Store in the fridge if you must but be very careful not to approach
freezing temperatures.  It will solidify an separate very quickly
destroying it's useability.

As a bookbinder I found that a few drops of 5% thymol tincture
applied to a small piece of cotton wool fastened to the inside of
the lid of the container controlled most fungus in pva, eva and even
starch paste.  But the main thing is to never dip a brush in supply
jar, always pour a small quality into a small working jar and then
get the lid back on quickly on the supply container.
