• Resumen

  • Geochemical variations induced by the interaction of fungus and calcite were studied. The results showed that the fungal metabolic activities could accelerate the calcite dissolution rate, and dissolution continued even when the solution was supersaturated with respect to calcite. The calcite dissolution rate was also influenced by solution chemistry, such as pH and the concentration of HCO-3. Based on these results, the importance of fungal activity in the formation of karst geomorphology was discussed.
