Inspired by Louis Pasteur's swan-neck flask experiment, a microbiology student was interested in repeating this experiment using hay infusion instead of Nutrient broth. He placed a few strands of dried grass in a swan-neck flask containing sugar solution and boiled it for 30 minutes. After 3 days of incubation at room temperature, he noticed bacterial growth in the flask. Does this experiment support spontaneous generation?

No, this doesn't support spontaneous generation ...

Explanation:

Although their are bacteria present on the media but the hay infusion techniques are only used for cilliates like Paramecium. So, the bacterial growth was due to mishandling and some possible source of contamination is also involved. Finally, because of these facts this experiment doesn't support spontaneous generation in any case.
