E. coli was grown on MacConkey Agar (MAC) at 37 degrees for 24 hour. MAC is a Selective and Differential media used to inhibit G+ growth and some G- bacteria as well as identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation produces pi... Read More
