Product Format 提供形式 frozen

Type Strain 模式菌株 no

Comments 注釋 Food source, Rhynchomonas nasuta ATCC 50105, not supplied. Mixed bacteria present. Ultrastructural identity

Medium 培養(yǎng)基 ATCC? Medium 1361: Marine flagellate medium

Growth Conditions 生長條件

Temperature 培養(yǎng)溫度: 25.0℃

Cryopreservation Cryoprotective Solution

DMSO 2.0 ml

Fresh growth medium w/o bacteria 8.0 ml

1. Mix the components in the order listed. When the medium is added to the DMSO the solution will warm up due to chemical heat.

2. Harvest Stephanopogon cells or cysts from a culture that has recently passed peak density by filtration and centrifugation at 800 x g for 5 min.

3. Adjust the concentration of cysts at least 2 x 105/ml in fresh medium.

4. Mix the cell preparation and the cryoprotective solution in equal portions.

5. Dispense in 0.5 ml aliquots into 1.0 - 2.0 ml sterile plastic screw-capped cryules (special plastic vials for cryopreservation).

6. Place vials in a controlled rate freezing unit. From room temperature cool at -1℃/min to -40℃. If freezing unit can compensate for the heat of fusion, maintain rate at -1 C/min through heat of fusion. At -40℃ plunge ampules into liquid nitrogen. Alternatively, place the vials in a Nalgene 1℃ freezing apparatus. Place the apparatus at -80℃ for 1.5 to 2 hours and then plunge ampules into liquid nitrogen. (The cooling rate in this apparatus is approximately -1℃/min.)

7. Ampules are stored in either the vapor or liquid phase of a nitrogen refrigerator.

8. To establish a culture from the frozen state place the vial in a 35℃ water bath. Immerse the vial to a level just above the surface of the frozen material. Do not agitate the vial. Immediately after thawing, do not leave in water bath, aseptically remove the contents of the ampule and inoculate into a T-25 tissue culture flask containing 10 ml of an equal-parts mixture of ATCC medium 1525 and either ATCC medium 1405 or ATCC medium 1361, bacterized with Klebsiella pneumoniae subsp. pneumoniae (ATCC? 700831) or Enterobacter aerogenes (ATCC? 13048).

9. Aseptically transfer 1-2 ml from a thriving culture of Rhynchomonas to the T-25 flask. Incubate the culture at 25℃ with the cap screwed on tightly. Once the culture is established, follow the protocol for maintenance of culture.
