The aim of this work was to study the degradation and detoxification of three textile azo dyes (Reactive Red 198, Reactive Red 141 and Reactive Blue 214) by mixed fungal cultures from semi-arid region of Brazilian Northeast. Sediment samples of twenty water reservoirs in the surroundings of Serra da Capivara National Park, area of environmental preservation in the caatinga in the State of Piauí, with semi-arid climate, were evaluated in order to select the consortia of fungi capable to degrade and detoxify these dyes. The mixed fungal culture from Caldeirão Escuridão (CE) reservoir was the most efficient in the degradation and detoxification of the dyes tested. |

ABSTRACT: The objective of this research was to evaluate the efficiency of artificial dyes, sunset yellow and red bordeaux S, and the use of glycerol in different concentrations to consistently stain fungal structures in slides containing spores of Oidium sp., Albugo ipomoeae-panduratae, Pochonia chlamydosporia and hyphae of Phytopythium helicoides. Commercial product mixtures of the artificial dyes at 0.5, 1.0, 1.5, 2.0, 3.0 and 5.0% (w/v) added with glycerol at 0.25, 0.5 and 1.0% were evaluated. To stain chlamydospores, the suspension was placed in the staining solution or heated at 80ºC for 5 minutes. The slides were prepared by the wet mount slide method. Fungal spores were consistently stained starting at a concentration of 2% of the staining... |
