Streptomyces Consortium for Enhanced Biodegrdation of Azo Blue Dye

open access: yesJournal of Pure and Applied Microbiology, 2018
A Streptomyces consortium was developed and investigated for biodegradation of reactive sulfonated di azo dye (Reactive Blue 222). The biodegradation of azo blue dye by the consortium was further assessed with different ratios of inoculum of two ...

Predicting dye biodegradation from redox potentials [PDF]

open access: yes, 2004
Two biological approaches for decolorization of azo sulfonated dyes have been compared: reductive decolorization with the ascomycete yeast Issatchenkia occidentalis and nzymatic oxidative decolorization with Trametes villosa laccase alone or in the ...

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

open access: yesQuímica 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,

Effect of Solvent on Azo-Hydrazonetautomerism of 2-Hydroxy-5-(4-Nitrophenylazo) Benzaldehyde [PDF]

open access: yes, 2015
Azo dye has been synthesized having Donor-p-Acceptor (D-p-A) system to study the effect of solvent on the azo-hydrazone tautomerism. The relative stabilities of azo and hydrazone tautomer are examined by means of UV-Vis spectroscopic technique and are ...

Changes of fatty acid metabolism and oxidative phosphorylation of rat liver mitochondria during 3'-Me-DAB feeding [PDF]

open access: yes, 1964
Respiration, activity of oleate oxidation and composition of the total fatty acids of rat liver were investigated in 3'-Me-DAB feeding. 1. Oxidative phosphorylation of rat liver mitochondria decreased temporarily at relatively earlier stages (about 2 to ...
