Description
Lactose Bile Salt Fermentation broth Medium Tubes (3x)
The Lactose Bile Salt Fermentation broth Medium Tubes are specifically designed for the detection and enumeration of coliform bacteria. Each box contains 20 individually packaged tubes of 5 ml each, ensuring superior contamination protection and preventing leakage. With a shelf life of six months, these tubes are a reliable choice for laboratories focusing on microbial analysis.
Product Features
This fermentation medium is expertly formulated to support the growth of coliforms while inhibiting gram-positive bacteria. The protein peptone serves as both a carbon and nitrogen source, fulfilling the metabolic requirements of bacteria. Bile salts are included in the formulation to suppress the growth of unwanted gram-positive organisms, thereby enhancing the specificity of your results.
Key Ingredients:
- Protein Peptone: Provides essential carbon and nitrogen for bacterial growth.
- Bile Salts: Effectively inhibit gram-positive bacterial growth.
- Lactose: A fermentable carbohydrate specifically targeting coliform bacteria.
- Bromcresol Purple: A pH indicator that turns yellow in acidic conditions and purple in alkaline conditions, allowing for easy visual assessment of fermentation.
Microbial Sensitivity Testing
The Lactose Bile Salt Fermentation Medium Tubes (3x) enable precise microbial sensitivity testing. Inoculate the medium with the following quality control strains and incubate at 36 ± 1°C for 24 ± 2 hours:
| Quality Control Strain | Strain Number | Inoculum Amount (CFU) | Growth Condition | Result |
|---|---|---|---|---|
| Escherichia coli | ATCC 25922 | 10 – 100 | +++ | Acid and gas production |
| Salmonella typhimurium | ATCC 14028 | 10 – 100 | +++ | Turbid with no gas production |
| Enterococcus faecalis | ATCC 29212 | 1000 – 5000 | – | Inhibited |
| Citrobacter freundii | ATCC 43864 | 10 – 100 | +++ | Acid and gas production |
| Enterobacter cloacae | ATCC 23355 | 10 – 100 | +++ | Acid and gas production |
| Enterobacter aerogenes | ATCC 13048 | 10 – 100 | +++ | Acid and gas production |
