Mycelium biocomposites (MBCs) are sustainable materials that bind organic waste particles to create solid biocomposites, yet applications of these materials are constrained by their inferior structural strength relative to traditional architectural materials. This research investigated the optimal conditions for fungal growth and microbial calcium carbonate precipitation (MICP) for mineralising matrices of MBCs, with the aim of enhancing MBC properties. <\/p>\n\n\n\n

Three ureolytic fungal strains, i.e.,\u00a0Trichoderma reesei<\/em>,\u00a0Neurospora crassa<\/em>, and\u00a0Penicillium chrysogenum<\/em>, were tested for their ability to facilitate biomineralisation. A range of calcium and urea concentrations were applied to each strain to assess their influence on growth dynamics and ability to precipitate calcium carbonate through urea hydrolysis. The growth rates, induced pH change, biomass production, and calcium uptake efficiency to form calcium carbonate were measured. <\/p>\n\n\n

The results showed that each fungal strain responded differently to calcium and urea, impacting growth rates, biomass production, and calcium carbonate precipitation. Notably,\u00a0T. reesei<\/em>\u00a0achieved 87% calcium removal when urea concentration was three times than calcium, whereas\u00a0P. chrysogenum<\/em>\u00a0removed 97% of calcium with five times more urea than calcium in the environment. This research provides insights into ureolytic fungal strains that are appropriate for biomineralisation under suitable conditions, to increase the applicability of MBC properties for design and engineering applications using MICP.<\/p>\n\n\n\n
