Staphylococcus simulans

Culture medium	Nutritional gravy medium (NA/NB): beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (without liquid medium), distilled water 1.0L,pH 7.0. Sterilization at 121 ℃ for 15min. [Note] Adding 5 mg MnSO4 · H2O to culture Bacillus is beneficial to produce spores.
Subculture procedure	(1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) open it in the biosafety cabinet, heat the tip of ampoule in the flame, quickly drop sterile water to creak it, and break it with forceps; (3) draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; (4) inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; ⑤ Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.
Growth conditions	37 ℃;18-24 hours; Aerobic
Growth characteristics	On the Baird-Park agar plate, the colonies are gray and flat, with large colonies, with slight turbidity around and obvious transparent circles. On the blood agar plate, the colonies are white, dry and have hemolytic circles.
Storage conditions	2-8 ℃
morphology	The colony diameter is 1-2mm, round, with neat edges, opaque, white on the front, convex in the middle, bright surface, smooth surface, moist texture, easy to stir up, G + (blue-purple), cocci
Sharing mode	Public welfare sharing
