As the paramecium stuffs itself with a meal of pigmented yeast, vacuoles form. As food particles are digested by acidic enzymes, the congo red will reveal the pH drop-color will shift from a more alkaline red, to a more acidic blue. “They Pulled My Jazz soundtrack!” : (
omgod your hurting that poor thing!!
Perfect music to go with a great video!
OMG this bacterial cruelty!!!1
Poor thing is getting zerg-rushed.
@welcomeToUrMooseyFat you can add Glycerol to the water it will make it thicker.
love the music ^_^ how did you get the paramecium to stay like it did? i have only found one that did that for me!
Is it bad to eat pure yeast?
@wxfix thank you!! that’s it! rotifers!
Sounds like you have some Rotifers. They tooo are fun to watch.
i got some Chaos (Pelomyxa) carolinensis from Carolina Bio supply— i’ve seen paramecium in the culture, but there are these other long things about the size of paramecium, that sometimes suck up food, and sometimes open their heads into too circular ‘weapons’ with super fast rotating cilia (like chainsaws) that whip food into their mouth—-
what are these things???
I use a disposable plastic pipette. You could try one of those “booger bulbs” folks use on babies to suck up your protists and put a drop or two on your slide.
1) I made sure i had a happy bunch of paramecium.
2) I put 1/2 envelope (1tsp or so) of regular bread yeast in 100ml warm water. Then I let it sit somewhere near 37C for a couple hours, till I saw a lot of bubbles in the center of the glass.
3) I added about a dozen or so drops of 1% congo red dye into the glass.
4)Meanwhile, I took a sampling of paramecium onto a depression slide. I waited a couple hours before I applied the congo red yeast.
5) Because it was cold, I didn’t have to.
can you tell me how you prepared the yeast stained with congo red… also,, did you apply something that made the paramecium move slower???
Micro Kombat!
Thank you so much for posting this. We did a lab in biology and I didn’t quite get to this part.
Is there any way to “pick up” and move these microorganisms? I’ve tried to do it several times and ended up just moving them a bit to the side or squashing them.
lmao its so cute haha
yes, they can move extremely fast
yeah in lab we slow them down with a viscous substance called detain.
wow really interesting. Thanks
Yes. This video was shot in real time. This is not a compiled animation. In fact, Sometimes the paramecium move even faster than this.
