Fungal biomineralization potential for stabilization of waste powders

Original language description

This study investigates the potential of the fungus Trichoderma reesei DSM 768 for biologically-induced calcite precipitation, focusing on consolidating fine-grained waste concrete fines. While microbially-induced calcite precipitation is extensively studied, fungal biomineralization remains largely unexplored, particularly regarding the influence of Ca2+ sources and pH adjustments on crystal morphology and mineral composition. Fungal biomineralization outcomes using calcium chloride and calcium lactate were compared with and without pH adjustment. Scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, and thermogravimetric analysis revealed distinct CaCO3 morphologies and phases, notably calcite and vaterite. Samples treated with T. reesei predominantly formed densely packed calcite crystals, with variations influenced by Ca2+ source and pH. Bacterial positive controls employing Sutcliffiella cohnii DSM 6307 produced distinct rounded vaterite crystals. Fungal biomineralization led to finer, more homogeneous crystal distributions, highlighting its potential for sustainable stabilization of waste materials.
