Limestone, a compound with a molecular formula of CaCO3, is naturally found in organic and inorganic materials such as sediments, seashells and eggshell. High concentrations of calcium carbonate may cause detrimental effects on living organisms owing to antacid property of CaCO3. Moreover, high amount of CaCO3in magnesite ores, an important material with economic value, obstructs processing of the ore and its removal increases the processing prices. Though hazardous potentials of high concentrations of calcium carbonate, it has an industrial importance. It is used in pharmaceutical industry, production of various
materials such as marbles, limestones, chalks, paints and PVC. It is also used in medicine to balance phosphate derivatives in blood. In the present study, determination of potential of CaCO3 recycling from polluted magnesite ores of fungal isolate SZN22, which is isolated from Afşin-Elbistan lignite mine and metabolizes calcium derived compounds, and bringing in this knowledge to the industry was aimed. For this aim, the magnesite samples were treated with SZN22 under controlled conditions.Then CaCO3solving potential of the fungal isolate was assessed. After its activity was proven, it is identified and characterized
by using conventional and molecular techniques. According to the results, it is identified as Penicillium sp. In conclusion, it is revealed that the fungal isolate Penicillium sp. SZN22 can solve CaCO3derivatives in polluted magnesite ores and it can be used for development of new CaCO3 recycling technologies.
