Improved conditions for the aerobic reductive decolourisation of azo dyes by Candida zeylanoides [PDF]

, 2002
A number of anaerobic and aerobic bacterial species are known to decolourise azo dyes through the reduction of the azo bonds, forming the corresponding amines.

Enhanced Microbial Sensing via Resazurin Reduction Catalyzed by Graphene Oxide, A Versatile Approach for Diagnostics and Electrochemical Applications

Environmental Toxicology, EarlyView.
ABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the

Contact Allergy to Ingredients of Hair Cosmetics Associated with Occupational and Non‐Occupational Exposure—Trends from 1995 to 2020 in Central Europe, with or without Regulation

Contact Dermatitis, EarlyView.
Among 2678 female hairdressers and 6244 female consumers with contact dermatitis suspected to be related to use of hair cosmetics, including dyes, patch tested in the IVDK between 1995 and 2020, diverging contact allergy trends were observed. In the case of toluene‐2,5‐diamine (PTD) shown in the figure, sensitization was at a stable, high level in ...

The plasticisation model of dye diffusion: Part 6

Coloration Technology, EarlyView.
Abstract Previously published data reported for the temperature dependency of the exhaustion of a mordant dye and acid dye, as well as both the exhaustion and fixation of a reactive dye and adsorption of a direct dye, on three different types of wool substrate, over a diverse range of dyeing temperatures and conditions, were re‐evaluated using the ...

Textile Effluent Containing Azo Dyes Eco-Friendly Bioremediation using Lentinus sp. in a Packed-Bed Bioreactor with Pine Sawdust as an Organic Inducer

Universitas Scientiarum
Industrial textile effluents containing azo dyes pose a major environmental challenge due to their persistence and toxicity. This study evaluated the capacity of a native white-rot fungus (Lentinus sp.) to treat a real textile effluent polluted with an ...

Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

The FEBS Journal, EarlyView.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...
