Publication number: 20140099677Abstract: This present disclosure relates to methods for improved production of proteins from a cell culture, particularly to culture components and conditions that can preferentially increase the expression of proteins produced from genes under the control of xylanase gene promoter sequences. The improved methods can be used for the production of enzyme compositions with enhanced xylanase and hem icellulolytic activity.Type: ApplicationFiled: August 15, 2013Publication date: April 10, 2014Applicant: Danisco US Inc.Inventors: Aaron KELLEY, Chuanbin LIU, Colin MITCHINSON

Patent number: 8691536Abstract: To provide a pectin lyase and a gene for a pectin lyase which can be used in an enzyme preparation for processing plant tissue, and which possesses sufficient maceration activity even under highly acidic conditions. Isolation and purification of a pectin lyase and a gene for a pectin lyase having a molecular weight of 39,500 produced by an Aspergillus filamentous fungus, and possessing a maceration activity and a pectin lyase activity. The pectin lyase has a specified amino acid sequence, an optimal pH of 3.5 for maceration activity, an optimal pH of 4.5 for pectin lyase activity, and deactivates with boiling treatment for 15 minutes at 121° C. Sterilizing heat treatment are unnecessary, because the present invention possesses sufficient maceration activity at pH 3.0-4.0, and the resulting pectin lysate possesses a bactericidal activity and a potent antibacterial activity.Type: GrantFiled: July 15, 2010Date of Patent: April 8, 2014Assignees: Bio-I Co., Ltd.Inventors: Yoshihisa Nakano, Mitsuhiro Uenoyama, Erina Kobayashi
