• Analysis of the variants showed that Trp164 is required for oxidation of two high redox potential model substrates (veratryl alcohol and Reactive Black 5), whereas the two other pathways (starting at His232 and His82) are not involved in long-range electron transfer (LRET) [2].
• As a control group we have used dye-exposed workers with IgE antibody to Remazol Black B, a diazo dye containing the vinyl sulfone-reactive group [3].
• Sera from three patients, occupationally exposed to a reactive dye, Remazol black B (Chemical Abstract registry number 17095-24-8), were used [4].
• In this work, aqueous solutions of a simple azo dye with a low molecular weight (C.I. Acid Yellow 9) and more complex commercial dye (C.I. Reactive Black 5) were electrochemically treated in a laboratory-scale electrolytic cell in sodium chloride or ammonium acetate as supporting electrolytes [5].
• Amination substantially enhanced RB5 adsorption by eliminating acidic groups and creating a positive charge on the surface of MN-8 [6].

• Monitoring of the anaerobic degradation of the diazo Reactive Black 5 displays the dependency of a two stage azo group reduction mechanism on the redox potential of the bioreactor [13].
