This is your brain. This is your brain on Microbiology…

In an effort to eat a relatively healthy diet, I occasionally eat pieces of wholesome, natural fruit.

There, I’ve admitted it. I can no longer live the lie that I only eat junk-food. Of course, to maintain some appearance of having a normal mainstream type of diet, I at least tend to go for the pre-cut fruit mixtures – I’ve got way too much going on to have time to prepare cut fruit salad from scratch.

Anyway, a few weeks ago I had a platter of these, still sealed in their plastic container, and didn’t get around to eating them in time. About a week after it had expired, when I went to throw it away, I saw a few little white lumps growing all over the pieces of fruit. Non-fuzzy, so I expected they were bacterial rather than fungal. Of course, there’s only one thing I could think when I saw that.

“Oh, wow! It looks like there were only about 5-8 bacterial CELLS on each piece of fruit when I got them! Those things were really CLEAN!”

(Of course, once you can SEE the colonies growing, there are a lot more than a few cells there. Each visible colony’s probably got millions of the little buggers, but each colony starts as a single cell.)

This was, of course, followed by me lamenting that I didn’t have some culture supplies and a microscope of my own to examine them with. Sigh. Anybody out there have any extra microbiology equipment you’d like to donate to a good cause?

So, what’s next? Should I try to start a series of bacterial taxonomy posts? Searches for “what’s a gram-positive?” and “what’s a gram-negative?” sorts of questions seem to be popular ways to reach this blog…

He also enjoys exploring the Big Room (the one with the really high blue ceiling and big light that tracks from one side to the other every day) and looking at its contents from unusual mental angles.
