D)The thermal death point of Bacillus subtilis would be lower that of Staphylococcus aureus.

Question

Quizplus · Accepted Answer

Bacillus subtilis is a spore-forming bacterium, and spores are more heat-resistant than vegetative cells. Therefore, the thermal death point of Bacillus subtilis is typically higher than that of non-spore-forming bacteria such as Staphylococcus aureus.
