The present invention discloses the active substances for preventing hearing deterioration, its preparation method, the pharmaceutical composition containing the active substances, and the preparation method of the pharmaceutical composition. The preparation method of the active substances is performed by plate cultivation, flask cultivation and fermentation tank cultivation, to obtain the active substances of Hericium erinaceus mycelia in powder form. The powder of H. erinaceus mycelia is proved to have the effect of preventing hearing deterioration.

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).

A device for culturing anaerobic microorganisms is provided. The device comprises a body comprising a waterproof base, a waterproof coversheet attached to the base, and a growth compartment disposed between the base and the coversheet. The growth compartment has a perimeter and an opening that provides liquid access to the growth compartment. A portion of the perimeter is defined by a waterproof seal. The portion includes >50% of the perimeter. A dry cold water-soluble gelling agent is adhered to the base in the growth compartment. A dry first oxygen-scavenging reagent is disposed in the growth compartment.

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.

A process for culturing Clostridium saccharoperbutylacetonicum cells, which are capable of growing on gamma-cyclodextrin in a liquid culture medium in a culture vessel. Also disclosed is a process for producing a bio-product, the process comprising culturing Clostridium saccharoperbutylacetonicum cells, which are capable of growing on gamma-cyclodextrin in a liquid culture medium in a culture vessel.

Aspects of the present invention relate to a networked cell culture incubator and to methods for operating such an incubator. In one aspect, the cell culture incubator includes a network interface for communicating with a source of parameter data utilized successfully by other incubators. The incubator receives appropriate parameter data and conducts the incubation process as prescribed by the parameter data so as to provide an improved environment for cell culture growth. The incubator may share its own parameter data with the data source for use by other incubators. The incubator and data source may share other forms of data as well.

In one aspect, the cell culture incubator includes a network interface for communicating with a source of parameter data utilized successfully by other incubators. The incubator receives appropriate parameter data and conducts the incubation process as rescribed by the parameter data so as to provide an improved environment for cell culture growth. The incubator may share its own parameter data with the data source for use by other incubators. The incubator and data source may share other forms of data as well.

Embodiments described herein generally provide for the expansion of cells in a cell expansion system using an active promotion of a coating agent(s) to a cell growth surface. A coating agent may be applied to a surface, such as the cell growth surface of a hollow fiber, by controlling the movement of a fluid in which a coating agent is suspended. Using ultrafiltration, the fluid may be pushed through the pores of a hollow fiber from a first side, e.g., an intracapillary (IC) side, of the hollow fiber to a second side, e.g., an extracapillary (EC) side, while the coating agent is actively promoted to the surface of the hollow fiber. In so doing, the coating agent may be hydrostatically deposited onto a wall, e.g., inner wall, of the hollow fiber.
