I was looking at a colony of Euglena using a light microscope and then I applied a drop of detergent to the slide and noticed that they started moving backwards + they stopped using their flagellum to move and instead moved like earthworms. Anyone have any ideas as to why?

They're dying

Are they still doing that or did they just fade out into a motionless state? I am actually intrested.

The solution might disable their ability to use flagellum, other than that I don't fucking know they might be dying.

Maybe if energy sources are scarce?
I can believe it pulls some effort to keep their flagullum spinning.

OP here, phone was dead. I don't actually know. I was observing them for about 45 minutes and could not find any motionless cells.

Very true. However, the Euglena on the slide were swimming around in a medium so I don't think that's it

>detergent
Detergent is a xenoestrogen. Thats all i know.
Lol maybe flagella work on testosterone.

Is it possible for the detergent to cause lysis? Aka breaking down the celll membrane
>>
What's in the detergent. That's like the first piece of information you should provide us. Detergent is like.. the broadest of terms to describe detergent.

Microbio is such boring shit.
I'm a biochem major. When do I get into cool stuff like metabolic pathways of chemicals in the body and gene splicing?

I don't have a bottle available right now. It's a washing-up liquid, and Fairy is the brand.

Metabolic pathways like glycolysis, krebs cycle, DNA synthesis, amino acid metabolism should all be handled in a classic biochem course.
Gene splicing (are you kidding) is part of courses handling DNA and genetics and some molecular biology. It's basic knowledge that'll be used throughout your biochem career.
Like, I got info about both your topics of interes in a course about molecular biology of plants for example.
But I also got the same thing when I learned about the biodiversity of micro organisms.

Looking it up it states:
LISTED INGREDIENTS
15-30% Anionic surfactants, 5-15% Nonionic
surfactants, Perfume, Geraniol, Limonene
Anionic surfactants could interfere with the protons or other kations by disrupting the establishment of the PMF (or other mechanism) needed to drive the flagella is my best guess

I see. Thanks for the input, it's much appreciated.

Pretty impressive that they had a backup locomotive action.
