In the process of biodegradation azo dye, redox mediators (RMs) were found to significantly enhance removal efficiency. this work, biodegradable RMs deriving from lignin-based monomers prepared via peroxidation investigate whether similar chemicals present in lignin-rich streams biorefineries could be used for biological treatment dyes. The as-prepared characterized by fourier transform infrare...
Aerobic biodegradation behavior of nonylphenol monopropoxyethoxylates was investigated in two tests with different inocula-sewage sludge and river water. Both primary biodegradation and formation of different biodegradation intermediates were studied. Primary biodegradation of nonylphenol monopropoxyethoxylates was relatively fast and complete with the sewage sludge as the inoculum. On the othe...
Malachite green (MG), N-methylated diaminotriphenylmethane, is one of the most common dyes in textile industry and has also been used as an effective antifungal agent. However, due to its negative impact on the environment and carcinogenic effects to mammalian cells, there is a significant interest in developing microbial agents to degrade this type of recalcitrant molecules. Here, an Exiguobac...
Biodegradation of azo dyes is difficult due to their complex structures and low BOD to COD ratios. In the present study, the efficiency of using Fenton's reagent (H2O2 + Fe2+) as a pretreatment process to enhance microbial transformation of reactive black 5 (RB5) in an aqueous system was evaluated. The RB5 with an initial concentration of 250 mg/L was decolorized up to 90% in 60 h by using a ba...
Abstract This study identified a common Streptomyces sp. (MN262194) from forest soil as an efficient decolorizer of triphenylmethane (TPM) dyes. Partial 16S rRNA sequencing the isolate possibly bacillaris (similarity 99.32%). Live and dead cells were applied to decolorize Malachite Green (MG), Methyl Violet (MV), Crystal (CV), Cotton Blue (CB). The decolorization efficacy for both cell types wa...
This study investigated the biodegradation performance and characteristics of Sudan I and Acid Orange 7 (AO7) to improve the biological dye removal efficiency in wastewater and optimize the treatment process. The dyes with different water-solubility and similar molecular structure were biologically treated under aerobic condition in parallel continuous-flow mixed stirred reactors. The biophase ...
