Abstract: The present disclosure discloses a methicillin-resistant staphylococcus aureus mutant strain and use thereof, and belongs to the field of molecular biology and microorganisms. The methicillin-resistant staphylococcus aureus mutant strain disclosed by the present disclosure has a relatively low exopolysaccharide synthesis ability and a relatively low biofilm metabolism ability, but it is sensitive to an antibiotic cefoxitin. The mutant strain can be used for treating a related disease caused by methicillin-resistant staphylococcus aureus infection through an endogenous ecological treatment strategy. The present disclosure provides a new idea for treating the disease.

Abstract: The invention discloses a portable generator comprising a case provided with a handle, and a generator set located in the case; a link span is affixed to the bottom of said case, the generator set is affixed to the link span through a cushion block, and a mounting arm extends upward on the top of the generator set, and is embedded in the top of the case through a cushion sleeve; the generator set of the invention is mounted in the case through the cushion block and the cushion sleeve, which is not only good in the cushion effect but also light in weight and convenient to mounting and maintaining.
