Oxalate Crystallization under the Action of Brown Rot Fungi
Brown rot fungi belong to the wood-rotting fungi, which produce oxalic acid and actively decompose wood. We first found oxalates formed under the action of brown rot fungi in natural conditions on stone (Rogoselga adit, Karelia, Russia), proposed a model for their formation, and confirmed the hypoth...

Brown rot fungi belong to the wood-rotting fungi, which produce oxalic acid and actively decompose wood.

We synthesized under the action of four species of brown-rot fungi (Serpula himantioides, Serpula lacrymans, Coniophora puteana, Antrodia xantha) on different mineral substrates analogs of all known biofilm oxalate minerals and oxalates of such toxic heavy metals as Pb, Cu, Mn.
