Summary
A fluorescent dye (8-anilino-1-naphthalene-sulphonic acid), which gives no fluorescence, or only a weak one, when added to submerged grown mycelium of the hymenomycete Boletus variegatus, is found to result in a marked increase of fluorescence if the organism is treated with fatty acids. The increased fluorescence is dependent on the presence of undissociated acid molecules as well as on the chain length of the acid. The effect is not due to the acidic character of the molecules, but is highly dependent on lipophilic properties of the substances. Consequently, the fatty acids introduce changes in the characteristics of the cytoplasmic membrane probably as a result of interactions with lipophilic parts of the membrane. The paper finally discusses the contribution of the present results to the elucidation of the influence mechanism of fatty acids in regard to leaking and respiration
