A glass flask is rinsed and autoclaved after use. It was then filled with sterile media in a sterile environment and covered. A few days, microbial growth appears in the flask. Assume the media and sterile environment is guaranteed to be sterile. What most likely caused the growth in the flask?
a. The flask has to be rinsed with bleach before autoclaving
b. A portion of the flask was not exposed to the steam
c. Autoclaves only sanitize equipment, so you cannot expect the flask to be sterile
d. Autoclaving inhibits growth, but does not kill microbes
