“…Reactive Black 5 (CAS No. 17095-24-8, MW 991.82, λ max = 597 nm, Sigma-Aldrich) has been often used as the model contaminant in the study of dye removal (Lima Beluci et al 2019;Zhang et al 2019). Before using RB5 stock solution, it was filtered through a 0.22-μm aqueous phase needle filter and then stored at 4 °C.…”

Industrial wastewater with refractory dyes is still considered as one kind of serious pollution. Biological treatments have shown great potential for the biodegradation of dyes. A new natural bacterial flora DDMY1 with efficient decolorization performance of azo dye reactive black 5 (RB5) was obtained from activated sludge by concentration gradient domestication. Morphological analysis, growth test, decolorization assay of different parameters, kinetics study and high-throughput sequencing were performed in this study. Morphological analysis showed the features of flora DDMY1 and growth curves emerged the temperature range suitable for the growth of flora DDMY1. Results of decolorization assays indicated that xylose and yeast extract could enhance the decolorization effect and flora DDMY1 could decolorize RB5 not only in wide ranges of pH values (4.0-9.0) and initial dye concentration (100-1000 mg L −1 ), but also in the optimum temperature (40 °C) and NaCl concentration (1.5%, w/v). Kinetics study of RB5 decolorization at 30-40 °C conformed to the first-order kinetic reaction equation. High-throughput sequencing analysis revealed the community structure of flora DDMY1 and the dominant genus unclassified_o_Pseudomonadales, which had synergistic effect on decolorization with unclassified_f_Alcaligenaceae, Pseudomonas and other genera. Findings of this study revealed a sort of natural bacterial flora that could accommodate different wastewater conditions and remove high-concentration refractory dyes efficiently. These results also indicated the possibility of treating dyeing wastewater on a large scale with different conditions.

“…These dyes are discharged into water bodies, which can reduce the light penetration and oxygen transfer, resulting in changes to photosynthesis and aquatic ecosystems. 3 Dyes are usually physically and chemically stable in the natural environment and therefore they are highly recalcitrant and harmful to living things. 4 Given the refractory dye-containing wastewater, numerous physical and chemical treatment methods have positive effects on the removal of such wastewater.…”

“…It is well known that different culture media have a direct impact on the metabolic activity of microorganisms and this can be analyzed through untargeted-metabolomics, quantitative proteomics, or transcriptome sequencing (Lv et al, 2019;Zhang Q. Y. et al, 2019;Zheng et al, 2020). To explore the possible mechanism of dye enhanced decolorization by addition of FG, differentially expressed genes were analyzed by comparative transcriptome analysis in this study.…”

In this study, a white rot fungus Antrodia was newly isolated and named P5. Then its dye biodegradation ability was investigated. Our results showed that P5 could effectively degrade 1,000 mg/L Reactive Blue 4 (RB4) in 24 h with 95% decolorization under shaking conditions. It could tolerate a high dye concentration of 2,500 mg/L as well as 10% salt concentration and a wide range of pH values (4–9). Herbal extraction residues (HER) were screened as additional medium elements for P5 biodegradation. Following the addition of Fructus Gardeniae (FG) extraction residue, the biodegradation performance of P5 was significantly enhanced, achieving 92% decolorization in 12 h. Transcriptome analysis showed that the expression of multiple peroxidase genes was simultaneously increased: Lignin Peroxidase, Manganese Peroxidase, Laccase, and Dye Decolorization Peroxidase. The maximum increase in Lignin Peroxidase reached 10.22-fold in the presence of FG. The results of UV scanning and LC-HRMS showed that with the synergistic effect of FG, P5 could remarkably accelerate the biodegradation process of RB4 intermediates. Moreover, the fungal treatment with FG also promoted the abatement of RB4 toxicity. In sum, white rot fungus and herbal extraction residue were combined and used in the treatment of anthraquinone dye. This could be applied in practical contexts to realize an efficient and eco-friendly strategy for industrial dye wastewater treatment.
