Abstract:

The investigations on calcium enrichment in mycelia of three species of edible fungi: Pleurotus nebrodensis, Pleurotus eryngii and Pleurotus citrinopileatus Sing subjected to plate culture were conducted using calcium chloride as the calcium source. Results indicated that different fungus species, carbon sources and Ca2+ concentrations had a significant effect on the enrichment of calcium. In the same culture medium, the highest calcium enrichment in Pleurotus nebrodensis was observed. In addition, when calcium enrichment in three fungi was investigated in culture media with different carbon sources, the calcium enrichment from high to low revealed an order of lactose, maltose and sucrose. The highest calcium concentration of Pleurotus nebrodensis was obtained in the medium with lactose as the carbon source and 0.6% calcium.
