Abstract

Based on the experimental research on determining the role of functional groups of the cell wall in the microfungus Penicillium canescens in the process of Pd(II) biogenic precipitation, it is revealed that hydroxyl and, to a lesser degree, amine groups participate in the sorption process in a weakly acidic medium (рН ~ 6), which is the most typical for natural conditions. The role of carboxyl groups under these conditions is not clear. The results obtained are of certain interest for understanding the mechanisms of platinoid mineral formation in organogenic sequences.
