The invention discloses a Kurthia gibsonii strain with low temperature tolerance and application of the Kurthia gibsonii strain in phosphorus removal of sewage and sludge, and belongs to the technical field of application of environmental microorganisms. According to the present invention, the Kutta gibsonii strain is obtained through separation, is named as the Kutta gibsonii LJY-006, and is preserved in the China Center for Type Culture Collection (CCTCC) with the preservation number of CCTCC No: M 2023907; the Kutta gigantei LJY-006 provided by the invention is a bacterial strain with a biological phosphorus removal function, can rapidly grow under the conditions of 150r/min and 30 DEG C, can effectively reduce the total phosphorus concentration of domestic sewage and an activated sludge system, can tolerate low temperature, and has a good phosphorus removal effect. And an effective technical means is provided for improving the biological phosphorus removal efficiency in the domestic sewage treatment proce
