Lactose is a disaccharide composed of glucose and galactose. Its fermentation is a key biochemical characteristic used to distinguish between different groups of bacteria. For example, "lactose fermenters" (like Escherichia coli) produce acid when grown on media containing lactose, causing a color change in pH indicators (e.g., in MacConkey Agar or CLED Agar). As a Pharmacopoeia-grade (EP) ingredient, this product ensures the highest level of purity, with strictly controlled limits on impurities, moisture content, and microbial contamination, making it suitable for both diagnostic microbiology and pharmaceutical fermentation processes.
Advantages
- EP Compliance: Meets the rigorous quality standards of the European Pharmacopoeia, ensuring reliability in regulated laboratory environments.
- Standardized Differentiation: Provides consistent and reproducible results in biochemical tests used to identify coliforms and other enteric pathogens.
- High Purity: Strictly controlled for the absence of inhibitory substances that could affect microbial growth or enzymatic activity.
- Versatile Application: Used as a primary carbon source in diverse media such as Lactose Broth, Brilliant Green Bile Broth, and various chromogenic agars.
- Excellent Solubility: Dissolves readily in water, facilitating the preparation of clear and consistent culture media.
