Technical Specifications
| Organism | Lactobacillus delbrueckii subsp. lactis |
|---|---|
| Material Type | Microbial Strain |
| Preservation Form | Freeze dried pellet |
| Morphological Characteristics | For Gram positive bacteria, the MRS liquid culture medium is turbid, with a large amount of sediment at the bottom of the test tube. The growth of the Agar plate strain is weak, and it is recommended to use liquid culture |
| Culture Method | ① Prepare 1 liquid culture medium with a diameter of 18mm, approximately 10mL; ② Disinfect the surface of the ampoule tube, open it in a safe cabinet, burn the top with an alcohol lamp, quickly add sterile water to the burning area to break it, and then use tweezers to knock it open; ③ Take about 0.5mL of liquid culture medium and transfer it into a freeze-drying tube. After fully dissolving, take it back into the liquid culture medium in the test tube and mix well; ④ Place the liquid test tube under the specified "culture conditions" mentioned above for cultivation. If the bacterial liquid is turbid or there is a large amount of bacterial growth at the bottom, it can be used. |
