Pandey, Deepshikha; Daverey, Achlesh; Dutta, Kasturi; Arunachalam, Kusum published an article in Chemosphere. The title of the article was 《Bioremoval of toxic malachite green from water through simultaneous decolorization and degradation using laccase immobilized biochar》.Related Products of 30931-67-0 The author mentioned the following in the article:
In this study, decolorization and degradation of malachite green dye was studied using the laccase immobilized pine needle biochar. Successful immobilization of biochar was achieved by adsorption and confirmed through SEM and energy dispersive X-ray anal. (SEM-EDX), Fourier transform IR spectroscopy (FTIR). High laccase binding of 64.4 U/g and high immobilization yield of 78.1% was achieved using 4U of enzyme at pH3 and temperature 30 °C. The immobilized laccase retained >50% relative activity in the pH range 2-7, >45% relative activity at 65 °C and >55% relative activity at 4 °C for 4 wk. The re-usability of immobilized enzyme was checked with 2, 2′-azino-bis 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) substrate and enzyme retained 53% of its activity after 6 cycles. Immobilized laccase was used for the degradation and decolorization of azo dye malachite green in aqueous solution More than 85% removal of malachite green dye (50 mg/L) was observed within 5 h. FTIR and high performance liquid chromatog. (HPLC) anal. clearly indicated the breakdown of dye and presence of metabolites (leuco malachite green, methanone, [4-(di-Me amino)pheny]phenyl and 3-dimethyl-Ph amine) in gas chromatog.-mass spectrometry (GC-MS) anal. confirmed the dye degradation Phytotoxicity anal. indicated that the enzymic degradation resulted in lesser toxic metabolites than the original dye. Thus, laccase immobilized biochar can be used as an efficient biocatalytic agent to remove dye from water. The experimental part of the paper was very detailed, including the reaction process of ABTS Diammonium(cas: 30931-67-0Related Products of 30931-67-0)
ABTS Diammonium(cas: 30931-67-0) belongs to anime. Acylation is one of the most important reactions of primary and secondary amines; a hydrogen atom is replaced by an acyl group (a group derived from an acid, such as RCOOH or RSO3H, by removal of ―OH, such as RC(=O)―, RS(O)2―, and so on). Reagents may be acid chlorides (RCOC1, RSO2C1), anhydrides ((RCO)2O), or even esters (RCOOR′); the products are amides of the corresponding acids.Related Products of 30931-67-0
