Decolorization is the process of removing natural pigment from chitin, which can be achieved through the addition of acetone or other chemicals, or through enzymatic hydrolysis or the use of microorganisms.

In this study, we investigated the production of ligninolytic enzymes by an endophyte M. cladophyllus during RBBR dye decolourisation and the possibility of these ligninolytic enzymes being differentially expressed during the decolourisation process.

2007年9月1日 · 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.

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%).

Within this review, we investigate the mechanisms by which diverse categories of microorganisms, such as the white-rot fungi and anaerobic bacterial consortia, bring about the degradation of dyestuffs. Received revision: 22 November 2000. Electronic Publication.

Decolourisation was dependent upon the presence of a carbon and energy source in addition to the textile dyes. PDW was capable of dye decolourisation when utilising cheap and readily available carbon sources such lactose, starch and distillery waste. PDW removed 76% of colour from textile plant effluent after 3 days.

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% …

Within this review, we investigate the mechanisms by which diverse categories of microorganisms, such as the white-rot fungi and anaerobic bacterial consortia, bring about the degradation of dyestuffs. Dyes and dyestuffs find use in a wide range of industries but are of primary importance to textile manufacturing.

Macroporous resin decolorization method is gaining lots of attention due to its large processing capacity, high efficiency and low loss. However, the current decolorization method commonly used in IN production is still activated carbon decolorization. Li Tao, ... Heyu Wang, in Trends in Food Science & Technology, 2023.

2020年4月9日 · A decolourisation of 94% in 1 min was achieved under optimised parameters, although mixing of dyes caused a retardation of mineralisation when compared with individual dyes. The study has established that treatment can be carried out at the natural pH of the dye solution in $${\text{Fe}}^{2 + }$$/SPS system.
