Weiyel Reference Materials
Subculture | Tryptone soybean medium (English name: TSA/TSB): tryptone 17.0g, soybean peptone 3.0g, sodium chloride 5.0g, dipotassium hydrogen phosphate 2.5g, glucose 2.5g, agar 20.0g (without liquid medium), distilled water 1.0L,pH 7.3±0.2. Sterilization at 121 ℃ for 15min. |
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 is a strong positive reference for heat inactivation for the evaluation of Salmonella enteritidis nucleic acid test for early diagnosis and quality control of infection. |
