Hello all,

Recently we have been having more issues with bubbles in our agar plates. I have extended the "rest" time after adding CaCl2 and dextrose to allow any foam from swirling to dissipate, but still getting bubbles in my plates.

Is there an additive that works with PYCa and M. foliorum that is anti-foam or anti-bubble? Do any of you use it or have you?
