Obligate anaerobes

Obligate anaerobes are microorganisms that cannot survive in the presence of oxygen. Instead, they thrive in environments where oxygen is absent, such as deep soil, underwater sediments, or inside the intestines of animals. These organisms rely on alternative processes for energy production, like fermentation, to grow and reproduce. While they are crucial for various ecological processes, such as breaking down organic matter, their inability to tolerate oxygen means they can be sensitive to changes in their environment. Understanding obligate anaerobes helps us appreciate their role in ecosystems and in applications like waste treatment and bioenergy.
