Organism liking citric acid

[smollerthings]

Hi All,

A couple of days ago, I threw a bunch of used slides into some water and citric acid, thinking the acid would help dissolve mineral deposits while sterilizing everything. I was so wrong. A couple of days later, a white cloud developed in the acidic environment. Anyone knows what this is? Some kind of fungus that has a tropism for acidic environments?

Oh my, isn't that interesting. So what I had could possibly be aspergilus niger from the citric acid, rehydrated and feeding on the remaining sugar in the powder...
