Colourful Paramecium

Post by Gerd »


This is a picture of my microscopic pets, paramecium caudatum, fed with dyed yeast cells.
I used Congo red for dying the yeast, because Congo red is an indicator for pH too :
red with pH above 5.2, blue below pH 3. First the ingested yeast cells are colourful red in the feeding vacuoles,
later they turn to blue, a wonderful and easy to do experiment.
Thanks for looking,

Beautiful picture - I must try feeding some like this...

Though we lean upon the same balustrade, the colours of the mountain are different.
