Detailed explanation-1: -With the advent of antibiotics and germ-free animals, it was demonstrated that the resident bacteria in the gut play a large role in preventing pathogens from colonizing and causing disease, in animals and humans.
Detailed explanation-2: -The colon houses trillions of bacteria that protect our gut and produce vitamins. The bacteria in the colon produce substantial amounts of vitamins by fermentation. Vitamin K and B vitamins, including biotin, are produced by the colonic bacteria. These vitamins are then absorbed into the blood.
