EMB, Mannitol, and MacConkey Agar

We streaked EMB, Mannitol, and MacConkey agar plates with our unknown bacteria L 25, and determined that since our bacteria was pinkish on the EMB plate,  it is a gram-negative enteric bacteria, with a lower acid production because it only partially ferments lactose. The mannitol plate was negative, our bacteria does not ferment mannitol. Our MacConkey agar plate confirmed that our gram-negative enteric bacteria partially ferments lactose. It is a facultative anaerobe which oxideses H202, which means it has catalase. Hopefully next week, we will identify it!
