Publication number: 20220356517Abstract: The invention discloses a method for identifying the bacterial species and key functional genes thereof involved in antimony reduction in the soil. After consuming the original substrate by starvation culture, the sole metabolic substrate is added and the sole electron acceptor Sb(V) is provided, so that there is only one dominant electron exchange process in the system. The microorganisms metabolize and oxidize the organic substrate while coupling with the reduction of antimony, so that Sb(V) gets electrons and is reduced to Sb(III). The present invention observes the Sb(V) reduction in an anaerobic culture system of paddy soil under Sb(V) stress, and uses DNA-SIP technology to identify the phylogenic information of microorganisms that can drive the Sb(V) reduction in the culture system.Type: ApplicationFiled: January 9, 2020Publication date: November 10, 2022Inventors: Weimin Sun, Baoqin Li, Ling Lan, Xiaoxu Sun, Miaomiao Zhang, Qi Wang, Lang Qiu, Xiaoyu Wang

Patent number: 11044230Abstract: A port listening request dynamically generated by an application process hosted in a container can be identified. Whether the application process hosted in the container is trusted can be determined. Responsive to determining that the application process hosted in the container is trusted, a first port to be used as an external port for the application process can be dynamically selected, and a port assignment can be communicated to a container engine, the port assignment indicating the first port is assigned to the application process. The first port can be mapped to a second port assigned as an internal port for the application process. The first port can be opened for the application process.Type: GrantFiled: August 30, 2019Date of Patent: June 22, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ling Lan, Hongxia Li, Hai Long Liu, Xin Peng Liu
