Agar Test pH 8.0 is specifically formulated to detect Aminoglycosides (such as streptomycin, neomycin, and kanamycin). The alkalinity of the medium (pH 8.0) is critical, as aminoglycosides reach their maximum antibacterial activity in basic environments. The medium serves as a base for the growth of a test organism, typically Bacillus subtilis (BGA). If the sample (e.g., meat tissue or kidney) contains residues of these specific antibiotics, a clear zone of growth inhibition (halo) will appear around the sample after incubation. The nutrient base, consisting of Peptone and Meat Extract, ensures a dense and uniform lawn of bacterial growth for high-contrast results.
Advantages
- Targeted Sensitivity: Specifically adjusted to pH 8.0 to maximize the detection of aminoglycoside antibiotics.
- Standardized Testing: Complies with official methods for the microbiological screening of inhibitory substances in meat.
- Clear Interpretation: Provides a highly reproducible growth background, making the measurement of inhibition zones simple and accurate.
- High-Quality Components: Formulated with pure ingredients to ensure no endogenous inhibitory effects from the agar itself.
- System Integration: Designed to be used alongside Agar Test pH 6.0 and pH 7.2 to provide a comprehensive antibiotic profile.
