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 the plate and open it in biosafety cabinet; (3) Absorb 1-3ml of sterile water into the plate, scrape the bacterial lawn back and forth on the surface of the plate with a sterile spreader to make a bacterial suspension; (4) suck the bacteria suspension with a pasteur pipette, dispense it into a fresh plate evenly. (5) put the plates under the growth conditions.
Growth conditions	28 ℃;5-7 days; Aerobic
Storage conditions	2-8 ℃
morphology	Small filamentous fungi, with obvious colonies on comprehensive PDA medium, white hyphae at the initial stage, light yellow spores at the later stage, light color and dark color
application	For the detection of griseofulvin-M87
Sharing mode	Public welfare sharing

Microsporum gypseum

Storage conditions : 2~8 ℃

No. : 340196

Product format: agar slant in 14mm test tube

Validity period : growing culture in 30 days

Biosafety level : 1 , handle in ultra-clean 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 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 :28 ℃, aerobic, integrated PDA,5-7 days. Comprehensive PDA: potato boiling juice 1000mL, potassium dihydrogen phosphate 3g, magnesium sulfate 1.5g, glucose 20g, vitamin B1 10mg, agar 20g,pH natural. 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, 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 5-7 days strain layer is obvious
colony morphology	small filamentous fungi have obvious colonies, white hyphae, dense and vigorous on the integrated PDA medium, spreading and growing to concentric circles at the edge of the plate and not producing spores
conclusion	good viability, no abnormal colony morphology, qualified & nbsp;
