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 freeze dried culture shall be used up once and shall not be retained. The bacterial viability will resume after 1-2 generation of recovery and can be used normally. Handling instructions of agar slant and suspension liquid is enclosed. 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 :25-28 ℃, aerobic, integrated PDA. Comprehensive PDA: potato boiling juice 1000mL, potassium dihydrogen phosphate 3.0g, magnesium sulfate heptahydrate 1.5g, glucose 20.0g, vitamin B1 10mg, agar 20g,pH natural. 121 ℃,15min. Potato boiling solution: 200g of potato, peeled, cut into pieces, boiled in distilled water for 30min, constant volume of filtrate to 1000mL for later use. 121 ℃,15min.

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 for 5-7 days. You can also contact customer service for information "Inclined Transfer Method-Filamentous Fungi".

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

item	test result
viability	good viability, in 5 days plate colony is obvious
colony morphology:	Small filamentous fungi, colonies are obviously visible on comprehensive PDA culture medium, hyphae are white, have long slender hairs, and often split into teeth.
Conclusion:	good viability, no abnormal colony morphology, completely consistent with the above figure, qualified
