M-EC Test Agar 500G

M-EC Test Agar is recommended for testing Escherichia coli in water samples using membrane filter technique. It is used for the detection, differentiation and enumeration of Escherichia coli and coliforms in water using membrane filter technique. Filter the sample through a membrane filter. Place the membrane on M-EC Test Agar and incubate at 35 ± 0.5°C for 2 hours to rejuvenate injured or stressed bacteria and then incubate at 44.5 ± 0.2°C for 22 hours. Transfer filter to a filter pad saturated with urea substrate After 15 minutes, count yellow or yellow brown colonies using a fluorescent lamp and magnifying lens. E. coli produces yellow or yellow brown colonies
