Experiment

Oh. My. God.

Stinkiest experiment ever!
Worst week of my life - the experiment stank up the house so badly....
I found my initial hypothesis of meat accumulating the most fungi correct... at first. The beef very quickly had fungal growth, but the chicken had none. It smelt the worst out of every food, but no fungus so I conclude that the chicken had very heavy bacterial growth. But after the beef peaked its fungal growth, bacterial growth soon took over - it started to smell more like the chicken, it had the same kind of sticky white/yellow substance forming, and the fungus actually started to un-grow.

On day 4, some fungus started to grow on the oranges - this growth practically exploded the next day, with fungi 30 times the previous day. This growth then steadied, but still was far greater than any other material.

None of the vegetables had any fungal growth at all - they had dried up before fungus could begin growing. In other fungus-infected foods, the food was always quite moist. Once the veg dried up, it was no longer hospitable for fungus, nor bacteria and it did not decay.

The very cold temperatures during the experiment allowed only for the very best hosts for fungus and bacterial growth alike - although based on my observations, bacteria grew more easily and grew better than the fungus in the shade especially.

Oh I am so dreading doing this again. The chicken especially stank so badly - I will never forget that smell as long as I live. It was so strong! Such a small piece of chicken, and I could smell it from at least a metre away. Recording results was so hard on my poor nose...

  1. Yeah, I can imagine that that would smell rather awful. You need to make sure that you are actually consistently doing the work- it seems like you haven't posted for a while. What do your results look like? What are they showing?

    Make sure you do more research and that that research is making it on your blog!
