Slow lactose fermenters

Some organisms ferment lactose slowly or weakly, and are sometimes put in their own category. These include Serratia [6] and Citrobacter. [7] Mucoid colonies [ edit] Some organisms, especially Klebsiella and Enterobacter, produce mucoid colonies which appear very moist and sticky and slimy.
