“…Due to the foregoing, bioremediation through microorganisms is an environmentallyfriendly, efficient and even, profitable alternative. The valuable potential of various fungi, bacteria, and algae species for the removal of dyes have been reported (Cao et al, 2019;Martínez-Berra et al, 2018;Grandes-Blanco et al, 2013). Fungi present advantages over other organisms to this end, one of which is their oxidative mechanism, which avoids the formation of more toxic compounds, such as the anilines formed in bacteria-based dye reduction processes (Pointing, 2001).…”

The environment pollution or contamination is a serious problem, a great deal of research is being undertaken to combat contaminants such as xenobiotic and recalcitrant compounds, particularly heavy metals, dyes,phenolic compounds and other recalcitrant pollutants produced by a wide range of industrial activities. These compounds have an adverse impact on the environment, particularly when generated by industrial processes and then disposed off without adequate treatment. Mycoremediation is defined as the use of fungi for bioremediation, especially degradation or retention of contaminants. Biosorption and bioaccumulation are two of the mechanisms by which fungi remove contaminants through mycelium. In many cases, these processes involve metabolization and even mineralization of these contaminants, corresponding to a biological contaminant removal system with great potential for use in bioremediation processes. The present review describes the unique characteristics of fungal mycelium that make it a biomaterial with potential applications in various fields of biotechnology, specifically evaluating its biosorption/bioaccumulation properties and potential application for the bioremediation of different water-borne contaminants. This review focus on the researches conducted on the bioremediation of inorganic and organic pollutants, the mechanisms involved in the process, and the main environmental factors affecting it. Moreover, kinetics and equilibrium modeling of the removal efficiency achieved via biosorption/bioaccumulation is analyzed in order to better understand these processes and overcome some of the technical barriers to their large-scale application in the mycoremediation of wastewater. Key words: Bioaccumulation, Biosorption, Fungi, Mycoremediation, Xenobiotics

“…Por tal motivo, se reportan concentraciones de colorantes de 100-500 mg/L en las aguas residuales (Isik, 2004). La gran mayoría (60-70%) de los colorantes utilizados en la industria textil son colorantes azo, cuya característica principal es el enlace insaturado de dos moléculas de nitrógeno (enlace azo, N=N) que unen estructuras aromáticas sustituidas (Van Der Zee & Cervantes, 2009;Martínez et al, 2018). Los colorantes azo son contaminantes electrofílicos, lo que los hace difíciles de ser tratados efectivamente por procesos aerobios convencionales, pero son factibles de someterse a procesos de biotransformación reductiva bajo condiciones anaerobias (Brown & Laboureur,1983;Pagga & Brown, 1986).…”

Azo dyes are susceptible to be treated by reductive biotransformation process under anaerobic conditions. The process can be accelerated by the addition of quinones and humic substances acting as redox mediators (RM). In this study, the anthraquinone-2-sulfonate (AQS) was immobilized on granular activated carbon (GAC) to evaluate the reductive biotransformation of congo red (CR) in an up-flow anaerobic sludge blanket reactor (UASB). The syudy was divided in five stages, where the reactors with immobilized RM and without RM were operated under different salinity levels (1% and 3%) and hydraulic retention times (HRT = 5 and 10 h). The reactor with immobilized RM (GAC-AQS) achieved a decolorization efficiency of 96.1% and substrate consumption of 98.8% with a HRT = 15 h and 1% of salinity. Nonetheless, with a salinity of 3% and the same HRT, the efficiency was similar (95.6%). The reactor provided with unmodified GAC achieved values below those observed in the reactor GAC-AQS, with decolorization efficiencies of 90.8% and 75.8%, and substrate consumption of 97.1% and 88.4%, for the stages IV and V, respectively. The microbial consortium sued was able to promote the biotransformation of azo dye and no inhibitory effects were identified.
