The exo-enzymes makes the chlorine compounds in the bleach inert which then the fungi uses it as a food source. So when we put bleach on mould we are actually feeding it. Visually it looks like the mould is disappearing because bleach “bleaches” which means it strips the melanin compounds out of the hyphal membrane (just like the melanin in our skin when we get a sun tan). Three weeks later the fungi hyphae recovers the melanin content and the mould becomes visible again so it was actually never gone.

I thought you were making that up Bear, but you'd have to be pretty lucky to get past Mark's anti-cheat software...busted
