| Subculture | Nutritional gravy medium (English name: NA/NB): beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (not included in liquid medium), distilled water 1.0L,pH 7.0. Sterilization at 121 ℃ for 15min. [Note] Adding 5 mgMnSO4 · H2O to culture Bacillus is beneficial to produce spores. |
| Subculturing | Pick a single colony and add bacteria in a liquid triangular flask, then take 25mL of bacteria liquid and centrifuge to collect bacteria (centrifuge speed 8000r /min,30s), resuspend with 10mLPBS, and collect bacteria suspension for later use. The concentration of bacterial suspension is about 109CFU/mL, diluted to 10-6, 10-7, 10-8 gradient, take 200 μL coating count, select the colony number between 30 CFU to 300 CFU plate count; |
| Growth conditions | Culture temperature 37 ℃;18-24 hours; Aerobic gas environment; |
| Storage conditions | -80 ℃ |
| Safety level | 0 |
| Application | Accurate and rapid identification of pathogenic bacteria can effectively improve the pertinence and effectiveness of clinical treatment. This product uses heat-inactivated strong positive reference for the evaluation of Yersinia enterocolitica nucleic acid test for early diagnosis of infection And quality control. |
| Sharing mode | Public welfare sharing |
