The characterization of a spore laccase from Bacillus vallismortis fmb-103, isolated from textile industry disposal sites, is described. The activity was 6.5 U/g of dry spore with ABTS as the substrate. The enzyme was quite stable at high temperature. It retained more than 90% of its initial activity after 10h at 70 °C. The enzyme demonstrated broad pH stability in both acidic and alkaline cond...

A white-rot fungus, strain SQ01, was isolated from decayed wood in a temperate forest. The strain was identified as a member of genus Trametes, based on the morphological characteristics and a complete sequence analysis of its 18S rRNA gene and ITS region. Strain SQ01 was capable of decolorizing a variety of synthetic dyes, including azo, triphenylmethane, and anthraquinone dyes, with an optima...

DFT reactivity descriptors, the ultraviolet–visible spectra and hydrolysis mechanism of three cationic dyes [Malachite Green (MG), Brilliant (BG) Ethyl (EG)] are performed with several exchange–correlation functional (global GGA, hybrids range-separated). Using time-dependent density theory, theoretical absorption obtained obey trend for λmax: GGA > hybrid range-separated functional. Thanks to ...

A bacteria strain Bacillus thuringiensis RUN1identifiedby 16s RNA gene phylogenetic analysiswas used to decolorize malachite green, a triphenylmethane dye in simulated wastewater. The ability of the organism produce extracellular laccase and degrade were also investigated. Results showed that decolorized (84.67 ± 1.19 %) green at 40 mgl-1 within 6 h; decolorization was associated production by ...

A protein solution with the properties of a specific antiserum to the triphenylmethane dye methyl blue has been made by treating a solution of bovine gamma-globulin and the dye with alkali and then slowly neutralizing the alkali. Some success has been obtained also in the formation of antibodies from other serum proteins and by other denaturation-renaturation procedures. By heating solutions of...
