Detailed explanation-1: -The colon’s job is to dehydrate what’s left of the food and form it into stool. It does this by slowly absorbing water and electrolytes as its muscle system moves the waste along. Meanwhile, bacteria living in your colon feed on the waste and break it down further, completing the chemical part of the digestive process.
Detailed explanation-2: -Bacteria in the first, or ascending, part of the colon are experts in breaking down carbohydrates (sugars and starches). They do this by fermentation, whose byproduct is the gases that exit the back passage as wind.
Detailed explanation-3: -The main types of bacteria in the colon are obligate anaerobes, and the most abundant bacteria are members of the genus Bacteroides, anaerobic gram-positive cocci, such as Peptostreptococcus sp., Eubacterium sp., Lactobacillus sp., and Clostridium sp.
Detailed explanation-4: -Escherichia coli (E. coli) is the major species in the fecal coliform group.
