Clonostachys rosea

Subculture procedure	① Dissolve the frozen tube in a water bath (fungi at 30 ℃, bacteria at 37 ℃) 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.
Growth conditions	28 ℃; 5-7 days; aerobic;
Storage conditions	-80 ℃
Safety level	1
morphology	Small filamentous fungi have obvious white colonies and dense hyphae on the comprehensive PDA medium, spreading and growing towards the edge of the Agar plate. The back of the medium is light yellow
Sharing mode	Public welfare sharing

Clonostachys rosea

Storage conditions: 2~8 ℃

No. 356229

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: 28°C, aerobic, integrated PDA, 5 days. Comprehensive PDA: Potato cooking liquid 1.0L, glucose 20.0g, KH2PO4 3.0g, MgSO4 7H2O 1.5g, vitamin B1 trace, agar 20.0g, pH 6.0±0.2. Sterilize at 121℃ for 15min. Potato cooking liquid: Weigh 200g peeled potato pieces, boil in boiling water for 30min, collect the filtrate and dilute to 1.0L.

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 days plate colony is obvious
colony morphology: (above)	Small filamentous fungi have obvious colonies, white, dense and vigorous hyphae on the integrated PDA medium, spreading and growing to the edge of the plate, and the back of the medium is light yellow.
Conclusion	good viability, no abnormal colony morphology, qualified
