Decolorization of Textile Reactive Dyes and Effluents by Biofilms of Trametes polyzona LMB-TM5 and Ceriporia sp. LMB-TM1 Isolated from the Peruvian Rainforest

Abstract

The textile industry creates environmental problems due to the release of highly polluting effluents containing substances from different stages of dyeing that are resistant to light, water, and various chemicals, and most of them are difficult to decolorize because of its synthetic origin. The biological degradation of dyes is an economical and environmentally friendly alternative. The aim of this work was to use biofilms of basidiomycete fungi isolated from the Peruvian rainforest for the decolorization of synthetic reactive dyes, considering the advantages of these systems which include better contact with the surrounding medium, resistance to chemical and physical stress, and higher metabolic activity. Among several isolates, two were selected for their capacity of rapid decolorization of several dyes and their biofilm-forming ability. These strains were molecularly identified as Trametes polyzona LMB-TM5 and Ceriporia sp. LMB-TM1 and used in biofilm cultivation for the decolorization of six reactive dyes and textile effluents. Azo dyes were moderately decolorized by both strains, but Remazol Brilliant Blue R (anthraquinone) and Synozol Turquoise Blue HF-G (phthalocyanine) were highly decolorized (97 and 80 %, respectively) by T. polyzona LMB-TM5. Degradation products were found by HPLC analysis. Simulated effluents made of a mixture of six dyes were moderately decolorized by both strains, but a real textile effluent was highly (93 %) decolorized by T. polyzona LMB-TM5. In summary, T. polyzona LMB-TM5 was more efficient than Ceriporia sp. LMB-TM1 for the decolorization of textile dyes and effluents at high initial rates enabling the development of in-plant continuous biofilm processes.

Biodegradation of anthraquinone based dye using an isolated strain Staphylococcus hominis subsp. hominis DSM 20328

“…The colored wastewater is aesthetically unacceptable and toxic to human and aquatic life. Dyes are difficult to decolorize due to their synthetic origin, complex structure, and recalcitrant nature [2,3]. These factors make it mandatory to remove/degrade dyes from textile wastewater before being disposed off into water bodies.…”

Assessing the Fungal Simultaneous Removal Efficiency of Carbamazepine, Diclofenac and Ibuprofen in Aquatic Environment

“…In addition, there are several reports that show members of the phyla Ascomycota and Zygomycota as producers of ligninolytic enzymes, and no report is available on the simultaneous biodegradation of CBZ, DCF, and IBP. Most of the reports on these fungi including T. polyzona are focused on their capability to decolorize recalcitrant dyes ( Fu and Viraraghavan, 2003 ; Cobas et al, 2013 ; Cerrón et al, 2015 ). The degradation of DCF alone was conducted using A. niger ( Aracagök et al, 2018 ).…”

Bioprospecting three newly isolated white-rot fungi from Berbak-Sembilang National Park, Indonesia for biodecolorization of anthraquinone and azo dyes

“…The BRB 81 also showed a higher decolorization of RBBR dye (51%) compared to other Ceriporia sp. which had less than 40% removal within 96 h (Cerrón et al 2015). In terms of AO7, which was known to be more difficult to be degraded, BRB11 could remove up to 37% that was higher than the removal by T. versicolor around 25-30% within 3 days (Yang et al 2017) and other basidiomycetes fungi such as C. versicolor, Pholiota sp., and Pleurotus sp.which showed less than 20% removal (Nozaki et al 2008).…”
