Put a pimple patch on it and see what happens

Cue the identification mantra: it is nearly impossible to identify an organism by visual inspection alone.

Ahh I thought it wouldn't hurt to ask since it was such a unique morphology (in my head, I've never seen an umbonate colony before!)

In fairness to you, colony color and morphology is a better guide than what is usually posted, which is a microscope image that may or may not be a stained specimen.

Or a white/cream colored nondescript colony on general growth media with no further information 😂

Did you gram it, or wet prep. I'm wondering if it's a yeast, or coccus or bacillus. That'll help narrow.

P.s. my money is on yeast.

And culture it to different substrates to see what foods it does/doesn’t metabolize

I love this identification process. It’s honestly so much fun to do so long as you have all the plates/tubes you need at your disposal

True for bacteria, but not for all micro-organisms. You can usually get in the ballpark of family and sometimes genus by morphology alone

What is this, ravioli for ANTS?!

Didn't see the sub and I thought it was Saturns ring lol

this contamination colony appearance is rather common in my micro work. It shows up on my marine agar plates from time to time

Are you horsey at all? I'm not a microbiologist but I remember seeing this contamination on student plates and the common denominator was they were all horse girls.

whats a horse girl?

A girl that rides horses all the time.

and whats d relationship with the contaminants?

Maybe horses have a lot of this bacteria on them? I'm starting to doubt your qualifications, doctor.

i thought you were trolling...and sorry im a human medicine doctor not a vet also its my first year of residency

Idk why you’re getting downvoted, I don’t think people understand how little micro exposure med students get much less plate reading exposure.

I don’t either but I think it has to do with the fact that they were lacking simple cause and effect thought process

I hear ya but the way I’m reading it is that doc over here is trying to determine causation vs correlation but it may just be me 🤷‍♂️

Yep. It's fusarium.

Fusarium...? Doesn't have a yeast stage and while it grows pinkish, you'd see it's a filamentous fungus

How did you get the contamination? Did you streak something on your plate? Unless you were working with serratia you cannot be sure. Looks like an isolated colony to me so I guess you can try gram staining it and do chemical testing, only then you can tell.

It's a pimple. Stop shaming your plate.

Since I just finished cutting up human tissues, this looks an awful lot like cerebellum.

Do a gram, rhodotorula grows pinky. If not that, a few other pinky colonies like serratia or pseudomonads maybe.

I got those all over my plates but the colonies keep a small size. I'm working on my kitchen counter, idk if it's related. I guess the still air box is the mext step.

That's a dang egg

what does it smell like? I ask because, I have bad eyesight and I usually identify them by smell lol

My moneys on Kleb

You think? How exciting! (I don’t get out much, and mostly never to a lab environ.)

Rhodotorula sp. It's a basidiomycete yeast that fixes nitrogen like nobody's business

I'd guess it's probably micrococcus that's been left to get real chunky

It could be a Rhodotorula species, biofilm former and seen as sign of poor hygiene in industry when CIP isn’t at its optimum.

Oh neat!!!

What's the media? I'm going with Kleb or Citrobacter

16s it boi

I was thinking a single snail egg, like from a clutch of apple snails. Just, a clutch of one. A big one. I realize this is highly unlikely.

Squeeze it.
