Description

Lactose Broth is a specialized microbiological culture medium formulated for the enrichment and detection of coliform bacteria, particularly in food, water, and pharmaceutical samples. Its core value lies in providing a selective environment that supports the growth of target organisms while facilitating their identification through specific metabolic reactions. This product is essential for quality control laboratories in the food and beverage, pharmaceutical manufacturing, and water treatment industries to ensure product safety and regulatory compliance.

Application

• Microbiological Quality Control in food production facilities for the detection of coliforms and Escherichia coli.
• Water Safety Testing for the presumptive identification of fecal contamination in drinking and environmental water samples.
• Pharmaceutical Raw Material Testing as part of microbial limit tests for non-sterile products.
• Dairy Industry Sanitation Monitoring to verify the effectiveness of cleaning and sanitization procedures.
• Clinical and Diagnostic Microbiology for the isolation and study of lactose-fermenting enteric bacteria.
• Beverage Production to ensure the absence of indicator organisms in final products like juices and bottled water.

Quality Control

Our Lactose Broth is manufactured under strict quality management systems. Each batch undergoes rigorous performance testing, including growth promotion and selectivity checks against standard reference strains to ensure consistent and reliable results. Certificates of Analysis (COA) detailing pH, sterility, and performance characteristics are available upon request. The formulation meets the specifications outlined in recognized compendia such as the USP, EP, and ISO standards for culture media.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. The product is hygroscopic (moisture-sensitive); ensure the container is kept sealed in a low-humidity environment to prevent clumping and maintain performance stability. Keep away from direct heat sources.
