Abstract: Methods of inhibiting or reducing tumor metabolism and growth are disclosed. A composition containing oxygen scavenging membrane fragments and anaerobe bacteria is injected into a tumor to interfere with tumor growth and metabolism, leading to tumor necrosis. The composition may also contain a cryoprotectant, which permits the composition to be stored at sub-zero temperatures without freezing.

Abstract: A culture system includes a dish and a lid. The dish comprises a base, a sidewall extending from the base, and a track extending outwardly from an outer surface of the sidewall. The lid comprises a central horizontal wall and a recess formed by two sidewalls and a top wall. At least one key extends downwardly from the recess. The sidewall of the dish extends into the recess of the lid, and the key engages the track. The track is shaped so that the lid rises or falls relative to the base of the dish when the lid is rotated relative to the dish.

Abstract: Methods of inhibiting or reducing tumor metabolism and growth are disclosed. A composition containing oxygen scavenging membrane fragments is administered within a tumor to create a hypoxic environment. This interferes with tumor growth and metabolism, and can lead to tumor death.

Abstract: Methods of preserving and storing biological specimens, particularly anaerobe microorganisms are disclosed. A composition containing oxygen scavenging membrane fragments and a cryoprotectant is administered to the specimens. The specimens are then stored at a temperature that is lower than 0° C. and greater than ?70° C. Cryogenic freezing is not required.

Abstract: The present invention is directed to a medium, broth or agar, and a method of utilizing the same, in order to isolate and/or identify anaerobes from a mixed sample that contains facultative microorganisms. The medium contains an inhibitor of the electron transport system, such as a salt of azide (N3?), cyanide (CN?) or related compounds. These inhibitors are present in an amount sufficient to limit the growth of facultative microorganisms under anaerobic conditions while not inhibiting the growth of the anaerobe microorganisms. Preferably, the inhibitor is present in the amount of from about 0.1 mg/ml to about 1.0 mg/ml in broth medium, and from about 0.01 mg/ml to 1.0 mg/ml in agar medium.

Abstract: The present invention is directed to a novel method, composition and device for removing dissolved oxygen from solutions containing alcohols and/or acids. By removing oxygen from various products, the present invention is an effective antioxidant for beverages and food products, as well as for industrial and commercial solutions containing alcohols and/or acids.

Abstract: An apparatus for growing anaerobic microorganisms is provided having a dish top that contains a sealing ring upon which the media surface in the dish bottom rests when the apparatus is inverted. The contact between the sealing ring and the media surface forms a seal that traps the gas in the headspace between the media surface and the inside of the dish top. A oxygen reducing agent can also be incorporated into the media together, in some instances, with a substrate which react with oxygen in the media and with oxygen in the headspace thereby creating an environment suitable for growing anaerobic, microaerophilic and facultative anaerobic microorganisms.

Abstract: The present invention is directed to an apparatus for removing oxygen from a fluid stream. The apparatus is comprised of a flow through reactor chamber containing a sufficient amount of oxygen scavenging cell membrane fragments to catalyze the transformation of oxygen present in a fluid stream to water. The fragments are contained in the apparatus in a manner which allows free contact between the fragments and the fluid stream flowing therethrough or for the diffusion of the oxygen from the fluid stream across a synthetic membrane to a compartment containing the fragments where the oxygen is transformed to water. An inlet for introducing a fluid stream containing oxygen into said flow-through reaction chamber and an outlet for removing the deoxygenated fluid stream are also provided.

Abstract: The present invention is directed to a novel method and device for removing oxygen from oils. The oils may be in liquid form, such as vegetables oils, etc., in solid form, such as fats, etc. or in some type of intermediate semi-solid form. By removing oxygen from various products containing oils and fats, the present invention is an effective antioxidant for food products, as well as for various industrial and commercial products, such as paints, varnishes, etc. The method comprises the steps of providing an oil containing oxygen and adding to the oil a sufficient amount of an aqueous solution containing oxygen scavenging membrane fragments and a hydrogen donor substance to reduce the oxygen present in the oil to water.
