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 ℃, aerobic, LB broth medium. LB broth medium: peptone 10.0g, yeast powder 5.0g,NaCl 10.0g, distilled water 1.0L,pH7.0.
Recovery steps:
(1)Prepare a flask of LB liquid media
(2)Open it in 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 medium into the freeze dried ampoule,make the strain pellet fully dissolved. transfer the liquid suspension to the liquid media, and culture in plate shaker at 28℃ for 18-24 hours (140r/min);
Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:
item | test results |
viability | good viability,in 20h LB bacterial fluid is turbid, LB plate colony is obvious |
colony morphology: |
size: medium color: orange yellow shape: round edge: neat edge wet and dry: wet and smooth: smooth transparency: opaque bulge: middle bulge |
conclusion: | good viability, and colony morphology is not abnormal, completely consistent with the above figure, qualified |
