Patent number: 11976267Abstract: The invention provides a recombinant Escherichia coli strain for producing succinic acid and a construction method thereof. The by-product encoding genes in the E. coli strain FMME-N-2 are knocked out to obtain the E. coli strain FMME-N-5 (?focA-pflB-?ldhA-?pta-ackA); and the phosphoenolpyruvate carboxykinase pck derived from Actinobacillus succinogenes and the phosphite dehydrogenase ptxD derived from Pseudomonas stutzeri were overexpressed. The constructed plasmid pTrcHisA-pck-ptxD was introduced into the expression host E. coli FMME-N-5 (?focA-pflB-?ldhA-?pta-ackA), and the cells were screened in a plate containing ampicillin, to obtain an engineered strain E. coli FMME-N-5 (?focA-pflB-?ldhA-?pta-ackA)-pck-ptxD that can efficiently produce succinic acid. After fermentation by a two-stage fermentation strategy, the production of succinic acid reaches 137 g/L, the yield of succinic acid is up to 1 g/g glucose, and the space time yield is 1.Type: GrantFiled: November 12, 2020Date of Patent: May 7, 2024Assignee: JIANGNAN UNIVERSITYInventors: Liming Liu, Wenxiu Tang, Chen Shen, Qiuling Luo, Xiulai Chen, Jia Liu, Cong Gao, Wei Song

Patent number: 11954332Abstract: Embodiments of the present disclosure provide a data processing method, a controller, a storage device, and a storage system. The controller adds an execution time of an IO request to the IO request, and the execution time is used to instruct the storage device to complete the IO request before the execution time expires. The controller sends, to the storage device, the IO request to which the execution time is added. When receiving the IO request, the storage device can execute the IO request based on the execution time of the IO request.Type: GrantFiled: June 14, 2021Date of Patent: April 9, 2024Assignee: Huawei Technologies Co., Ltd.Inventors: Liming Wu, Guoxia Liu, Jizhuo Tang, Po Zhang
