“…This result matched that found in Streptomyces (Zacchetti et al, 2018). Likely, lactic acid bacteria adsorbed Dorasyn Red azo dye showed smoother cell surfaces from dye coating pores of biomass (Sofu, 2019); also in fungi, the surface of Aspergillus niger filaments was coated with small particles (0.1-1.0 m) after adsorbing acid dyes (Li et al, 2019). According to the results, the decolorization mechanism of S. coelicoflavus CS-29 may occur by adsorption of dyes in the cell pellets.…”

Azo dyes are used for silk textile manufacture, where their decolorization and detoxication are necessary after initial dying in the craft industry. The bio-decolorization efficiency of Streptomyces coelicoflavus CS-29 toward commercial azo blue and red dyes was investigated, analyzing the degradation and adsorption of dye molecules. S. coelicoflavus CS-29 showed reductions of 70% and 51% in red and blue dyes, respectively, after seven days. Morphological observation by light microscopy showed that dye molecules were adsorbed onto S. coelicoflavus CS-29 cell surface to form a dense cell pellet. Moreover, peroxidase and laccase activity were detected as extracellular enzymes, but no azo-reductase was detected. From the enzymatic activity, changes of dye profiles in HPLC showed differences between control dyes (untreated dyes) and metabolized products of dyes treated with S. coelicoflavus CS-29. The presence of main functional azo groups (-N=N-) in both blue and red silk dyes was indicated by FTIR analysis, in the untreated azo dyes. The azo bonds seemed to disappear in metabolites after S. coelicoflavus CS-29 treatment and other functional groups were changed compared to the control dyes. The treated dyes showed no significant effect on seed germination, root length, and shoot length of mung beans during phytotoxicity analysis. The red dyes showed a more negative effect on shoot lengths than the blue dyes. The overall results showed that S. coelicoflavus CS-29 is an effective and promising tool for the treatment of dye contaminated wastewater and the permanent elimination of recalcitrant commercial azo dye pollutants.

“…Environmental pollution caused by heavy metals is a serious and complicated problem, which has been a focus of attention around the world . Heavy metals, unlike organic contaminants, are not biodegradable and tend to accumulate in living organisms and most of them may damage the liver of the organisms and cause many fatal diseases .…”

The morphology and structure of as‐prepared aluminum silicon carbide (Al4SiC4) were characterized using X‐ray diffraction (XRD) patterns, scanning electron microscope (SEM), transmission electron microscopy (TEM) and UV‐vis spectra. The Al4SiC4 nanoparticles modified glassy carbon electrode (GCE) was further investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Based on this, this kind of new electrode was used for the detection of trace Cu2+ by square wave anodic stripping voltammetry (SWASV) for the first time. The electrochemical parameters influencing on deposition and stripping of metal ions, such as supporting electrolytes, pH value, deposition potential and deposition time, were also optimized. The results showed that the Al4SiC4 modified GCE exhibited excellent stripping response of Cu2+ and the stripping peaks response increased linearly with increasing concentration of Cu2+ in the ranges of 400 to 2200 nM. Under the optimized conditions the favorable sensitivity of the Al4SiC4 modified GCE toward trace Cu2+ was 1.49 μA μM−1 and the limit of detection (S/N=3) was estimated to be 2.76 nM. More importantly, Al4SiC4 modified GCE had an excellent stability and negligible interference from other coexisting metal ions in the electrochemical determination of Cu2+.
