“…As a sample dye for photocatalytic removal, we used Metanil Yellow (Figure 3) which is highly toxic and widely used in the food industry [45][46][47][48]. The process was conducted in a glass beaker of 50 mL volume under ambient temperature and pressure.…”

We investigate the possibility of modification of SnS2 powder through sonochemical synthesis with the addition of an organic ligand. For that purpose, two organic dyes are used, Phenol Red and Anthraquinone Violet. All obtained powders are characterized using XRD, SEM, EDX, FT-IR, and UV-Vis investigations. Synthesized samples showed composition and structural properties typical for sonochemically synthesized SnS2. However, investigation with the Tauc method revealed that SnS2 powder modified with Phenol Red exhibits a significant shift in value of optical bandgap to 2.56 eV, while unmodified SnS2 shows an optical bandgap value of 2.42 eV. The modification of SnS2 powder with Anthraquinone Violet was unsuccessful. The obtained nanopowders were utilized as photocatalysts in the process of Metanil Yellow degradation, revealing that SnS2 modified with Phenol Red shows about 23% better performance than the unmodified one. The mean sonochemical efficiency of the performed synthesis is also estimated as 9.35 µg/W.

The azo dye orange II is used extensively in the textile sector for coloring fabrics. High concentrations of it are released into aqueous environments through textile effluents. Therefore, its removal from textile wastewater and effluents is necessary. Herein, initially, we tested 11 bacterial strains for their capabilities in the degradation of orange II dye. It was revealed in the preliminary data that B. subtilis can more potently degrade the selected dye, which was thus used in the subsequent experiments. To achieve maximum decolorization, the experimental conditions were optimized whereby maximum degradation was achieved at: a 25 ppm dye concentration, pH 7, a temperature of 35 °C, a 1000 mg/L concentration of glucose, a 1000 mg/L urea concentration, a 666.66 mg/L NaCl concentration, an incubation period of 3 days, and with hydroquinone as a redox mediator at a concentration of 66.66 mg/L. The effects of the interaction of the operational factors were further confirmed using response surface methodology, which revealed that at optimum conditions of pH 6.45, a dye concentration of 17.07 mg/L, and an incubation time of 9.96 h at 45.38 °C, the maximum degradation of orange II can be obtained at a desirability coefficient of 1, estimated using the central composite design (CCD). To understand the underlying principles of degradation of the metabolites in the aliquot mixture at the optimized condition, the study steps were extracted and analyzed using GC-MS(Gas Chromatography Mass Spectrometry), FTIR(Fourier Transform Infrared Spectroscopy), 1H and carbon 13 NMR(Nuclear Magnetic Resonance Spectroscopy). The GC-MS pattern revealed that the original dye was degraded into o-xylene and naphthalene. Naphthalene was even obtained in a pure state through silica gel column isolation and confirmed using 1H and 13C NMR spectroscopic analysis. Phytotoxicity tests on Vigna radiata were also conducted and the results confirmed that the dye metabolites were less toxic than the parent dye. These results emphasize that B. subtilis should be used as a potential strain for the bioremediation of textile effluents containing orange II and other toxic azo dyes.

“…Moreover, the utilization of gellan gum as the immobilization matrix provided an extra edge in comparison to calcium alginate. The interaction between gellan gum and ions is nonspecific which allows the gel to interact with multiple cations which is not achievable with other ion -sensitive gelling polysaccharides such calcium alginate [8].…”

“…Gellan gum appears to be a finest biological polymer for entrapment of active enzymes. This immobilization matrix has better rheological characteristics in comparison to that of agar and carrageenan gels when assessed at similar concentrations [8]. Besides, the hydrogels are able to sustain stability over a broad pH range which is from 2 to 10 [9].…”

Conversion of waste cooking oil by rhodococcal lipase immobilized in gellan gum

et al. 2021

Recently, the application of lipase enzyme as biocatalyst in the conversion of waste cooking oil (WCO) to free fatty acids and glycerol has been trending well. Therefore, the present study attempts to use WCO which is found in abundance in Malaysia as the substrate for halal microbial lipase conversion to glycerol which can be exploited in the food industry. The workability of free lipase for WCO conversion, however suffers severely due to potential denaturation of the enzyme and extended reaction time. Thus, this study embraced the immobilization method to encapsulate crude lipase extracted from Rhodococcus pyridinivorans strain UCC 0009 in gellan gum and calcium alginate, respectively and compared their ability for WCO conversion to free crude lipase. The gellan gum and calcium alginate-immobilized crude lipase evidently exhibited greater WCO conversion, demonstrating 2.18-fold and 1.61-fold enhanced lipase activity, respectively in comparison to free crude lipase. The repeated reuse of the gellan gum-immobilized crude lipase maintained reasonable lipase activity for 9 cycles, retaining an average 85 % WCO conversion for the first seven cycles and 67 % conversion in the subsequent batches. Thus, the immobilized halal lipase can be foreseen as a green substitute to chemical catalyst for WCO conversion which meets the worldwide demand for clean technologies.
