What is the predominant indigenous biota of the colon?

Explanation:
The colon is a highly anaerobic environment, so its resident microbes are predominantly anaerobes. Among these, the most abundant group are gram-negative, nonspore-forming anaerobes such as Bacteroides, which are well adapted to fermenting complex carbohydrates in the gut. This combination—anaerobic lifestyle with gram-negative, nonspore-forming characteristics—best describes the major indigenous biota of the colon. While there are anaerobic gram-positive organisms and some spore-formers in the colon, they are not the dominant residents, and aerobic bacteria are less common in this low-oxygen habitat.
