Pan Cyan agar (weza), transparent halo around mycelium — bacteria or normal?
​
The mycelium grows white with no obvious mold contamination, but growth is slow and there’s always a transparent/wet-looking halo around the mycelium. The strange thing is the halo only appears around the growing mycelium and doesn’t spread across the plate by itself.
I took transfers from the clean edge, but the same thing appeared again on the new plates (second pic, day 3).
So now I’m confused:
is this bacterial contamination hitchhiking with the mycelium?
should I keep transferring on agar or move to grain?
can cultures like this still fruit normally?
First pic = original spore plate
Second pic = transfer plate
