Potato boiling liquid: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect the filtrate to a constant volume of 1.0L.
Subculture procedure	(1) Prepare 1-2 pieces of the plate; (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.
Growth conditions	28°C;5-7 days; Aerobic;
morphology	Small filamentous fungi, the colony is obvious on the comprehensive PDA medium, the colony is low and flat, white, and the back of the medium is light yellow.

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: 28°C, aerobic, synthetic 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 of above mentioned plates（place in anaerobic environment for 24hours before usage）；

(2) Open it in the biosafety cabinet, sterilize of the ampoule, heat the tip in a flame, quickly drop sterile water to creak it, then break it with forceps;

(3) Draw 0.5ml of sterile water into the freeze dried ampoule, make it fully dissolved, and distribute the solution to the plates well in 200ul/plate;

(4) Put the plates under the above culture conditions for cultivation for 5-7 days.

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

Item	test results
viability	good viability, in 7 days plate colony is obvious
colony morphology	small filamentous fungi have obvious colonies on the integrated PDA medium, with low and flat colonies, white, and light yellow on the back of the medium
conclusion	good viability, no abnormal colony morphology, qualified
