Modification of azo dyes by lactic acid bacteria.
AIM The ability of Lactobacillus casei and Lactobacillus paracasei to modify the azo dye, tartrazine, was recently documented as the result of the investigation on red coloured spoilage in acidified cucumbers. Fourteen other lactic acid bacteria (LAB) were screened for their capability to modify the food colouring tartrazine and other azo dyes of relevance for the textile industry. METHODS AN...
متن کاملDecoloration of textile dyes by alginate-immobilized Trametes versicolor.
Alginate-immobilized Trametes versicolor decolorized Amaranth at similar rates in repeated batch culture when the dye was present in either (i) modified Kirk's medium containing 0.22 gl(-1) ammonium tartrate, (ii) the same buffer, thiamine, trace elements and glucose concentrations as in the modified Kirk's medium, or (iii) glucose alone at either 1, 5 or 10 gl(-1). With glucose alone (0.5 gl(-...
متن کاملComparison of cytochrome P-450- and peroxidase-mediated activations of carcinogenic azo dyes and N-nitrosamines.
Carcinogenic azo dyes (dimethylaminoazobenzene, Sudan I) and N-nitrosamines (N-nitrosomethylaniline, N-nitrosomethylbenzylamine) are oxidized by cytochrome P-450 isoenzymes and peroxidase yielding metabolites which in vitro bind to DNA and transfer RNA (tRNA). The parallelism and differences in oxidative reactions are described. Peroxidase is more effective than P-450 in activating reactions of...
متن کاملDecolorization of Azo, Triphenyl Methane, Heterocyclic, and Polymeric Dyes by Lignin Peroxidase Isoenzymes from Phanerochaete chrysosporium.
The ligninolytic enzyme system of Phanerochaete chrysosporium decolorizes several recalcitrant dyes. Three isolated lignin peroxidase isoenzymes (LiP 4.65, LiP 4.15, and LiP 3.85) were compared as decolorizers with the crude enzyme system from the culture medium. LiP 4.65 (H2), LiP 4.15 (H7), and LiP 3.85 (H8) were purified by chromatofocusing, and their kinetic parameters were found to be simi...
متن کاملUltrafast degradation of azo dyes catalyzed by cobalt-based metallic glass
Reactivity and mass loss are considered mutually exclusive in conventional zero-valent metal (ZVM) technology to treat environmental contaminants. Here, we report the outstanding performance of Co-based metallic glass (MG) in degrading an aqueous solution of azo dye, thus eliminating this trade-off. Ball-milled Co-based MG powders completely degrade Acid Orange II at an ultrafast rate. The surf...
