Shell-shaped leather ear

Culture medium	Comprehensive PDA agar (CPDA): potato boil 1.0L, glucose 20.0g,KH2PO4 3.0g,MgSO4 · 7H2O 1.5g, vitamin B1 trace, agar 20.0g,pH 6.0±0.2. Sterilization at 121 ℃ for 15min. 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 ℃;5-7 days; Aerobic;
Storage conditions	2-8 ℃
morphology	Small filamentous fungi, with obvious colonies, white, dense and vigorous hyphae on the integrated PDA medium, spreading to the edge of the plate, and yellowish on the back of the medium.
application	Eat
Sharing mode	Public welfare sharing

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 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 lose of viability.

Growth Conditions :25-28 ℃, aerobic, integrated PDA,6d. Comprehensive PDA: potato boil 1.0L, glucose 20.0g,KH2PO4 3.0g,MgSO4 & middot;7H₂O 1.5g, vitamin B1 trace, agar 20.0g,pH 6.0 & plusmn;0.2.

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, 6 days, strain layer is obvious
colony morphology	small filamentous fungi have obvious colonies, white, dense and low flat on the integrated PDA medium, spreading and growing to concentric circles at the edge of the plate, and the back of the medium is light yellow.
conclusion	good viability, no abnormal colony morphology, qualified
