These symptoms happen due to undigested lactose that ferments in the colon, which eventually leads to an overgrowth of bacteria, causing gas and other problems. Diarrhoea is a common symptom of ...

In the presumptive test, 9 different tubes of lactose broth with 10 fold variations of the water sample are inoculated. If any lactose-fermenting bacteria grow and produce gas, the medium will turn ...
