“…Fungi inactivation was performed by placing the fungi mycelia in an oven at 50°C for 24 h. After 3 day, due to no enzymatic activity, the color removal was achieved to be about 10% for both the inactive fungi mycelium and fungi free medium in the dye solutions. Similar tests in the same manner were also performed for textile wash water effluent and about 10% color removal by adsorption was observed in a previous study . Results supporting this study were also reported for Coriolus versicolour and P. chrysosporium indicating that enzymatic activity initiated and increased the biodegradation process .…”

“…The results showed that the highest decolorization levels were achieved at pH 4.5 in both AR 88 and RR 180 cultures. The high level of decolorization occurring during the first day was primarily due to adsorption onto the fungus mycelium . Hai et al also pointed out that adsorption occurred in mycelia in the first 24 h and enzymatic activity degraded the dye in the remaining incubation time.…”

White rot fungi have powerful and broad specific extracellular enzymatic systems and can degrade multiple types of recalcitrant compounds including azo dyes, therefore, they are used in the field of bioremediation. In the present study, decolorization and organic matter removal of Acid Red 88 (AR88) and Reactive Red 180 (RR180) dye solutions were performed using the white rot fungus Phanerochaete chrysosporium in a bioreactor. Degradation of the dyes was assessed using a hybrid process consisting of a fungal membrane bioreactor coupled with a photocatalytic membrane reactor. The photocatalytic oxidation step was conducted using the semiconductor ZnO as the catalyst with UVA irradiation. Experimental data with the fungal membrane bioreactor showed that the optimum pH was 4.5 for P. chrysosporium. Integrating photocatalytic step after the fungal membrane process improved the chemical oxygen demand (COD) removal efficiency up to 98 and 96% for RR180 and AR88 dye solutions, respectively. Color removal efficiencies after the photocatalytic degradation were 99.9% for both dye solutions.

“…Protein içeriği açısından tüm boya derişimlerinde benzer salınımları gösterdiğinden boya derişiminin bu fungus için çok etkili olmadığı düşünülebilir. Gerçek atıksu çalışmalarında da benzer şekilde P. chrysosporium verimli sonuçlar vermiştir [19]. Fungal proseslerin kullanıldığı birçok çalışmada renk gideriminin ve KOİ gideriminin bakteriyel proseslere göre daha yüksek olduğu belirlenmiştir.…”

ÖZBu çalışmada fungal biyoreaktörler ile tekstil endüstrisinde yaygın olarak kullanılan boyar madde çözeltilerinin (Reactive Red 180 ve Acid Red 88) biyolojik parçalanması incelenmiştir. Fungal biyolojik prosesin kullanıldığı sistemde 100 mg/L boya konsantrasyonunda, optimum çalışma pH değerleri Phanerochaete chrysosporium için 4,5, Pleotrus ostreatus için 5,0 olarak bulunmuştur. Fungal biyoreaktörde, P. chrysosporium için kimyasal oksijen ihtiyacı gideriminin %94 ve P. ostreatus için ise %98 olduğu ve renk gideriminin ise P. chrysosporium için %98,0 ve P. ostreatus için %99,5 olduğu belirlenmiştir. Anahtar Kelimeler: Biyolojik parçalanma, renk giderimi, Phanerochaete chrysosporium, Pleotrus ostreatus TREATABILITY OF WASTEWATER FROM TEXTILE INDUSTRY IN FUNGAL BIOREACTOR ABSTRACTIn this study, biological degradations of widely used textile dyes, Reactive Red 180 and Acid Red 88, in the fungal bio-reactor were examined. In 100 mg/L dye concentration optimum working pH for Phanerochaete chrysosporium and Pleotrus ostreatus was found as pH 5.0 and 4.5, respectively. During degradation in fungal bioreactor, 94% and 98% of chemical oxygen demand were removed by P. ostreatus and P. chrysosporium, respectively. 98.0% and 99.5% colour removal were achieved by P. chrysosporium and P. ostreatus, respectively.

“…Furthermore, most of the photocatalytic membraner eactors described in the literature combinep hotocatalysis with pressure-driven membrane processes, such as microfiltration, [125][126][127][128][129][130][131][132][133][134][135][136][137][138][139] ultrafiltration, [118,140] and nanofiltration. [141] However,i facatalyst in suspension is applied, membrane fouling is observed, especially in the case of micro-and ultrafiltration membranes. Moreover,t he quality of permeate is rather low because small molecules can easily pass through the membranes, even in the case of nanofiltration.…”

One of the most important applications for photocatalysis is engineered water treatment that photodegrades organic pollutants in wastewater at low cost. To overcome the low efficiency of batch degradation methods, continuous-flow photocatalytic reactors have been proposed and have become the most promising method for mass water treatment. However, most commercial semiconductor photocatalysts are granular nanoparticles with low activity and a narrow active light wavelength band; this creates difficulties for direct use in continuous-flow photocatalytic reactors. Therefore, a high-performance photodegradation photocatalyst with proper morphology or structure is key for continuous photocatalytic degradation. Moreover, a well-designed photocatalytic device is another important component for continuous-flow photocatalysis and determines the efficiency of photocatalysis in practical water treatment. This review describes the basic design principles and synthesis of photocatalysts with excellent performance and special morphologies suitable for a filtering photocatalysis process. Certain promising continuous photodegradation reactors are also categorized and summarized. Additionally, selected scientific and technical problems that must be urgently solved are suggested.
