    Decolorization of Orange G and Remazol Briliant Blue R by the white rot funfus Dichomitus squalens: Toxicological evaluation and morphological study

  • Original language description

    Dichomitus squalens efficiently decolorized both Orange G and Remazol Brilliant Blue R (RBBR) in static and shaken culture and also on solid medium within 14 d. The presence of the dyes in the culture medium mostly caused a decrease in biomass productionand in growth rate, which was more significant in the case of RBBR. After 14 d of cultivation, electron microscopy showed substantial morphological changes in mycelia of D. squalens growing in media containing dyes. The hyphae deformations were more intensively manifested in solid media than in liquid culture. The toxicity of synthetic dyes Orange G and RBBR was tested using a bioassay based on the growth inhibition of duckweed Lemna minor. The results showed higher toxicity of RBBR than that of OrangeG. The toxicity of both dyes decreased after the decolorization process

    Dekolorizace Orange G a Remazol Brilliant Blue R houbou bílé hniloby Dichomitus squalens: toxikologické hodnocení a morfologická studie

  • Czech description

    Dichomitus squalens dekolorizuje účinně Orange G i Remazol Brilliant Blue R (RBBR) ve statické i třepané kultuře a také na pevném médiu během 14 dní. Přítomnost barviv v kultivačním médiu snižuje tvorbu biomasy a růstovou rychlost, výrazněji u RBBR. Elektronová mikroskopie odhalila výrazné morfologické změny mycelia houby rostoucí v přítomnosti barviv. Deformace hyf se projevují výrazněji na pevných médiích. Testy toxicity, založené na inhibici růstu okřehku Lemna minor, ukázaly vyšší toxicitu RBBR. Toxicita obou barviv poklesla v průběhu dekolorizace
