Subculture procedure	① Prepare 1-2 of the above plates; ② Open the safety cabinet, burn the top with an alcohol lamp, quickly drip sterile water to break it, and then use tweezers to crush it; ③ Take 0.5mL of sterile water and transfer it into a freeze-drying tube. After fully dissolving the bacterial powder, transfer it into two plates, each Agar plate containing about 200 μ L, and apply evenly; ④ Place the petri dish under the above cultivation conditions for cultivation, and once the bacterial strain grows, it can be used.
Growth conditions	37 ℃; 24-48 hours; aerobic
Storage conditions	2-8 ℃
Safety level	1
morphology	The colonies were 1-2 mm in diameter, circular with an entire margin, and opaque. They were creamy-white in color, convex in elevation, and displayed a smooth, glistening, moist, and easily liftable surface. Microscopic examination revealed Gram-positive (blue-violet) bacilli. The culture was pure.
