Issatchenkia orientalis

Culture medium	YM medium (YM): yeast extract 3.0g, malt extract 3.0g, glucose 10.0g, peptone 5.0g, agar 20.0g (without liquid medium), distilled water 1.0L,pH 6.2±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.

Issatchenkia orientalis

Storage conditions : 2~8 ℃

No. : 337336

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 and can be used normally. 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 :25-28 ℃, aerobic, YM medium. YM medium: yeast extract, 3.0g malt extract, 3.0g glucose, 10.0g protein block, 5.0g agar, 20.0g distilled water 1000 ml ,pH 6.2 +/- 0.2,121 ℃,15min.

Recovery steps:

(1)Prepare 1-2 of YM plates;

(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 sterile water into the freeze dried ampoule, make it fully dissolved, and distribute the solution to the YM plates well in 200ul/plate;

(4)Put the plates under the above culture conditions for cultivation for 24-48 hours.

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

item	test result
viability	good viability, in 40h YM strain layer is obvious
colony morphology	size: general color: milky white shape: round edge: neat and wet edges: slightly dry and smooth: slightly rough transparency: opaque protuberance: bulge
conclusion	good viability, and colony morphology is not abnormal, completely consistent with the above figure, qualified
