“…The optimization of conditions for enhanced decolorization of dye RB 172 was carried out by one parameter approach at a time. Initially, the effect of microaerophilic and aerobic incubation (shaking at 120 rpm), preenriched culture medium pH (3)(4)(5)(6)(7)(8)(9)(10)(11)(12), incubation temperature (20,30,37,40, and 50 ± 0.2 ∘ C), and dye concentrations (50-250 mg L −1 ) was evaluated. At defined time of intervals the aliquots of culture supernatant (3 mL) were withdrawn and suspended particles were removed by adding equal volume of methanol followed by centrifugation (7500 ×g for 15 min, 4 ± 0.2 ∘ C) [13].…”

“…But some shortcomings such as excessive use of chemicals, secondary pollution, large amount of sludge generation, low efficacies, and high operational cost discourage the employment of these methods [10]. Alternatively, the modern method bioremediation, which utilizes the ability of bacteria, fungi, or its combination system, has emerged as an effective method for the treatment of textile wastewaters [11][12][13]. However, higher price of microbial growth medium makes biological treatments expensive and beyond the use at commercial levels.…”

Present study focuses on exploitation of agricultural waste wheat bran (WB) as growth medium for degradation of textile azo dye C.I. Reactive Blue 172 (RB 172) using a single bacterium P. rettgeri strain HSL1 (GenBank accession number JX853768.1). The bacterium was found to completely decolorize 50 mg L −1 of dye RB 172 within 20 h at 30 ± 0.2 ∘ C under microaerophilic incubation conditions. Additionally, significant reduction in COD (85%) and TOC (52%) contents of dye decolorized medium was observed which suggested its mineralization. Induction in the activities of azoreductase (159%) and NADH-DCIP reductase (88%) provided an evidence for reductive cleavage of dye RB 172. The HPLC, FTIR, and GC-MS analysis of decolorized products confirmed the degradation of dye into various metabolites. The proposed metabolic pathway for biodegradation of RB 172 has been elucidated which showed the formation of 2 intermediate metabolites, namely, 4-(ethenylsulfonyl) aniline and 1-amino-1-(4-aminophenyl) propan-2-one. The acute and phytotoxicity evaluation of degraded metabolites suggests that bacterial strain favors the detoxification of dye RB 172. Thus, WB could be utilized as a low-cost growth medium for the enrichment of bacteria and their further use for biodegradation of azo dyes and its derivatives containing wastes into nontoxic form.

“…Obtaining high percentages of removal in short periods of time is a very desirable factor when working with white rot fungi since executing scaling of processes where retention times are short is best to be able to treat larger wastewater volumes. Therefore, these unconventional systems could become competitive if compared to biological systems using aerobic or anaerobic bacteria (Hai et al, 2013, Ma et al, 2014. Regarding glucose consumption, it was observed that in the experiments with dyes, P. ostreatus was able to perform the remotion using low glucose concentrations (< 5 g L -1…”

“…According to the results in the presence of CV, productivity was lower at 216 hours and increased from 0.052 to 0.159 UL -1 h -1 when the analysis was carried out at 72 h. In the absence of dyes, the results were lower for both 72 and 216 h (0.075 and 0.0029 UL -1 h -1 respectively). If these results are related to the percentage of decolorization, removal kinetics for CV could be successful in just 72 h; saving 144 h in processing time (Ma et al, 2014).…”

Partial removal and detoxification of Malachite Green and Crystal Violet from laboratory artificially contaminated water by Pleurotus ostreatus

et al. 2016

The triphenylmethane Malachite Green (MG) and Crystal Violet (CV) dyes are cationic dyes and mix with domestic wastewater when dumped; increasing, among others, the chemical and biological oxygen demand and can cause acute toxicity at different trophic levels. Promoting the removal (decolorization) of MG and CV, and laccase activity (54.8 ± 8.9 and 30.6 ± 2.9 UL -1 respectively) by using P. ostreatus viable biomass needed parameters such as pH (4.5 and 6.0), temperature ). In adsorption studies, it was showed that an acidic pH favors the adsorption of both dyes and the model of pseudo-second order describes best the phenomenon of adsorption. Finally, the germination index (GI), using Lactuca sativa seeds for the initial dyes solutions, was < 50%; demonstrating its high phytotoxic effect. When dye solutions were treated with viable biomass, the GI increased, leaving open the possibility to perform future research to determine if the aqueous solutions, post-treated with P. ostreatus, could be used in treatments that generate less toxic water which could be used in processes that do not require potable water.

“…The equation of the line for determining the concentration of methylene blue was y = 0.09875+011646x, R 2 = 0.9947, where y = absorbance and x = concentration of the dye (mg L -1 ). The percentage of dye degradation (DC) was determined via DC (%) = [(AC -AF) ⁄AC] x 100, where AC = absorbance of the culture medium in the control treatment (without fungi) and AF = absorbance of the culture medium with the fungi according to the methodology of Ma et al (2014).…”

Bioremediation potential of filamentous fungi in methylene blue: Solid and liquid culture media

et al. 2017

The evaluation of the bioremediation potential of microbial with dyes in solid and liquid culture media has been described, but prior studies have not mentioned which culture method is most appropriate for selection of microorganisms. Therefore, the aim of this work was to evaluate the bioremediation potential of filamentous fungi in liquid and solid culture media with methylene blue. The fungi isolates tested were Pleurotus ostreatoroseus (POR-SP1, POR-SP2), P. ostreatus (DF39, EF58 and EF60), Pycnoporus sanguineus (PS) and Fusidium sp. (FUS). The methylene blue concentrations tested were 0, 5, 10, and 50 mg L -1 in the solid medium and 0, 5, 25, 50, and 100 mg L -1 in the liquid medium. In the solid medium, the mycelial diameters of DF39, EF58, FUS, and PS were not influenced by the increase in dye concentration. In the liquid medium, DF39, EF58, EF60, and FUS showed a constant methylene blue degradation rate with increasing dye concentration. The dye degradation rate was correlated with the pH of the liquid medium for EF58, EF60, and FUS. The lower diameter growth in the solid medium did not influence the methylene blue dye degradation rate in the liquid medium.Index terms: Environmental microbiology; biodegradation; dye. RESUMOA avaliação do potencial biorremediador microbiano com corantes é descrita em meio de cultura sólido e líquido, mas não é mencionado qual método de cultivo é o mais apropriado na seleção de microrganismos. Para tanto, o objetivo deste trabalho foi avaliar o potencial de biorremediação de fungos filamentosos, em meios de cultura líquido e sólido com azul de metileno. Os isolados fúngicos testados foram: Pleurotus ostreatoroseus (POR-SP1 e POR-SP2), P. ostreatus (DF39, EF58 e EF60), Pycnoporus sanguineus (PS) e Fusidium sp. (FUS). As concentrações de azul de metileno testadas foram 0, 5, 10 e 50 mg L -1 em meio sólido e de 0, 5, 25, 50 e 100 mg L -1 em meio líquido. No meio sólido, o diâmetro micelial de DF39, EF58, FUS e PS não foi influenciado pelo aumento da concentração de corante. Em meio líquido, DF39, EF58, EF60 e FUS apresentaram degradação do azul de metileno constante com o aumento da concentração do corante. A taxa de degradação do corante foi correlacionada com o pH do meio líquido, para EF58, EF60 e FUS. O menor crescimento, em diâmetro, em meio sólido, não influenciou na taxa de degradação do corante azul de metileno, em meio líquido.
