Rotten Part of the Carrot

https://www.youtube.com/watch?v=gaOdCLEErHs When I took a carrot out of the fridge, a part of it was blackened and hollowed out. I wanted to take a look at it under the microscope. It is one of those places where chaos and confusion replaces order. Those places are very interesting to me. Join the t...

The Rotten Place on a Carrot

I examined the place on the top of a carrot that was hollowed out and rotten. I am not a biologist so I can never tell if I am really seeing what I should be seeing, but I took pictures of what I thought was significant. The light was very poor and the pictures very grainy, but I was able to show ho...

https://www.youtube.com/watch?v=SZDiEaQDGu4

I offer a collection of neat microbe pictures.
A walking ciliate, a testate amoeba (probably), magic disappearing ciliates,
a complete rotifer portrait, and great fancy ciliate
that looks like a microscopic cruise ship. Step right up!

Over and Under

https://www.youtube.com/watch?v=yjMBFFv64Cs
A 3-D view of the biofilm,
focusing up and down to try to see
the microbes pushing around in it,
under it, and above it.
Photographing life in the biofilm
is like photographing in a deep fog.

How much does the desiccation of onions to make dried onion seasoning
actually destroy the cell structure of the onion? I've always wanted to know.

The Variety Biome in my Artificial Puddle

The little bubble thing covered with long cilia goes racing around then stops where it left from. The tulip-shaped vorticella-relative zips itself closed then slowly resumes its endless stirring---drawing tiny things into its mouth. The spooky amoeba wends it way to and fro. Little balls of nervousn...

Re: Amoebas dangerous ?

When you look at plants, especially those in moist environments, you are bound to find amoebas. There was a You Tube by a dentist looking at biofilm (plaque) in the mouth of a patient who found two amoebas crawling among the bacteria and consuming them. The dentist did warn us that we don't want to ...

Intricate Flower

https://www.youtube.com/watch?v=rB6NGD5qZqE
When nature granted me a fallen flower,
I dissected it brutally and pressed it on a microscope slide
--squeezing much of the color out if it in the process.
But the intricacies on the flower surface are sources of wonder.

Algae Bloom in Salt Water Sample

A white film started forming on the salt water sample donated by my granddaughter's salt water fish tank. It appears to be a plume of algae spores.

Microbe Countryside

Out away from the biofilm, the metropolis of the bacteria,
protozoans live a quieter life. The only thing they have
to worry about (and I'm sure they do worry) is each other.

Effect of Biofilm on Protozoans

All my observations show that protozoans tend to get trapped and immobilized by bacterial biofilms. Research that I found shows that protozoan predation reduces biofilm production. It's the protozoans who are dominant. Why am I getting the wrong impression?
