Pseudomonas stutzeri

Culture medium	Nutritional gravy medium (NA/NB): beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (without liquid medium), distilled water 1.0L,pH 7.0. Sterilization at 121 ℃ for 15min. [Note] Adding 5 mg MnSO4 · H2O to culture Bacillus is beneficial to produce spores.
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.

Storage conditions	2-8 ℃
morphology	Size: general color: orange shape: round edge: neat edge Wet and dry: moist smooth: smooth transparency: opaque uplift: low concave
Separation substrate	Human cerebrospinal fluid
application	Type strains, classification studies, reduction of pyrimidines

Pseudomonas stutzeri

Storage conditions : 2~8 ℃

No. : 337008

Product format: freeze dried, 200ul

Validity period : freeze-dried tube 24 months

Biosafety level : 1 , handle in ultra-clean 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. 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.

Recovery/subculture :37°C, strictly aerobic, nutritious agar/gravy medium (NA/NB). Nutritional agar medium: beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L,pH7.0. 121 ℃, 15min.

Recovery steps:

(1)Prepare a flask of NB liquid media or two NA agar plates.

(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 37℃ (140r/min); or directly dispense 200ul of the liquid suspension into a NA agar plate evenly, then place the plate under the above conditions.

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

item	test result
viability:	good viability, in 20h,NB bacterial fluid is turbid; The bacterial liquid is marked with NA plate, and strain layer is obvious
colony morphology:	size: general color: orange yellow shape: round edge: neat edge wet and dry: wet and smooth: smooth transparency: opaque uplift: low convex
Conclusion:	good viability, and colony morphology is not abnormal, completely consistent with the above figure, qualified
