Stachybotrys chartarum

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 a test tube containing 5~10mL of liquid medium and 2 plates; (2) Open it in the safety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps; (3) draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; (4) inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; ⑤ Put all the liquid test tubes and plates under the above culture conditions for cultivation, 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 on comprehensive PDA medium, light purple hyphae at the initial stage, light gray spores at the later stage, and flat The edge spreads and grows, and the back of the medium is black.
application	Research, quality control, positive control strain of GB/T 4789.16-Identification of Common Toxic Mould in 2003.
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 of agar plate 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, 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 of above mentioned plates;

(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 7-10days

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

Item	test results
viability	good viability, in 7days strain layer become obvious
colony morphology:	small filamentous fungi, with obvious colonies on integrated PDA medium, light purple hyphae at the initial stage, light gray spores at the later stage, spreading and growing to the edge of the plate, and black on the back of the medium.
Conclusion:	good viability, no abnormal colony morphology, qualified
