Rhodococcus erythropolis
Culture medium Yeast glucose chloramphenicol agar medium (YGC): yeast extract 5.0g, glucose 20.0g, agar 15.0g (not included in liquid medium), chloramphenicol 0.1g, distilled water 1.0L. pH 6.6±0.2,121 ℃,15min sterilization.
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.

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, yeast glucose chloramphenicol agar medium, 18-24h. Yeast glucose chloramphenicol agar medium: 5.0 g of yeast extract, 20.0 g of glucose, 15.0 g of agar (not included in liquid medium), 0.1 g of chloramphenicol, and 1.0 L of distilled water. pH 6.6±0.2, 121℃, 15min sterilization.

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:

                                                             

 

item test results
viability: good viability,in 24 hours strain layer become obvious,  colony is typical on the streaked plate
colony morphology: (above)

size: 1-2mm ; Shape: round ; Edge: neat ; Transparency: opaque

color: orange ; Protuberance: middle bulge ; Surface: bright and smooth ; Texture: moist and easy to stir

Conclusion: good viability, no abnormal colony morphology, qualified
