Abstract

Effects of Cd on growth and glucose utilisation of Paxillus involutus, Rhizopogon subcaerulescens and Suillus bovinus were investigated in vitro in liquid culture. S. bovinus was the species most sensitive to Cd in terms of dry matter production and P. involutus was less sensitive than R. subcaerulescens. Greater production of hyphae of P. involutus than the other fungi appeared to confer some degree of Cd resistance, possibly by binding Cd onto cell walls. Growth of the three fungi was increased by glucose addition. While Cd significantly reduced dry matter production of the fungi, there were no significant differences in glucose consumption caused by Cd treatment. This suggests that the use of glucose might have been diverted to detoxification and/or repair mechanisms. Further studies on respiration rates and energy metabolites of these fungi under Cd exposure are needed in order to clarify the results of the present study.
