No.185706
Product format: agar slant in 14mm test tube
Validity: growing culture in 30days
Biosafety y level: 1, handle in ultra-clear table or safety cabinet
Receiving notice: if any abnormality is found on the day of receipt, please contact the customer service within 24 hours. If it is overdue, it is deemed that the bacteria are well. The agar slant can be used directly. In principle, it can be used many times without contamination within the validity period, but viability will gradually decrease with time. 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°C, aerobic, integrated PDA, 5-7 days. Comprehensive PDA: Potato cooking liquid 1.0L, glucose 20.0g, KH2PO4 3.0g, MgSO4 7H2O 1.5g, trace amount of vitamin B1, agar 20.0g, pH 6.0±0.2. Sterilize at 121℃ for 15min. Potato cooking liquid: Weigh 200g of peeled potato pieces, boil in boiling water for 30min, collect the filtrate and dilute to 1.0L.
Recovery steps:
① Prepare 1-2 pieces of PDA plates;
② Sterilize the surface of test tube for the agar slant, open it in the biosafety cabinet;
③ Cut into the pieces with aseptic inoculation hoe and inoculation shovel (see attached page). the size of square pieces is 0.5 × 0.5cm²;
④ Lay flat the small pieces to the center of the agar plate;
⑤ Put the plates under the above culture conditions, 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 5days strain layer become obvious |
| colony morphology: | small filamentous fungi, the colony is obvious on the comprehensive PDA medium, the colony is gray-black on the front, the edge is light yellow to white, and the back is light yellow. |
| Conclusion: | good viability, no abnormal colony morphology, qualified |
