VRBG Agar

VRBG Agar, the ultimate culture medium formulated specifically for isolating Enterobacter sakazakii in milk powder. This high-quality agar is essential for microbiology laboratories dedicated to food safety testing and product quality assurance, adhering to FDA and SN methods.

Key Components for Optimal Performance

VRBG Agar features a balanced mix of essential nutrients that promote the growth of enteric bacteria. The formulation includes:

• Peptic Digest of Animal Tissue (7.0 g/L): This component provides vital nutrients for bacterial growth.
• Yeast Extract (3.0 g/L): It enhances microbial growth and nutrient absorption.
• Sodium Chloride (5.0 g/L): This maintains osmotic balance, which is crucial for cell integrity.
• Glucose (10.0 g/L): Serves as a primary energy source for microbial metabolism.
• Bile Salts (1.5 g/L): These selectively inhibit non-enteric bacteria while promoting the growth of Enterobacter sakazakii.
• Crystal Violet (0.002 g/L) and Neutral Red (0.03 g/L): These indicators help differentiate bacterial colonies.
• Agar (15.0 g/L): Provides a solid matrix for effective culture growth.
• Lactose (10.0 g/L): Facilitates the differentiation of lactose fermenters, enhancing the isolation process.

Optimal pH for Reliable Results

With a final pH of 7.4±0.2 at 25℃, VRBG Agar ensures precision, making it a trusted choice for microbiologists focused on isolating pathogens in food products.

Simple Preparation for Convenience

Preparing VRBG Agar is easy: simply suspend 51.5 g in 1 L of distilled water, boil for no more than two minutes—no autoclaving required. For the best results, use the prepared medium within three hours.

Why Choose VRBG Agar?

By choosing VRBG Agar, you prioritize accuracy and compliance in microbiological testing. This specialized culture medium plays a vital role in isolating Enterobacter sakazakii, a significant pathogen in milk powder. Ensure your laboratory meets health regulations and maintains high safety standards.
