9-aminoacridine fluorescence in the preparative suspensions of Aspergillus and Penicillium fungi

There are given results of pilot studies of 9-aminoacridinefluorescence in the water suspensions containing the dispersed mycelium and spores of fungi-biodestructors of the genera Aspergillus and Penicillium in the article. It is shown that in addition to the quenching of fluorescence typically occurring for amino derivatives of acridine in the main maximum (460 nm for a 9-aminoacridine) the emergence of long-wave fluorescence takes place (about 700 nm). The model scheme explaining generation of long-wave fluorescence as result of dimerization of dye molecules on a polysaccharide matrix of fungi mycelium is offered. It is offered to use measurement of long-wave fluorescence level as control method of fungi development on the various materials.
