BeNa Culture Collection
Culture medium | YM medium (YM): yeast extract 3.0g, malt extract 3.0g, glucose 10.0g, peptone 5.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L,pH 6.2±0.2. 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. |
