“…6: MG was hydroxylated to form malachite green carbinol in the first step, which then oxidized and decomposed into (dimethyl amino-phenyl)-phenyl-methanone and N,N-dimethylaniline; the (dimethyl amino-phenyl)-phenyl-methanone was then decomposed into (amino phenyl)-phenyl methanone through a stepwise demethylation process; and di-benzyl methane and N,N-dimethylaniline were the final products detected in this study. The previous literature has indicated that the first step of the biodegradation of MG was either a direct stepwise demethylation process or a reduction reaction followed by a stepwise demethylation process (Chen et al 2009(Chen et al , 2010Li et al 2009). The degradation pathway of MG by bacteria usually begins with a reduction reaction followed by a stepwise demethylation process, while the degradation pathway of MG by fungi mediated by laccase usually begins with a direct stepwise demethylation process (Chen et al 2009(Chen et al , 2010Li et al 2009).…”

“…These methods are not only costly and inefficient, but also produce large amounts of sludge. Therefore, as an ecofriendly, efficient and low cost alternative, biological treatment of MG has been receiving more and more attentions (Chen et al 2009;Wu et al 2009). …”

Malachite green (MG), a widely-used and recalcitrant dye, has been confirmed to be carcinogenic and mutagenic against many organisms. The main objective of this study is to investigate the capability of Pseudomonas sp. strain DY1 to decolorize MG, and to explore the possible mechanism. The results showed that this strain demonstrated high decolorizing capability (90.3-97.2%) at high concentrations of MG (100-1,000 mg/l) under shaking condition within 24 h. In static conditions, lower but still effective decolorization (78.9-84.3%) was achieved. The optimal pH and temperature for the decolorization was pH 6.6 and 28-30°C, respectively. Mg(2+) and Mn(2+) (1 mM) were observed to significantly enhance the decolorization. The intermediates of the MG degradation under aerobic condition identified by UV-visible, GC-MS and LC-MS analysis included malachite green carbinol, (dimethyl amino-phenyl)-phenyl-methanone, N,N-dimethylaniline, (methyl amino-phenyl)-phenyl-methanone, (amino phenyl)-phenyl methanone and di-benzyl methane. The enzyme analysis indicated that Mn-peroxidase, NADH-DCIP and MG reductase were involved in the biodegradation of MG. Moreover, phytotoxicity of MG and detoxification for MG by the strain were observed. Therefore, this strain could be potentially used for bioremediation of MG.

“…Among the identied genera in the inoculum, Pandoraea (5.49%), Comamonas (3.81%) and Delia (1.70%) were reported to possess the abilities of azo dye decolorization and nitro-compound reduction. [25][26][27][28] Most of the genera from the inoculum were not reported to reduce azo dye and nitro directly. All of the dominant genera in the inoculum were at the same order of magnitude.…”

ÖZTekstil boyama endüstrisinde kullanılan Bazik Mavi 3 boyarmaddesinin alüminyum elektrot kullanılarak elektrokimyasal olarak tekstil atık sularından giderimi üzerinde çalışılmıştır. Kesikli proses ile yapılan deneyler sonrasında 10 dakika sonunda pH8 değerinde %97'den fazla giderim etkinliği hesaplanmıştır. Elektrokimyasal işlemin 6. dakikası sonunda 50-400 mg/L aralığındaki konsantrasyonlardaki boya giderim etkinliği %92-95 arasında değişirken bu oran, 500 ve 600 mg/L için sırasıyla %72 ve %60 olarak hesaplanmıştır. 10. dakika sonunda ise bütün konsantrasyon değerlerindeki boya giderim oranı %96 civarındadır. Akım yoğunluğu değerlendirildiğinde ise boya giderim etkinliği 333 A/m 2 akım yoğunluğu ile 4. dakikadan sonra (%96) işlem bitene kadar çok fazla bir artış göstermemiş ve 10. dakikada %97 seviyesine ulaşmıştır.Anahtar Kelimeler: elektrokoagülasyon, tekstil atık suları, bazik mavi 3, alüminyum elektrot Removal of C.I. Basic Blue 3 dyestuff from textile waste waters by electrochemical treatment ABSTRACTThe present study investigates the electrochemical treatment of Basic Blue 3 dyestuff from the textile waste waters. We achieved more than 97% color removal with pH8 after 10 minutes. In terms of initial dye concentrations, 92-95%, 72 and 60% dye removal efficiencies were obtained in 6 minutes for 50-400 mg/L, 500 and 600 mg/L initial dye concentrations respectively. In 10 minutes removing efficiencies became 96% for all the concentrations. When we consider the current density parameter, 96% removal efficiency was obtained with 333 A/m 2 current density in 4 minutes respectively. However the removal efficiency only increases to 97% in 10 minutes.
