Effect of dye structure and redox mediators on anaerobic azo and anthraquinone dye reduction

Química Nova, 2012
We investigated the biological decolourisation of dyes with different molecular structures. The kinetic constant values (k1) achieved with azo dye Reactive Red 120 were 7.6 and 10.1 times higher in the presence of RM (redox mediators) AQDS and riboflavin,

Azo Dyes and Heinz Bodies [PDF]

Occupational and Environmental Medicine, 1957
No general hypothesis has been advanced to explain the underlying cause of the appearance of Heinz bodies in erythrocytes. The initial observation of Riess (1882) on a case of potassium chlorate poisoning was followed by that of Heinz (1890) who administered phenylhydrazine to animals.

Potential and prospects of reductases in azo dye degradation: a review

The Microbe
Synthetic dyes, particularly azo dyes, pose environmental and health risks because of their toxicity and persistence. To reduce these negative effects, it is necessary to degrade and detoxify these dyes into simple, non-toxic substances.
