A separation system, a method in a separation system and an elution arrangement to be provided in a separation system for separating a biomolecule from a cell culture are provided. The method comprises the steps of: providing a feed from a cell culture (3; 103; 203) comprising said biomolecule to a magnetic separator (5; 105; 205) and providing to the magnetic separator magnetic beads comprising ligands capable of binding this biomolecule; separating by the magnetic separator said magnetic beads with bound biomolecules from the rest of the feed; forwarding said magnetic beads as a slurry with an added buffer to an elution cell (7; 107; 207); eluting the bound biomolecules in the elution cell.

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.

A cell treatment apparatus capable of treating cells in a cell culture vessel. The cell treatment apparatus (100) according to the present invention includes a first region (1), a second region (3), and a third region (5). The first region (1) and the second region (3) are placed in succession. The first region (1) is a cell treatment chamber for treating cells. The cell treatment chamber can be closed from the outside of the cell treatment chamber and includes a culture vessel placement portion for placing a cell culture vessel. The second region (3) includes a laser irradiation device capable of irradiating the cell culture vessel placed in the culture vessel placement portion with a laser. The third region (5) includes a control device that controls at least one device in the cell treatment apparatus (100) and a power supply device (52) that supplies electric power to at least one device in the cell treatment apparatus (100). The culture vessel placement portion is placed to be adjacent to the second region (3) in the cell treatment chamber. An adjacent portion to the second region (3) in the culture vessel placement portion is translucent.

Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce a product or intermediate, e.g., energy, a food, a fuel, or a material.

Devices and methods for influencing an organism included in a fluid by a light source immersed in the fluid, wherein a motion of the light source in the fluid is or can be pre-set and/or adjusted. Culturing and killing/debilitating are examples of influencing an organism. A light source immersed in a culture milieu provides fouling free supply of photonic energy to the culture milieu growing phototropic or mixotrophic organisms and operating in continuous or semi continuous or batch or semi-batch mode. The light source for delivering light energy in a facility for culturing an organism, a device for delivering light energy in a facility for culturing an organism, a facility 30 culturing an organism, and a method for operating a facility for culturing an organism are provided.

The invention discloses an immunoglobulin-binding magnetic bead, comprising a porous matrix and one or more magnetic particles embedded in said matrix, wherein said matrix comprises a porous polymer and at least 10 mg/ml Fc-binding proteinaceous ligands covalently coupled to said porous polymer.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) or other materials are processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the walls and optionally the ceiling include discrete units. Such vaults are re-configurable.

Microfluidic filter devices and methods of fabricating such devices. A microfluidic filter device for capturing an object (e.g., a red blood cell) can include a filter structure having a plurality of through holes extending from a first side of the filter structure to a second side of the filter structure and arranged in a repeating pattern, the through holes sized to capture the object. The device further includes a substrate including a plurality of vanes that supports at least a portion of the filter structure, a plurality of electrodes comprising a set of electrodes associated with each through hole, each set of electrodes including at least a pair of electrodes associated with each through hole and aligned with its associated through hole to apply electrical forces to an object captured in the through hole, and electrical connections to each of the plurality of electrodes.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, equipment, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which hazardous gases are removed, destroyed and/or converted. The treatments are efficient and can reduce the recalcitrance of the lignocellulosic material so that it is easier to produce an intermediate or product, e.g., sugars, alcohols, sugar alcohols and energy, from the lignocellulosic material.

The invention provides schemes for the integration of a fermentation process, with an electrolysis process, and a C1-generating industrial process. In particular, the invention provides process for utilizing electrolysis products, for example H.sub.2 and/or O.sub.2, to improve the process efficiency of at least one of the fermentation process or the C1-generating industrial process. More particularly, the invention provides a process whereby, H.sub.2 generated by electrolysis is used to improve the substrate efficiency for a fermentation process, and the O.sub.2 generated by the electrolysis process is used to improve the composition of the C1-containing tail gas generated by the C1-generating industrial process.
