viability. Cell residence in the bioreactor may be controlled. In embodiments, the cells may include T cells. In further embodiments, the cells may include T cell subpopulations, including regulatory T cells (Tregs), for example.

20230016412 · 2023-01-19 ·

A system and method for making a liquid chemistry treated biopolymer-based fungal mat is described. The method comprises the steps of harvesting a plurality of fresh mycelium material and marking them for identification, then weighing and recording the initial mass of each of the plurality of mycelium material is carried out. A liquid chemical solution using solvent: chemical ratios from 0:100 to 100:0 is prepared. Next, decanting the liquid chemical solution into a vacuum tumbler drum distributed with the mycelium material. Applying vacuum and rotating the vacuum tumbler drum to ensure thorough mixing and refreshing of the liquid chemical solution at the mycelium surface. Vacuuming and rotating the vacuum tumbler drum is repeated and the at least one fungal mat formed is removed from the vacuum tumbler drum. Finally, draining away surface moisture and air drying the at least one fungal mat.

Micro algae harvesting methods and devices

The present invention relates to a particulate material separation assembly. It comprises a filtration membrane and an antifouling device. The antifouling device comprises one or more magnets and a plurality of magnetisable particles. The one or more magnets cause the plurality of magnetisable particles to self-assemble into dynamic bristles, thereby forming a brush. The particulate material separation assembly is particularly useful in the context of micro algae harvesting.
