Bacterial colony formations exhibit diverse morphologies and dynamics. A mechanistic understanding of this process has broad implications to ecology and medicine. However, many control factors and their impacts on colony formation remain underexplored. Here we propose a reaction-diffusion based dyna …

It is 1-3 x 0.4-0.7 µm in size and 0.6 to 0.7 µm in volume. It is arranged singly or in pairs. Colony morphology on CLED. Enteric bacteria on CLED agar. Bacteria who utilize lactose form yellow colonies on CLED (typically E.coli, Klebsiella pneumoniae, Enterobacter cloacae). Bacteria who don't utilize lactose (typically Salmonella spp., Shigella, Proteus spp.) form blue-green colonies on the surface of CLED agar. Escherichia coli (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə ˈ k oʊ l aɪ /), also known as E. coli (/ ˌ iː ˈ k oʊ l aɪ /), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).
