Patent number: 10982246Abstract: The present invention discloses an industrial scale method to obtain 1-kestose by the use of a recombinant fructosyltransferase (FTF), isolated from Festuca arundinacea, expressed constitutively in a non-saccharolytic yeast. In this invention, the recombinant FTF type sucrose:sucrose 1-fructosyltransferase (1-SSTrec) is produced constitutively, stable and at high yield, both in the culture supernatant and in intact cells of the host Pichia pastoris. Hence, the invention additionally provides a method for 1-SST production at industrial scale. The recombinant enzyme is then used for mass production of short-chain fructooligosaccharides (FOS), specifically 1-kestose, from sucrose. The method of the present invention establishes conditions that allow conversion rates where the synthesized FOS constitute above 55% (w/w) of the total sugars in the reaction mixture and the 1-kestose content reaches values higher than 90% (w/w) of the total FOS fraction.Type: GrantFiled: October 22, 2018Date of Patent: April 20, 2021Assignee: Centro de Ingenierla Genética y BiotecnologiaInventors: Enrique Rosendo Pérez Cruz, Lázaro Hernández Garcia, Duniesky Martínez García, Luis Enrique Trujillo Toledo, Carmen Menéndez Rodríguez, Alina Sobrino Legón, Ricardo Ramírez Ibañez, Gumersindo Feijoo Costa, Juan Manuel Lema Rodicio

Patent number: 8651697Abstract: Disclosed is a lighting system and a method to change the internal light source of the lighting system, wherein maintenance and aesthetic considerations make it necessary to access the internal light source solely from the front of the lighting system without moving or removing a sign face. Access, in part, is provided by a light baffle track system inside the light system that turns a flexible light baffle (i.e., the light source) within the service box from a substantially vertical orientation to a substantially horizontal orientation as the flexible light baffle is removed and reinstalled through the service box and front access door. The flexible light baffle and light baffle track system work in concert to efficiently turn the flexible light baffle solely within the service box such that the height and depth of the service box is minimized.Type: GrantFiled: September 14, 2011Date of Patent: February 18, 2014Assignee: Icon Identity SolutionsInventors: Evan D.

Publication number: 20140006747Abstract: An extended translation look-aside buffers (eTLB) for converting virtual addresses into physical addresses is described, which includes both a set associative memory structure (SAM) and a content addressable memory (CAM) structure. An improved approach for operating an eTLB is described in which the same instruction is issued to perform the same task regardless of the exact underlying memory structure within the eTLB being accessed. For flush operations, the same instruction to perform a TLB flush can be provided to the eTLB that operates upon both the CAM and the SAM, which is then handled differently by the underlying implementation system of the eTLB depending upon whether the CAM and/or SAM is being accessed.Type: ApplicationFiled: June 29, 2012Publication date: January 2, 2014Applicant: Broadcom CorporationInventors: Wei-Hsiang CHEN, Ricardo RAMIREZ
