Slow lactose fermenters
Webb30 maj 2024 · How do you differentiate between lactose fermenter and non lactose fermenter on EMB? Organisms that are slow lactose-fermenters, produce less acid, and the colonies appear brown-pink. Non-lactose fermenters, increase the pH of the medium by deamination of proteins and produce colorless or light pink colonies.
