Yeperdoodles... (Yes :))
Yes, the bacteria in the large intestine feed on undigested material passing through and produce vitamins such as vitamin K and some B vitamins as byproducts of their metabolism. These vitamins are then absorbed by the body and play important roles in various physiological functions.
E. Coli
Yep
The colonic microflora in the large intestine help to synthesize certain vitamins. The primary function of the large intestine is to salvage energy from carbohydrate not digested in the upper gut.
Bacteria in the intestine feed on indigestible carbohydrates and as a byproduct produce certain vitamins. "Friendly" bacteria colonize the gut, preventing disease causing bacteria from finding places to colonize.
Large Intestine
The large intestine is attached to the posterior to the small intestine and as you maybe already know the small intestine is where food wastes go and bile is secreted into. The large intestine reabsorbs water from the ingested food particles before they enter the rectum and colon for excretion.
The large intestine helps maintain homeostasis by reabsorbing water, vitamins, minerals, and electrolytes during the process of forming feces that is excreted from the body through the last portion of the colon, the anus.
The large intestine absorbs water and electrolytes from undigested food material, forming feces. It also houses bacteria that aid in the fermentation of indigestible carbohydrates and the production of certain vitamins. Lastly, the large intestine helps to store and eliminate waste from the body.
In certain cases it is the large intestine. In others I haven't a clue.

The 3 main functions of the large intestine are: 1. Water reabsorption 2. Fermentation 3. Storing waste The small intestine is mostly responsible for digesting and absorbing nutrients. By the time food passes into the large intestine (colon), most nutrients and around 90% of water has already been absorbed. Nevertheless, the large intestine does play an important role in reabsorbing water and in maintaining water balance. The large intestine is full of bacteria, both good and bad, which ferment undigested food products. Eating certain types of food such as fiber, legumes, wheat, onions and fruit can lead to "excessive" production of gas. The bacteria breakdown these undigested products for their own nourishment. There is also a limited amount of absorption of some vitamins, such as vitamin K. Finally, the large intestine acts as a conduit or pathway for the passage of waste products from the small intestine to the anus. Removal of the large intestine (colectomy), either partial of total, is generally well tolerated by people with few side effects. There is no significant effect on nutrition, however water re-absorption may be affected and diarrhea can also sometimes occur.
