✦ Synopsis

The influence of AP + on the membrane fluidity of the mycorrhizal fungus Lactarius piperatus (L.ex.Fr.) S. F. Gray was studied. When mycelia grew on media supplemented with 1 or 10 mM aluminum for 21 days, a significant increase in fluidity was detected, compared with the corresponding controls. The comparisons of the EPR spectra calculated by a model, with the experimental ones showed that the spectra are superimpositions of two components with different membrane ordering. The action of aluminum induced a relative enlargement of the less immobilized portion in the membrane. No significant alterations of fluidity were measured after 30-minute treatment, with AP +.
