GENERAL HISTOLOGY

Detailed explanation-1: -Cellulolytic bacteria are key participants in this breakdown process of cellulose, which is otherwise indigestible by the host. They critically contribute to host nutrition and health through the production of short-chain fatty acids, in addition to maintaining the balance of intestinal microbiota.

Detailed explanation-2: -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-3: -The bacteria Fibrobacter succinogenes, Ruminococcus flavefaciens, and Ruminococcus albus generally are regarded as the predominant cellulolytic microbes in the rumen.

Detailed explanation-4: -The human large intestine contains a microbiota, the components of which are generically complex and metabolically diverse. Its primary function is to salvage energy from carbohydrate not digested in the upper gut.

Detailed explanation-5: -Bacteria digest cellulose. TRUE. Specialized bacteria in the rumen secrete enzymes that are able to digest cellulose which normal human digestive enzymes cannot.
