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.
