Answer ( 1 )


    Salmonella does not ferment lactose because it lacks the necessary enzymes to break down lactose into simpler molecules that can be used for energy. Unlike other bacteria like Escherichia coli, which possess enzymes such as beta-galactosidase to ferment lactose, Salmonella does not produce these enzymes. As a result, Salmonella cannot utilize lactose as a carbon source for growth and energy production. Instead, Salmonella can utilize other nutrients present in its environment to survive and multiply.
