Culture medium	7H10 agar medium (English name: 7H10): 0.5g ammonium sulfate, 1.5g potassium dihydrogen phosphate, 1.5g disodium hydrogen phosphate, 0.4g sodium citrate, 0.025g magnesium sulfate, 0.5mg calcium chloride, 0.001g zinc sulfate, 0.001g copper sulfate, 0.5g L-sodium glutamate, 0.04g ferric ammonium citrate, 0.001g pyridoxine hydrochloride, 0.5mg biotin, 0.25mg malachite green, 15.0g agar, absorb 5ml of glycerol and add 900ml of distilled water, heat, stir and dissolve, boil for 1 minute with a PH value of 6.4-6.8. High pressure sterilization at 121 ℃ for 10 minutes. When cooling 50-55 ℃, add 100ml of OADC additive for filtration and sterilization, mix well, and pour into a plate or test tube.
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 a flame, quickly drop sterile water to creak it, then 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 ℃;5-7 days; Aerobic
