Liofilchem® Lactose for Bacteriological Use

The Liofilchem® Lactose for Bacteriological Use is a high-purity fermentable carbohydrate designed for microbiological applications. Serving as a key ingredient in fermentation tests and culture media, this lactose is free from other sugars, starch, proteins, and metals, ensuring consistent performance in laboratory and industrial settings.

Key Features:

1. Fermentable Carbohydrate:
   • Provides an energy source for bacterial metabolism.
   • Useful for differentiation tests, such as identifying lactose-fermenting bacteria like Escherichia coli from non-fermenters like Salmonella typhimurium.
2. High Purity:
   • Free from contaminants, including starch, proteins, metals, and other sugars.
   • Non-hygroscopic, ensuring stability and easy handling.
3. Wide Applications:
   • Suitable for use in fermentation studies and as an ingredient in dehydrated culture media.
4. Easy Solubility:
   • Fully dissolves in water at 5% concentration, simplifying media preparation.
5. Stable and Reliable:
   • Long shelf life of 4 years under proper storage conditions.

Physico-Chemical Characteristics:

Applications:

1. Fermentation Tests:
   • Distinguishes between lactose-fermenting and non-lactose-fermenting bacteria.
2. Culture Media Preparation:
   • Essential component of dehydrated culture media for microbial growth and metabolic studies.
3. Research and Industrial Microbiology:
   • Used in quality control, bacterial identification, and carbohydrate metabolism research.

Preparation and Storage:

• Preparation:
