Which organisms would MOST likely be isolated from aerobic growth conditions with acetate and a soil sample heated to 80°C for 10 min?

D) mycoplasmas

Question

Endospore-forming bacteria can survive extreme conditions, such as high temperatures, due to their ability to form spores. Heating the soil sample to 80°C would likely kill non-spore-forming organisms, leaving endospore-formers as the most likely survivors.
