This is interesting, I hadn't seen this paper before. I've had a citric acid allergy (both natural and mold-produced) most of my adult life, but it really seemed to kick into high gear after I spent an extended period of time living somewhere with severe mold problems. Since some people in this thread seem to be unaware of the black mold/citric acid relationship entirely, I'll further clarify that aspergillus niger, the citric-acid-producing "black mold" on rotting fruit, is not the "black mold" associated with wet drywall. (The place I was staying had both...) Since it's only a single anecdote, and I'm not an immunologist, I've had no way to reason about whether these could be connected. Good to see at least someone is studying it in some cursory way.
