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: 30 ℃, aerobic, 7H10 agar medium. For 2-3 days, 7H10 agar medium: 0.5g of ammonium sulfate, 1.5g of potassium dihydrogen phosphate, 1.5g of disodium hydrogen phosphate, 0.4g of sodium citrate, 0.025g of magnesium sulfate, 0.5mg of calcium chloride, 0.001g of zinc sulfate, 0.001g of copper sulfate, 0.5g of sodium L-glutamate, 0.04g of ferric ammonium citrate, 0.001g of pyridoxine hydrochloride, 0.5mg of biotin, 0.25mg of malachite green, 15.0g of agar, 5ml of glycerol and 900ml of distilled, heat, stir and dissolve, boil for 1 minute with a PH value of 6.4-6.8. High pressure sterilization at 121 ℃ for 10 minutes. When cooling 50-55 ℃, add 100ml of OADC additive for filtration and sterilization, mix well, and pour into a plate or test tube.
Note: OADC additive preparation (100ml): 5g of bovine albumin (component v), 0.06ml of oleic acid, 2g of glucose, 0.003g of enzyme and 0.85g of sodium chloride.
Recovery steps:
(1)Prepare a test tube containing 5-10mL of liquid culture medium and 2 plates;
(2) Open the ampoule 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:
Size: 1-2mm Shape: Round Edge: Irregular Transparency: Opacity
color: light yellow uplift: flat surface: rough texture: dry and difficult to pick
