The microfluidic chip includes at least one microfluidic unit which includes two fluidic compartments, such as upper and lower, separated by a permeable supporting structure, one or more access opening for the fluidic compartments, and a set of lids interchangeable with a set of insets. The permeable support structure serves as a support for the organotypic culture. The upper and lower compartments may include inlets and outlets which allow fluids to be perfused into the lower compartment and fluids to be perfused into the upper compartment. The access opening may be closed with a lid or accommodate an inset.
Bioreactor with scaffolds
A bioreactor for culturing of cells is described. Screens suitable as a cell growth scaffold may comprise crossed fibers. Screens may be contained loosely in a screen holder, which in turn may be contained inside a manifold assembly. A lower manifold, screen holder and upper manifold may have identical or similar interior open cross-sections. Flow of liquid medium can occur upwardly through the array of screens, then flowing over a weir in the presence of an air pocket, and into a moat and a pump. The screen holder may have slots whose exterior-facing ligaments are rounded, and may have grooves whose interior-facing edges are rounded. These components may be located inside an incubator suitable to maintain desired environmental conditions and cleanliness.
PUMPLESS INTERNAL CIRCULATION PHOTOBIOREACTOR FOR HYDROGEN PRODUCTION
A new pumpless internal circulation photobioreactor for hydrogen production, including: an outer reaction barrel and an inner reaction barrel made of transparent materials, a gas collecting device, and an air duct arranged between the inner reaction barrel and the outer reaction barrel. An outer ring-shaped reaction chamber is formed between the inner reaction barrel and the outer reaction barrel. Liquid permeation holes and air holes are arranged on the inner reaction barrel. The gas collecting device is communicated with the outer ring-shaped reaction chamber. The air duct is communicated with the interior of the inner reaction barrel and the outer ring-shaped reaction chamber. The present invention has a simple and compact structure and is easy to operate, and gas produced by the reactor can be re-introduced into the reaction solution to provide aerodynamic power for stirring the reaction solution, which realizes low energy consumption and high-efficiency hydrogen production.
ONSITE MICROORGANISM-BASED TREATMENT METHOD, SYSTEM AND APPARATUS
Conventional methods for treating fat, oil, grease (FOG) and other build-up in wastewater systems (including grease traps) of restaurants and the like typically rely on chemical-based detergents, which may be damaging both to the environment and to the wastewater system itself. While some bio-friendly alternatives are known, a common problem with all these agents is that they are “flushed through” the system rapidly, and thus are relatively ineffective and inefficient. In providing an onsite system and method comprising cultivating micro-organisms and then using a carrier to deliver them to an affected environment, the present invention provides a solution that is more efficient in requiring less “starter” ingredients as well as more effective in ensuring the cultivated micro-organisms are delivered to, maintain sustained contact with, and have adequate time to treat, the undesirable substance(s).
