Extreme thermophilic bacteria thrive at any temperature above 40/50°C. Thermotoga Maritima seems to be the bacteria that can survive at the highest temperature up to 90°C (reference 1, table 2). I wonder if there is a more exhaustive list of extreme thermophilic bacteria and if there is a known bacteria that can survive at higher temperatures than Thermotoga Maritima.
