Azo Dye Acid Blue 29: Biosorption and Phytotoxicity Test

Bile Acid Involvement in Azo Dye Carcinogenesis1

the early stages of liver carcinoma development in Sprague-Dawley rats. Bile acids were analyzed in urine and feces of azo dye-fed and control rats with the use of gas chromatography during the first 66 days of treatment. Seven bile acids were identified in the feces, with deoxycholic acid being the primary excretion product. During the first 36 days of 3'-methyl-4-dimethylaminoazobenzene feedi...

Immobilized laccase mediated dye decolorization and transformation pathway of azo dye acid red 27

BACKGROUND Laccases have good potential as bioremediating agents and can be used continuously in the immobilized form like many other enzymes. METHODS In the present study, laccase from Cyathus bulleri was immobilized by entrapment in Poly Vinyl Alcohol (PVA) beads cross-linked with either nitrate or boric acid. Immobilized laccase was used for dye decolorization in both batch and continuous ...

Phytotoxicity of methylene blue to rice seedlings

Methylene blue is widely used in various industrial branches. Due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. Hydroponic experiments were conducted with rice seedlings (Oryza sativa L. cv. XZX 45) exposed to methylene blue to determine the effective concentration using relative gr...

Batch Removal of Acid Blue 292dye by Biosorption onto Lemna minor: Equilibrium and Kinetic Studies

Background; Recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. Therefore, the aim of this study was to determine the feasibility of using Lemna minor for Acid Blue 292 (AB292) dye removal from aqueous solution and to determine the optimal conditions. Methods; This experimen...
