title: Rylux BSU stimulates spore germination in Trichophyton mentagrophytes and Aspergillus fumigatus and increases the survival rate after UV-irradiation.
abstract: Calcofluor-allied optical brightener Rylux BSU stimulated spore germination rate in Trichophyton mentagrophytes and Aspergillus fumigatus both if supplemented into Sabouraud glucose agar and if used for pretreatment of spore suspension prior to inoculation at low concentrations. Maximum stimulation of germination was obtained if 0.2% Rylux BSU was used for pretreatment in aqueous solution for 1 d prior to inoculation (130% in T. mentagrophytes and 150% in A. fumigatus, respectively). Pretreatment with 1% Rylux BSU provided strong protection against UV-irradiation and resulted in increased yields of cultural variants after UV-irradiation.
