ABSTRACT White-rot fungi are considered to be promising biotechnological tools to complement or replace the current technologies for the treatment of effluents from textile production plants. The aim of this work was to investigate the decolorization capacity of Ganoderma weberianum B-18 in solid state fermentation with sugarcane bagasse as a substrate and ligninolytic inducer as well as to decolorize and detoxify industrial effluents by this strain in a laboratory scale packed-bed bio-reactor. The results demonstrated that G. weberianum B-18 indeed showed to possess decolorization capacity in solid state fermentation with sugarcane bagasse supplemented with synthetic dyes. Moreover, fungal biomass of G. weberianum B-18 immobilized in sugarcane bagasse in a packed-bed bioreactor was shown to efficiently decolorize and detoxify different dyes and authentic industrial effluents in semi-continuous conditions. In this decolorization process, laccase enzymes secreted by the fungus played the main role. Hence, a packed-bed reactor with G. weberianum B-18 immobilized in sugarcane bagasse seems to be a suitable system for the further development of an efficient bioprocess for large-scale treatment of dye-containing wastewaters.

固定在实验室规模填充床生物反应器中的灵芝 B-18 对染料和工业废水的生物降解和解毒

摘要 白腐真菌被认为是一种很有前途的生物技术工具，可以补充或替代现有的纺织生产厂废水处理技术。这项工作的目的是研究灵芝 B-18 在以甘蔗渣为底物和木质素分解诱导剂的固态发酵中的脱色能力，并在实验室规模的填充床生物中使用该菌株对工业废水进行脱色和解毒。 -反应堆。结果表明，G. weberianum B-18 在用甘蔗渣补充合成染料的固态发酵中确实显示出具有脱色能力。此外，G. 的真菌生物量。在填充床生物反应器中固定在甘蔗渣中的 weberianum B-18 被证明可以在半连续条件下有效地对不同染料和真正的工业废水进行脱色和解毒。在这个脱色过程中，真菌分泌的漆酶起主要作用。因此，将 G. weberianum B-18 固定在甘蔗渣中的填充床反应器似乎是进一步开发用于大规模处理含染料废水的有效生物工艺的合适系统。
