This AM Holly was cleaning out the fridge and found this nice jar of applesauce:

Right away it was spirited to the Greenspan analytical laboratory for inspection. I have a microscope  built from a box of broken microscopes purchased from Edmund Scientific a few years back. It needed a little custom machining and parts, but it works; its highest power is 400X. I bought microscopy stains and various other materials on-line.

I figured that the pink stuff would be bacteria, but the gray/flesh-colored body would be fungus. Since the gray/flesh thing was spongy, I thought I’d find mycelia - the filaments that make up the body of a multicellular fungus.  I was right!

I made some slides with methylene blue, and here is one that shows both organisms.  The little round/lozenge-shaped things are bacteria and yeast.  I don’t know what kind of bacteria yet. The filaments are the mycelia of the “black thing.” you can see some interior structure within the mycelium in the center.

I will have to continue working on the image quality; I think i can do better if I can find more time to play with it.
