Decolourisation of textile dye by laccase: Process evaluation and ...
网页2021年11月1日 · Optimization of dye decolourisation by one variable at a time (OVAT) approach resulted in optimal dye decolourisation at laccase dose (2 IU mL −1), pH (7.0), temperature (35 °C), incubation time (240 min), and initial dye concentration (100 mg L-1). The optimized process through BBD enhanced dye decolourisation (97.18%).
A review on the laccase assisted decolourization of dyes: Recent …
网页2023年10月1日 · In this review, properties of laccase based on the source, mechanism of laccase-mediated dye decolourization, factors and operational parameters which affects the dye decolourization efficiency, different supports utilized for the immobilization of laccase, synergistic effect of laccase and its future prospects have been highlighted.
Review paper on current technologies for decolourisation of …
网页2007年9月1日 · The reductive decolourisation of azo dyes under anaerobic conditions is a combination of both biological and chemical mechanisms. The biological contribution can be divided in specialised enzymes called azo reductases, which are present in bacteria that are able to grow using only azo dye as a carbon and energy source.
Review paper on current technologies for decolourisation of …
网页Different microorganisms such as aerobic and anaerobic bacteria, fungi and actinomycetes have been found to catalyse dye decolourisation. Moreover, promising results were obtained in accelerating dye decolourisation by adding mediating compounds and/or changing process conditions to high temperatures.
Frontiers | Current Development in Decolorization of Synthetic …
网页2020年9月29日 · A proposed mechanism of dye degradation by immobilized laccase with the aid of the crystal structure of laccase from Thermus thermophilus HB27 (PDB code: 5JRR). Immobilized laccases proved to be worthy challengers for the effective decolorization, degradation, and removal of dyes (Bilal et al., 2019).
Microbial decolourisation and degradation of textile dyes
网页The ability of microorganisms to decolourise and metabolise dyes has long been known, and the use of bioremediation based technologies for treating textile wastewater has attracted interest.
Decolourisation of triphenylmethane dyes by biogenically …
网页The efficacy of the synthesised Fe-NPs in decolourizing triphenylmethane dyes was evaluated. Results revealed that fungal extract from F. proliferatum was successfully used to synthesise Fe-NPs. The Fe-NPs produced were 20–50 nm in size, and consist of substantial elemental Fe content (14.83%).
Decolourisation of Real Industrial and Synthetic Textile Dye …
网页2023年3月17日 · The most significant percentages of decolourisation observed were 98.7% for real textile dye wastewater (RTDW) and 78.0% for synthetic textile dye wastewater (STDW), while for chemical oxygen demand, reductions were 66.7% for RTDW and 73.9% for STDW, respectively.
Decolourisation of reactive dyes with laccase-mediator system
网页2020年11月18日 · Decolourisation with laccase has been found to be a promising technology in waste water treatment. However, selection of mediator remains a crucial factor. Social implications. Reactive dyes are self-hydrolysed over time under natural conditions and extent of decolourisation depends on concentration of …
High Potential Decolourisation of Textile Dyes from Wastewater …
网页2022年5月9日 · Among 16 different white-rot fungal isolates, Trametes hirsuta PW17-41 revealed high potential for decolourisation of mixed textile dyes (Navy EC-R, Ruby S3B and Super Black G) from real industrial wastewater samples. The efficiency of dye decolourisation was evaluated using the American Dye Manufacturers’ Institute (ADMI) standard methodology.
