Patent number: 11535717Abstract: There is provided a novel ionic composite material that can be molded into various shapes using lignin sulfonic acid as one of raw materials thereof, and having flexibility and elasticity, to significantly improve the strength and toughness and impart complete biodegradability thereto. It was found that a combination of ?-polylysine (?-PL) which is a cationic polymer that is produced by microorganisms and lignin sulfonic acid exhibits excellent strength and toughness. In addition, ?-PL used in this technology is a biodegradable polymer that is completely degraded by microorganisms and the like in the environment. Since lignin sulfonic acid is also a biodegradable polymer, it is thought that a complex in which ?-PL and lignin sulfonic acid are mixed in this technology will exhibit complete biodegradability, and more applications thereof can be expected when utilizing the strength, durability, and biodegradability thereof in addition to the improved strength and toughness.Type: GrantFiled: January 30, 2020Date of Patent: December 27, 2022Assignees: JNC CORPORATION, NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGYInventors: Kazunori Ushimaru, Tokuma Fukuoka, Tomotake Morita

Publication number: 20120070396Abstract: The present invention includes as an active ingredient at least one biosurfactant, in particular mannosyl alditol lipid (such as MEL and MML) or triacylated mannosyl alditol lipid. This allows providing an activator and anti-aging agent that is excellent in activating and anti-aging effects on cells and that is safe enough to be used for a long time, and also providing cosmetics, quasi-drugs, drugs, and drinks and foods including the activator and the anti-aging agent as active ingredients. Further, the present invention provides MEL whose mannosyl erythritol skeleton in a molecular structure is 1-O-?-D-mannopyranosyl-meso-erythritol and a method for producing the MEL with use of a microorganism.Type: ApplicationFiled: October 19, 2011Publication date: March 22, 2012Applicants: National Institute of Advanced Industrial Science and Technology, TOYO BOSEKI KABUSHIKI KAISHAInventors: Michiko Suzuki, Masaru Kitagawa, Shuhei Yamamoto, Atsushi Sogabe, Dai Kitamoto, Tomotake Morita, Tokuma Fukuoka, Tomohiro Imura
