| Abstract | The optical fluorescence properties of whole Antarctic fungal spores have been investigated in order to evaluate the effects of artificial enhanced UV irradiation. The spores suspension show three main emission bands with maxima around 345, 430, and 510 nm, undergoing to substantial changes after irradiations at λ > 280 (UV - B + UV - A + and λ > 265 (UV - C + UV-B + UV - A + visible). The optical spectroscopic analysis, conducted also on total sporal extracts, indicates the involvement of the electron-proton translocating molecules in the respiratory chain and of the carotenoid pigments in these changes. Moreover it seems that the UV irradiation is responsible for the accumulation of age pigments in the irradiated spores. |
