Does all bacteria have the same growth temperature?

No; like all life on Earth, different organisms colonise different ecological niches. Enterococcus bacteria like to grow at body temperature, around 37 degrees Celsius. However, Thermophila bacteria can survive in hot springs which are at over 90 degrees Celsius. For interest, 'entero' refers to the gastrointestinal tract whilst 'thermophila' means 'likes heat'.
