Explain the Lactose Fermenters and Non lactose Fermenters

1) Lactose Fermenters - These produce acid on lactose fermentation, which results in red colouration on bacterial colony or surrounding medium. Example E.coli.

2) Non lactose Fermenters - These do not ferment lactose, so there is no production of acid and colonies appear uncoloured. Example: Salmonella, Shigella etc.
