Monascus sp.

Subculture procedure	① Dissolve the frozen tube in a water bath (fungi at 30 ℃) and shake quickly for dissolution; ② Wipe the outer wall of the cryovial with an alcohol swab for disinfection, and then transfer it to a safe cabinet for operation; ③ Unscrew the tube cap, aspirate all the dissolved solution, and transfer it into 1-2 agar plates (each plate contains approximately 200 μL, and for anaerobic bacteria cultivation, the culture medium needs to be placed in an anaerobic environment for 24 hours to remove oxygen); ④ After spreading evenly, transfer to the above cultivation conditions for cultivation.

Monascus purpureus Went

Storage conditions: 2~8 ℃

No. 354889

Product format: agar slant in 14mm test tube

Validity period: growing culture, in 30 days

Biosafety level: 1, handle in ultra-clear 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 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, PDA agar, 5-7 days, PDA agar: potato boil 1.0L, glucose 20.0g, agar 15.0g, natural pH. Sterilization at 121 ℃ for 15min. Potato boiling solution: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect filtrate to a constant volume of 1.0L.

Recovery steps:

(1) Prepare 2 of above mentioned plates;

(2) Open it in the biosafety 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.

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 plate bacteria layer is obvious
colony morphology: (above)	filamentous fungi, with obvious bacterial layer on PDA medium, white and dense hyphae, vigorous spread and growth of hyphae, and red hyphae in later stage.
Conclusion	good viability, no abnormal colony morphology, qualified
