Publication number: 20240258622Abstract: A deep-sea battery device includes: a housing, a pouch, and a protective cover. The housing defines a pressure-releasing port, the pouch seals the pressure-releasing port. The pouch includes a body, a cushioning portion, and a connection portion. The cushioning portion is disposed between the body and the connection portion. The connection portion is clamped between the protective cover and the housing. The cushioning portion at least comprises an annular cushioning protrusion surrounding a periphery of the body. The cushioning protrusion protrudes toward an interior of the housing. A side of the cushioning protrusion away from the interior of the housing defines a groove. An opening of the groove faces the protective cover. The protective cover defines a through hole, the through hole is disposed at a position corresponding to the body. The body is disposed lower than an outer side of the housing that defines the pressure-releasing port.Type: ApplicationFiled: April 15, 2024Publication date: August 1, 2024Inventors: JIEYU ZHOU, XIAOKANG LI, DONGRONG QI, PENGCHENG LIU, ZHIMIAO LI

Patent number: 11542479Abstract: The invention discloses an alcohol dehydrogenase mutant and use thereof. The alcohol dehydrogenase mutant of the present invention has high thermal stability and enables high catalytic efficiency and high conversion rate (i.e. space time yield) in the asymmetric reduction of prochiral diaryl ketones to produce chiral diaryl alcohols. Therefore, the alcohol dehydrogenase mutant of the present invention has extremely high prospect of application in the production of chiral diaryl alcohols, such as (S)-(4-chlorophenyl)-(pyridin-2-yl)-methanol, (R)-(4-chlorophenyl)-(pyridin-2-yl)-methanol.Type: GrantFiled: May 13, 2020Date of Patent: January 3, 2023Assignee: JIANGNAN UNIVERSITYInventors: Ye Ni, Wei Dai, Guochao Xu, Jieyu Zhou, Ruizhi Han, Jinjun Dong

Patent number: 11162124Abstract: Disclosed is an alcohol dehydrogenase mutant and application thereof in cofactor regeneration, and belongs to the technical fields of enzyme engineering and bioengineering. The alcohol dehydrogenase mutant is obtained by mutating valine at position 84 and/or tyrosine at position 127 in alcohol dehydrogenase having an original amino acid sequence as set forth in SEQ ID No. 1. The alcohol dehydrogenase mutant has high activity for a variety of alcohol co-substrates, and can catalyze these enzyme co-substrates for the regeneration of cofactor NADPH. Compared with the wild-type alcohol dehydrogenase KpADH, the alcohol dehydrogenase mutant has higher activity and catalytic efficiency, and for co-substrate 1,4-butanediol, its kcat value can be up to 75.9 min?1, its kcat/Km value can be up to 2009 min?1·M?1, and its Km value can be as low as 11.3 mM. Therefore, the alcohol dehydrogenase mutant has a higher value in industrial application.Type: GrantFiled: April 14, 2020Date of Patent: November 2, 2021Assignee: JIANGNAN UNIVERSITYInventors: Ye Ni, Cheng Zhu, Guochao Xu, Jieyu Zhou
