Provided herein are a device and a method for preparation of immobilized proteins, enzymes or cells on a carrier to achieve the industrial batch production of the immobilized proteins, enzymes or cells.

According to present disclosure, there is disclosed an algae growth and cultivation system that provides a cost-efficient means of producing algae biomass as feedstock for algae-based products, such as, biofuel manufacture, and desirably impacts alternative/renewable energy production, nutrient recovery from waste streams, and valued byproducts production. The system as discussed herein is an integrated systems approach to wastewater treatment, algal strains selection for byproducts production, and recycle of algal-oil extraction waste or additional algae harvested as feedstock for fertilizer production. Embodiments of a system as discussed herein present an economically viable algae production system and process that allows algae-derived products such as biofuels, fertilizer, etc. to compete with petroleum products in the marketplace.

A cell culture device includes a container having a surface and a plurality of nano-bristles immobilized to the surface. The nano-bristles are made of styrene copolymer or oligopeptide. A method of partially detaching stem cells from a cell culture device includes: seeding stem cells onto the plurality of nano-bristles, culturing the stem cells, detaching a portion of the stem cells from the nano-bristles by a change in temperature or a shear force, and harvesting the portion of the stem cells.

Provided herein are a device and a method for preparation of immobilized proteins, enzymes or cells on a carrier to achieve the industrial batch production of the immobilized proteins, enzymes or cells.

A cell adhesion composition according to one aspect of the present invention comprises: an amphiphilic compound; and a conjugate of a DNA and a hydrophilic molecule, wherein the amphiphilic compound has a hydrophobic group that can non-covalently bond to a cell membrane, and a hydrophilic group, and wherein a weight-average molecular weight of the hydrophilic molecule of the conjugate is larger than a weight-average molecular weight of a hydrophilic molecule from which the hydrophilic group of the amphiphilic compound derives. According to such a cell adhesion composition, it is possible to impart a cell adhesion ability to a base material at an arbitrary timing by using light having an arbitrary wavelength.

A system and method for creating mycelium textile materials is disclosed, in which leftover, cutoff, and other materials used to create the textile materials that would otherwise be discarded are further used in a second process to create bonded mycelium boards. The system and method further reuse or recycle materials throughout the process of creating the mycelium textile fabric and bonded mycelium boards, thus keeping waste to a minimum.
