Streptomyces prasinus

Culture medium	Gauche Synthesis No. 1 Agar (GM): 20g of soluble starch, 0.5g of sodium chloride, 0.01g of ferrous sulfate, 1.0g of potassium nitrate, 0.5g of dipotassium hydrogen phosphate, 0.5g of magnesium sulfate, 15g of agar, 1.0L of distilled water and 7.3±0.2 of pH. Sterilization at 121 ℃ for 15min.
Subculture procedure	(1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) Open it in the safety 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	28 ℃,3-5 days, aerobic

Please operate in strict accordance with this instruction, otherwise the replacement of bacteria are not be available in case of aberrant growth and loss of viability.

Growth conditions: 28 ℃, aerobic, Goblet synthesis No. 1 agar, 3-5 days. Gao's Synthesis No. 1 Agar: 20g of soluble starch, 0.5g of sodium chloride, 0.01g of ferrous sulfate, 1.0g of potassium nitrate, 0.5g of dipotassium hydrogen phosphate, 0.5g of magnesium sulfate, 15g of agar, 1.0L of distilled water, pH 7.3±0.2. Sterilization at 121 ℃ for 15min.

Recovery steps:

(1)Prepare 1-2 of above mentioned plates;

(2)Open it in the biosafety cabinet, sterilize of the ampoule, heat the tip in a flame, quickly drop sterile water to creak it, then break it with forceps;

(3) draw 0.5ml of sterile water into the freeze dried ampoule, make it fully dissolved, and distribute the solution to the plates well in 200ul/plate;

(4) Place all the plates under the above culture conditions, and the strains can be used when they grow out.

Recovery record: According to the recovery instructions, the results of the recovery are reported as follows

Item	test results
viability:	good viability, in 3-5 days strain layer become obvious;colony is typical on the streaked plate
colony morphology: (above)	Size: 2-4mm Shape: Round Edge: Untidy Transparency: Opaque Color: Light Yellow Bulge: Flat Surface: Rough and wrinkled Texture: Dry and firm
