Description:
Penicillin G (16 µg/mL) Nutrient Agar Plates are designed for the selective cultivation and isolation of bacteria from a wide range of clinical, food, dairy, and environmental samples. The addition of Penicillin G at 16 µg/mL provides effective inhibition of susceptible Gram-positive bacteria, making these plates valuable for applications where the suppression of penicillin-sensitive organisms is desired or for screening penicillin-resistant strains.
Nutrient Agar is a versatile, non-selective medium The medium’s clarity and stability make it ideal for teaching, demonstration, and routine laboratory use, as it resists overgrowth and supports prolonged culture viability at ambient temperatures.
The medium can be further enriched with biological fluids such as horse or sheep blood to cultivate fastidious organisms. The inclusion of Penicillin G enhances selectivity, allowing for differentiation between penicillin-sensitive and resistant bacteria, which is particularly useful in clinical diagnostics, research, and antimicrobial susceptibility testing.
Applications:
-
Selective isolation and screening of penicillin-resistant bacteria
-
Suppression of penicillin-sensitive Gram-positive organisms in mixed cultures
-
Microbiological analysis of clinical, food, dairy, and water samples
-
Teaching and demonstration of antibiotic selection in microbiology
Key Benefits:
-
Inhibits growth of penicillin-sensitive bacteria, enabling targeted isolation and study
-
Suitable for a wide range of specimen types
-
Ready-to-use, stable, and convenient for laboratory workflows
-
Can be further enriched for specialized applications
Penicillin G (16 µg/mL) Nutrient Agar Plates are an essential tool for laboratories requiring selective cultivation, antibiotic screening, and reliable bacterial isolation in clinical, food, and environmental microbiology.
