Navy Blue Contamination
    #4073049 - 04/19/05 04:17 PM (11 years, 7 months ago)

I inoculated a rice/vermiculite cake with an isolated strain of mycelium selected from an agar plate. Within 4 days I had three navy blue patches, but no other growth. I now have a cake that is half fluffy white mycelium and half navy blue. These two organisms appear to be discreet. The mycelium side is now fruiting. I have not found any record of a type of contamination that matches this navy blue growth, what could it be? And should I destroy the cake?

I had the same thing, its green\blue mold. I thought it was navy bluish, and it dident look like any of the pictures. I took it out and grew it on the side, sure enough it was mold.

Peace

Most likely Penicillium. . .it can range from blue-ish to green.  I can't think of any other possible navy blue contams, but that doesn't mean there aren't any.  It doesn't seem like you can do anything but kill the jars :frown:
