coliforms
一般描述
m-FC Agar is a selective membrane filtration medium suitable for the detection of fecal coliforms. The fecal coliforms derived from the intestinal tract of warm-blooded animals are differentiated from the other environmental coliforms due to their ability to grow at higher temperatures. The medium is supplemented with rosolic acid and incubated at 44.5 °C ± 0.2 °C for 24 h. Peptone and yeast extract, which serve as nutritious sources, and bile salts are added to inhibit accompanying Gram-positive flora. Lactose can be fermented by fecal coliforms at elevated temperatures to form blue colonies on the prepared medium (agar base with rosolic acid), whereas other organisms form grey colonies.
应用
m-FC Agar is used for the cultivation and enumeration of fecal coliforms by the membrane filtration technique.
