Louis Pasteur's classic swan-necked flask experiment might not have disproved spontaneous generation if this microbial type was present:

Quizplus · Accepted Answer

Endospore forming microbes are capable of surviving harsh environmental conditions, so they could have potentially survived the boiling process and grown once nutrients were introduced into the flask, leading to the appearance of spontaneous generation. Both aerobic and anaerobic microbes would have been killed in the boiling process, and viruses are not considered living organisms and would not have impacted the experiment.
