Contamination? White specks.
    #26708918 - 05/31/20 11:10 AM (3 years, 7 months ago)

Hey Guys,
    Thought I would ask the community to see if anyone else has seen something like this..
I inoculated this WBS with clean agar from an LC.  After I shook the jar, after about 30% colonization, I noticed these white specks.  I'm not sure if it's mycelium, mold, or if it's even organic.  Maybe gypsum or sand or something else?  Has anyone seen anything like this before?





All input is welcome and appreciated. :smile: Thanks for taking a look.

A difficult one, the specs are not mycelium that I'm sure of. Whether it's some busted grain guts, or gypsum I'm not sure.
If it is a contaminant it looks most like a yeast contamination. What I would do is update this thread tomorrow with more photos,
then one or two more days, if we see any growth we'll know what it is, if they just remain static, it's probably nothing harmful.

That is probably yeast contam.  When you are ready, open them and give them a smell.  You'll know if something is off.  Are the white dots on the grains or the glass?

Yeah yeast or bacteria. See how above the spawn the glass is all grimey.

The white dots are on both the grains and the glass.  Thanks for the input, both of you.
