Firmicutes

Firmicutes are a major group of bacteria that include many beneficial and some harmful species. They are characterized by their thick cell walls, which help protect them in various environments. These bacteria are found in the human gut, where they play important roles in digestion and overall health by helping break down food and produce essential nutrients. Firmicutes also exist in soil, water, and fermented foods, contributing to nutrient cycling and food production. Their balance with other bacteria influences health and disease, making them a significant focus in microbiology and medical research.
