Microbes are often identified using biochemical tests that detect specific enzymes of metabolic pathways. e. coli typically ferments lactose, whereas the dysenterybacterium, shigella, does not. if a pure culture of each bacterium were placed in a tube containing lactose as the only food source, and a chemical indicator changed color if the tube became acid, what would the tubes look like after the bacteria were incubated?
