Acidozymes

Definition

Acidozymes are a type of extremophile enzyme that thrive in highly acidic environments, often found in places like acid mine drainage or geothermal hot springs. These enzymes are adapted to function optimally at low pH levels, enabling organisms to survive and flourish in extreme conditions where most life forms cannot. Their unique properties make them important for biotechnological applications, such as bioremediation and industrial processes.
