👉 Thermolithobacteria are a type of bacteria that primarily thrive in environments where temperatures can fluctuate greatly, such as hot springs or hot springs thermal pools. These bacteria require extreme temperatures to survive and thrive, often reaching up to 100°C (212°F) or more. Thermolithobacteria are characterized by their ability to produce heat through photosynthesis, which is the process of converting sunlight into chemical energy in the form of glucose.
