Patent number: 9296781Abstract: System and methods for isolation of collagen and other fibrous tissue from adipose tissue are described herein. The method of the present invention isolates the collagen from adipose tissue by sonication. The tissue to be sonicated is placed in a container or a flow cell transparent to ultrasound waves. After sonication the sonicated material is filtered out through the bottom of the flow cell and the sonicated collagen is trapped in the filter, which may be taken for further processing. The isolated collagen can then be combined with a suitable carrier for re-injection to correct various tissue defects such as wrinkles, to form a carrier for the stem cells, a filler, and matrix for new collagen production by injecting into the desired area of the host.Type: GrantFiled: June 22, 2012Date of Patent: March 29, 2016Assignee: VERIS MEDICAL, INC.Inventor: Stephen Schendel

Patent number: 9238802Abstract: A flavin-bound glucose dehydrogenase (FAD-GDH) with high substrate specificity for D-glucose. A gene encoding a mutant FAD-GDH with its N-terminal region, containing an amino acid sequence corresponding to MKITAAIITVATAFASFASA that exists in the N-terminal region, deleted from the amino acid sequence of a wild-type FAD-GDH derived from Mucor is introduced into E. coli to obtain an E. coli transformant. Subsequently, this E. coli transformant is cultured to obtain an FAD-GDH with a specific N-terminal region deleted. The transformant allows the production of a large amount of GDH in a short time as compared with the original microorganism. An FAD-GDH that is less susceptible to the effects of dissolved oxygen and allows accurate measurement of glucose even in the presence of sugar compounds other than glucose in a sample.Type: GrantFiled: November 30, 2011Date of Patent: January 19, 2016Assignee: KIKKOMAN CORPORATIONInventors: Ryoko Tajima, Atsushi Ichiyanagi, Eriko Yoshihara, Kozo Hirokawa

Patent number: 9234214Abstract: A fermentation process includes contacting a carbohydrate source with a microorganism in an aqueous fermentation broth to form a fermentation product which is a salt or a product with a boiling point above the boiling point of water. The fermentation process is carried out at a pressure which is below atmospheric pressure and at least at the value where the reaction medium is at its boiling point at the fermentation temperature. Water is evaporated and removed from the reactor during the fermentation in an amount which is at least 20% of the volume of liquid present in the reactor at the start of the fermentation. A fermentation process at reduced pressure while removing a substantial amount of water removes a surplus of water in the system, ensures removal of reaction heat, and may lead to improved fermentation quality.Type: GrantFiled: October 14, 2010Date of Patent: January 12, 2016Assignee: Purac Biochem BVInventors: Jan Van Breugel, Willem Jacob Groot, Peter Paul Jansen
