Sažetak
The market for medicinal mushrooms is steadily increasing as they are a source of valuable biologically active compounds, which are extracted from the fruiting bodies and mycelial biomass of the mushrooms using suitable solvents. After extraction, the inactive extracted fungal biomass remains in the form of a filter cake that has not yet been properly valorised. Promoting the use of by- products and waste materials as a resource is one of the basic ideas of the circular economy model that has been implemented in the development strategies of many countries. The potential of microbial biomass, both living and inactive, as adsorbents (biosorbents) for the removal of a variety of pollutants (e.g., heavy metals, synthetic dyes, pharmaceuticals, etc.) has been intensively studied. The objective of this study was to investigate the biosorption potential of the extracted inactive biomass of the medicinal mushroom Fomitopsis pinicola for the removal of the synthetic dye Congo red (CR) from a model dye solution. The effect of various factors affecting the adsorption process was studied in a batch procedure, namely the concentration of biosorbent (0.4 - 10 g/L), contact time (5 - 360 min), initial CR concentration (10 - 150 mg/L), pH (4 - 10), and temperature (15 - 35 C). The obtained data were analyzed using adsorption equilibrium models (Freundlich and Langmuir) and kinetic models (pseudo-first order model and pseudo second order model). The percentage of CR removal increased with increasing biosorbent concentration and contact time between biosorbent and CR. Increasing the initial CR concentration resulted in a decrease in the percentage of its removal, but also increased the adsorption capacity. The biosorption efficiency was highest at pH=4. Analysis of the experimentally obtained data using equilibrium and kinetic adsorption models revealed that the Freundlich model and the pseudo-second- order model better described the process of CR biosorption on inactive F. pinicola biomass. The results suggest that the extracted inactive biomass of the medicinal mushroom F. pinicola has potential for remediation of wastewater contaminated with synthetic dyes.
