Imagine that you are an early microbiologist attempting to reproduce Louis Pasteur's famous experiments which helped disprove spontaneous generation. You first prepare a hay infusion (a type of nutrient broth), then boil it for 20 minutes in a swan-necked flask of the same design that Pasteur used. Upon cooling and incubation at room temperature, you notice that your broth has become cloudy (turbid) only a few days later. What did your broth contain that Pasteur's likely did not?Choose one:A. endosporesB. akinetesC. myxosporesD. sufficient oxygenE. sufficient nutrientsF. hyperthermophilic archaea
