LBM 93.03.067 Enterobacter

Culture medium	Tryptone soybean medium (TSA/TSB): tryptone 17.0g, soybean peptone 3.0g, sodium chloride 5.0g, dipotassium hydrogen phosphate 2.5g, glucose 2.5g, agar 20.0g (without liquid medium), distilled water 1.0L,pH 7.3±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 biosafety cabinet, heat the tip of ampoule in the flame, quickly drop sterile water to creak it, and 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.

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: 30℃, aerobic, peptone soybean medium, 18-24h. Peptone soybean medium: peptone 17.0g, peptone 3.0g, sodium chloride 5.0g, dipotassium hydrogen phosphate 2.5g, glucose 2.5g, agar 20.0g(not included in liquid medium), distilled water 1.0L, pH 7.3±0.2. Sterilization conditions: 121℃, 15min.

Recovery steps:
(1)Prepare a test tube containing 5-10mL of liquid culture medium and 2 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 result
viability:	good viability,in 20 hours liquid medium become turbid, obvious strain layer occurs on the plate,colony is typical on marked plate.
colony morphology: (above)	size: 1-2mm shape: round edge: neat transparency: translucent color: milky white uplift: flat surface: bright and smooth texture: moist and viscous
Conclusion:	good viability, no abnormal colony morphology, qualified
