What bacteria can survive in hot water?

Some bacteria can survive at very high temperatures. These types of bacteria are called thermopiles, which means “heat loving.” Thermophiles are harmless to humans and grow best at temperatures between 113 to 176°F (45 to 80°C). They’re often found in hot springs and in hydrothermal vents deep in the ocean.
