  • Patent number: 10662487
    Abstract: A Pseudomonas sp. ECO-1 strain was preserved at the China General Microbiological Culture Collection Center (CGMCC) on Mar. 31, 2017, with the preservation number of CGMCC No. 13960. The Pseudomonas sp. ECO-1 strain was separated from POPs (Persistent Organic Pollutants) polluted soil for the first time. The bifunctional enzyme preparation capable of efficiently degrading polychlorinated biphenyl and atrazine was prepared by utilizing the strain for the first time; especially, the bifunctional enzyme preparation has remarkable degradation activity on the polychlorinated biphenyl which is difficult to degrade under an aerobic condition, which is completely different from functions of existing known Pseudomonas sp. and enzyme preparations thereof.

  • Patent number: 10227274
    Abstract: Disclosed are systems and methods which provide a process stream comprising a gaseous component, capture the gaseous component from the process stream by an ionic liquid solvent of a separator, and recover a captured gaseous component from the ionic liquid solvent in a regenerator. A second gaseous component from the process stream may be captured by the ionic liquid solvent of the separator, and the second gaseous component may be recovered from the ionic liquid solvent in the regenerator. Alternatively, the second gaseous component from the process stream may be uncaptured by the ionic liquid solvent, and the uncaptured second gaseous component may be recovered from a membrane unit.
