BeNa Culture Collection
Culture medium | Glucose nutrition agar -1(G-NA-1): nutrition agar plus glucose medium: peptone 30.0g, glucose 1.0g, beef paste 5.0g,NaCl 5.0g, agar 15g (not included in liquid medium), distilled water 1.0L,pH7.2,121 ℃,15min sterilization. |
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. |

Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:
Item | test results |
viability | good viability,in 20 hours,liquid medium become turbid, obvious strain layer occurs on the plate; colony is typical on marked plate |
colony morphology: (above) |
size: 2-4mm shape: round edge: irregular transparency: opaque color: light yellow uplift: flat surface: rough gray texture: dry |
Conclusion | good viability, no abnormal colony morphology, qualified |
