A cell separation device configured for separating cells from microcarriers or spheroids in a liquid is provided. The cell separation device includes a vessel comprising a first port, a second port, and a cavity; and a porous mesh disposed within the cavity to divide the cavity into a first compartment and a second compartment, wherein the first port is in communication with the first compartment of the cavity, the first port located to a first side of the porous mesh, wherein the second port is in communication with the second compartment of the cavity, the second port located to a second side of the porous mesh, and wherein the porous mesh is positioned within the cavity to have a substantially vertical orientation or an inclined orientation with respect to a flow of liquid through the porous mesh.

Growth methods and systems herein include a growth container with one or more meshes attached thereto. The growth container and its meshes can hold a substrate. The growth container and its meshes can be vertically oriented to allow fungal biomass (e.g., mycelium, fruiting body, primordia, etc.) to grow from the substrate and through the meshes. The growth containers can be cylindrical or a rectangular box having meshes extending along vertically oriented longitudinal sides. The meshes may be provided on two opposite sides of the growth cylinders. These meshes can expose the substrate to a growth environment to facilitate growth of the fungal biomass.

Separating apparatus, comprising a sedimentation settler and a collection vessel disposed underneath and being in fluid communication with the sedimentation settler, the collection vessel forming a receiving chamber having an outlet at or adjacent to the chamber bottom and having an inlet opening, wherein the collection vessel is arranged such the flow direction of the fluid in the area underneath the sedimentation settler is substantially in line with the direction of the channels of the sedimentation settler.

The present disclosure provides cassettes for use in automated cell engineering systems that include cell concentration filters for reducing fluid volume of a cell sample during or following automated processing. The disclosure also provides methods of concentrating a cell population, as well as automated cell engineering systems that can utilize the cassettes and carry out the methods.

Harvesting methods and systems for harvesting fungal biomass from a growth container using one or more meshes is described. The growth container includes a first mesh through which the fungal biomass grows. A second mesh can be disposed over the first mesh such that the fungal biomass grows further through the second mesh. A rotator or a slider can be coupled to the second mesh and configured to move the second mesh relative to the first mesh causing the fungal biomass to shear and transport the fungal biomass on the second mesh to a delivery area.

Systems and methods for producing carbohydrate (e.g., sugar) streams (and recycling enzymes) from a pretreated or untreated biomass such as cellulosic feedstock, including, for example, “brown stock” feedstock, or waste or recycled fiber sludge produced in the pulp and paper industry, such as for biochemical (e.g., biofuel) production, are provided. In one example, the system and method can produce high purity C6 (glucose and/or fructose) and/or C5 (xylose) sugar streams, and other carbohydrates and/or fibrous materials, from cellulosic feedstocks, such as brown stock or waste fiber sludge, that can be effectively converted into various biochemical products, such as ethanol.

Growth and harvesting methods and systems herein include a growth container with one or more meshes attached thereto. The growth container and its meshes can hold a substrate. The growth container and its meshes can be vertically oriented to allow fungal biomass (e.g., mycelium, fruiting body, primordia, etc.) to grow from the substrate and through the meshes. The growth containers can be cylindrical or a rectangular box having meshes extending along vertically oriented longitudinal sides. The meshes may be provided on two opposite sides of the growth cylinders. These meshes can expose the substrate to a growth environment to facilitate growth of the fungal biomass. A cutter is configured to move relative to the growth container to harvest the fungal biomass across the mesh while preventing the substrate from sticking to the harvested fungal biomass.

Disclosed herein is a cell harvesting instrument suitable for concentrating cells from a source suspension of cells and/or washing said cells, the instrument comprising: a housing for accommodating mechanical elements including at least one fluid pump, at least one valve; and a processing kit removably insertable into the housing, said kit including a generally flat frame having or supporting plural sealed fluid paths arranged in a generally flat plane and such that fluids in the paths do not contact said mechanical elements, wherein at least portions of the fluid paths comprise flexible tubes, the outer surfaces of which are manipulateable by the or each fluid pump, to provide fluid flow in one or more of the paths and/or by the or each valve to restrict fluid flow in one or more of the paths. In an embodiment, the kit comprises also a fluid processing reservoir and a filter suitable for separating cells from fluid in said paths. A transfer mechanism for moving and weighing the fluid processing reservoir is disclosed also.

Disclosed herein are cell processing systems, devices, and methods thereof. A system for cell processing may comprise a plurality of instruments each independently configured to perform one or more cell processing operations upon a cartridge, and a robot capable of moving the cartridge between each of the plurality of instruments.

Embodiments of the present invention provide an automatic micro algae culturing device and system for self-cleaning, continual automatic algae culturing and irradiant optimizing. The culturing device includes a photosynthesis tubular reactor for micro algae culturing, with transparent cleaning particles to scrape off any unwanted particles or components such as including and not limited to formation of biofilm. The device also includes a nano-air bubble generating device installed around the tubular reactor to generate and feed nano-air bubbles into the tubular reactor, where the nano-air bubbles increase an active surface area for ions to interact with the algae in the culture medium in order to increase productivity of the culturing device by enhancing rate of mitosis, productively of oil, protein and polysaccharide and the nano-air bubbles also sterilizes the culture medium.
