Strongly lactose fermenting bacteria produce sufficient acid to cause precipitation of the bile salts, resulting in a pink halo in the medium surrounding individual colonies or areas of confluent growth. Bacteria with weaker lactose fermentation growing on MacConkey agar WebEMB agar is a selective culture medium for Gram-negative bacteria used primarily for the isolation and differentiation of lactose fermenting (forms colored colonies) and non-lactose fermenting (form colorless colonies) and the dye methylene blue in the medium inhibits the growth of gram-positive bacteria. 3. WebKlebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose - fermenting, facultative anaerobic, rod-shaped bacterium. It appears as a mucoid lactose fermenter on MacConkey agar .
