The Possibilties of Mould

I would LOVE to do a project on evolution, psychology, or deep space... As it is, my best idea so far is fungus.

How To Kill Mould
with different temperatures

Step 1. Extract sample of mould. (Will probably come from pizza cheese or a peach; they are reliable sources in my experience.)
Step 2. Carefully grow mould onto nine slices of bread -as similar as I can get. Leave for five days until about equal growths of mould are seen on all the slices.
Step 3. Place three of the slices into the freezer (each in separate plastic freezer bags to protect surrounding food), three into the fridge, and the remaining three in room temperature conditions as a control.
Step 4. Examine differences in the rate of growth after a further five days.

I wanted to see how heat would affect mould, but due to recent spikes in electricty and gas costs I can't exactly leave the oven on for a week.

I've done some research today. Apparently:
1. Heat is often recommened to kill mould. Above 60 degrees Celcius would do.
2. Lukewarm conditions will allow the bacteria to grow faster.
3. Cold temperatures will not kill the bacteria, but will stop it from growing.
4. When temperature does not allow growth, mould can live in a dormant state before dying.
5. Different mould species very enormously in their tolerance of temperature and humidity.

"Moulds produce through spores, which can be asexual or sexual. Many species can produce both types, and many are able to survive extremes of temperature and pressure."

Still sounding good...?

  1. Stalking is not cool. >:(

    Unless of course the one doing the stalking is me.
