Product Description
Koser Citrate Medium is a specialized microbiological medium designed to determine the ability of bacteria to utilize citrate as their sole carbon source. This test is crucial in differentiating between bacterial species, particularly in clinical and research laboratories. The medium contains sodium citrate as the primary carbon source, along with inorganic ammonium salts as the nitrogen source. A pH indicator (bromothymol blue) is included to detect citrate utilization through a color change from green to blue.
This medium is widely used in microbiology labs for identifying enteric bacteria, especially in the differentiation of Salmonella and Shigella species. It is also employed in environmental and food microbiology to assess bacterial metabolic capabilities. The powder form allows for easy preparation and customization based on specific experimental requirements.
When preparing Koser Citrate Medium, it is essential to follow standard microbiological protocols to ensure accurate results. The medium should be sterilized by autoclaving before use, and proper aseptic techniques must be maintained during inoculation and incubation. Results are typically observed after 24 to 48 hours of incubation at 37°C.
For researchers and students working in microbiology, Koser Citrate Medium is an indispensable tool for bacterial identification and metabolic studies. Its reliability and ease of use make it a staple in both academic and professional laboratories.
