AVALIAÇÃO DO POTENCIAL BIORREMEDIADOR DOS FUNGOS CANDIDA spp. E TRICHOPHYTON spp. NO TRATAMENTO DE LIXIVIADO PROVENIENTE DE ATERRO SANITÁRIO

Abstract

This study compares the efficiency in reducing the toxicity of leachate from a landfill after the application of mycoremediation processes using Candida spp. and Trichophyton spp. fungi through bioassays with Allium cepa seeds. Experimental units were set up for leachate treatment with varying concentrations, inoculated with the selected fungi, and incubated. After incubation, bioassays were conducted using the liquid extract to inoculate ten Allium cepa seeds on Petri dishes. Subsequently, macroscopic analysis indices were calculated. The results revealed that Candida spp. yeast showed superior toxicity reduction results in all experimental units. In conclusion, among the analyzed genera, Candida spp. yeast demonstrates greater efficiency and holds promise for reducing the toxicity of landfill leachate.
