Culture medium MRS medium (MRS): peptone 10.0g, beef paste 10.0g, yeast powder 4.0g, glucose 20.0g, magnesium sulfate 0.2g, sodium acetate 5.0g, triammonium citrate 2.0g, dipotassium hydrogen phosphate 2.0g, manganese sulfate 0.04g, Tween 80 1.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L. pH 5.7±0.2. Sterilization at 121 ℃ for 15min.
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 37 ℃,24-48h, anaerobic
Storage conditions 2-8 ℃

No.: 135265

Product format : freeze dried,200ul

Validity period: 6 years

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.

Growthconditions :37 ℃, anaerobic, MRS medium, 18-24h. MRS medium: peptone 10.0g, beef paste 10.0g, yeast powder 4.0g, glucose 20.0g, magnesium sulfate 0.2g, sodium acetate 5.0g, triammonium citrate 2.0g, dipotassium hydrogen phosphate 2.0g, manganese sulfate 0.04g, Tween 80 1.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L. pH 5.7±0.2. Sterilization at 121 ℃ for 15min.

Recovery steps:

(1)Prepare sterile test tube of 5-10ml liquid medium and 2 plates; Silica gel plug is used for liquid test tube culture medium to ensure ventilation and facilitate deoxygenation. Please put the liquid medium and plate in an anaerobic environment for 24h before usage.

(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 liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly;

(4)Put the plates under the above culture conditions for cultivation for 18-24 hours.

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

                                                

item test result
viability good viability, in 18-24h liquid medium become turbid, obvious strain layer occurs on the plate,colony is typical on marked plate.

colony morphology:
