agar discolorization
    #26746784 - 06/15/20 02:57 PM (3 years, 7 months ago)

I'm new to agar, I squirted 2 drops from a MS syringe onto agar into sterilized 1/2 pint jars on 5/27/20. The top surface of the mycel. is very white, but the area between the mycel. and agar has a light brown layer. Is this contam.? The two pics here are of the same jar. Thanks for any help. Sorry if this question has already been asked.

I hate to ask again, 5 days from last post the mycel. is very white on top and from the bottom of the jar the blue tinted agar is turning tan.  Is it time to dump it? Or, are they good? Here are 2 pics of the same jar. Thanks for any input.

As stated before, mycelium eats food colouring readily.

You should definitely do some transfers of that mycelium.
