“…Unlike Ponceau S Red that evidenced a positive effect on germination, according to the parameters described by Lago-Vila et al, 43 which indicate a G index : of >110%, these are classified as species with a stimulation effect. Results could be attributed to the use Ponceau S Red as a source of carbon and energy and at the same time to the enrichment of the culture medium with essential nutrients such as potassium, phosphorous, nitrogen, and calcium among others, a favorable environment for the growth of the plant system as reported by Zimmermann et al 44 and Bhattacharya et al 45 These positive effects (phytostimulators) were previously reported by Bhattacharya et al 45 in a study that clearly demonstrated the phytostimulatory effects of dyes on the growth of rice seeds.…”

“…Decolorization Assay. Dye decolorization was studied using the one-factor optimization approach: The influence of various culture conditions such as pH (3, 5, 7, 9, and 11), temperature (20,37,40,45, and 50 °C), the time of incubation (24,48,72,96, and 120 h), and concentration (50, 100, 200, 300, 400, 500, 600, 800, and 1000 mg/L) of dyes on the rate of decolorization was studied. When investigating one of these factors, all others were kept constant.…”

Franconibacter sp., 1MS: A New Strain in Decolorization and Degradation of Azo Dyes Ponceau S Red and Methyl Orange

The aim of the present study is focused on the decolorization and degradation of azo dyes Ponceau S Red and Methyl Orange by a bacterial strain isolated from the gold mining district of San Martin de Loba, South of Bolivar (Colombia) sediment samples and identified as Franconibacter sp. 1MS (GenBank: MT568543) based on phenotypic and genotypic methods. A higher percentage of decolorization at 100 mg/L concentration, 37 °C, and pH 7 was recorded at 120 h of incubation period for both dyes. The UV–vis, Fourier transform infrared spectroscopy, and gas chromatography–mass spectrometry analysis of the original dyes and their degraded metabolites confirmed that the decolorization was due to degradation. The proposed metabolic pathways for biodegradation of both dyes have been elucidated, which showed the formation of five intermediate metabolites, namely, N,N-dimethylbenzyl-1,4-diamine, sulfonamide, 1,4-diaminobenzene, 2,5-diaminobenzenesulfonic acid, and 1-amino-2-naphthol, which are not only highly toxic but also be able to be converted through metabolic activation into mutagenic, carcinogenic, and/or teratogenic species. The phytotoxicity studies of the original dye and degraded metabolites were tested on Phaseolus vulgaris and divulged that the degraded metabolites have toxic effects. An effective phytostimulation was observed in Ponceau S Red, which could be attributed to its capacity for enrichment of the culture medium with essential nutrients, a favorable environment for the growth of the plant.

“…The IR-spectra obtained from this fraction showed many similarities with other polysaccharide IR-spectra ( Qian et al, 2009 ). The strong broad band in the region of 3348 and 3373 cm −1 in the IR-spectrum can be assigned to the stretching vibrations of hydroxyl groups ( Qian et al, 2018 ), whereas the absorption bands at about 2932 and 2933 cm −1 can be related to the C-H stretching vibrations of CH 2 groups ( Bhattacharya et al, 2014 ). The signals at 1595 and 1598 cm −1 could be antisymmetric stretching peaks of carboxylate ions ( He 2015 ).…”

In this study water soluble compounds that form complexes with Rare Earth Elements (REE) and other metals were isolated from Calothrix brevissima biomass with chromatographic methods for the first time. Molecular characterization showed that the isolated compounds are most likely polysaccharides comprised of arabinose, xylose, mannose, galactose and glucose. FT-IR analysis revealed functional groups involved in the binding mechanism of Tb are likely sulfate- and to a lesser extend hydroxyl-groups. The binding specificity of the isolated compounds was investigated with different metal solutions. Here, ions of the alkali and alkaline earth metals Na, K, Mg and Ca showed no competition for Tb-binding even at 10-fold excess concentration. Ions of the elements Co and Pb on the other hand replaced Tb at higher concentrations. Addition of the isolated compounds significantly reduced the precipitation of Eu at pH-values between 6.7 and 9.5, indicating that the interaction between the isolated chelators and Rare Earth Metals is stable even at high pH-values.

“…On the other hand, percentage of germination in Cicer arietinum treated with biotreated wastewater was significantly higher than those seeds treated with untreated CV solutions and were similar to control levels. Seeds exposed to biotreated wastewater exhibited the lowest values of phytotoxicity for Cicer arietinum seeds (Bhattacharya et al 2014).…”

Integral approach of sorption coupled with biodegradation for treatment of azo dye using Pseudomonas sp.: batch, toxicity, and artificial neural network

et al. 2018

The present study investigated the removal of azo dye (crystal violet) by adsorption (using a low-cost adsorbent fly ash), biodegradation (using bacterial species, sp.), and an integrated approach of sorption coupled with biodegradation (using fly ash immobilized with sp.) on a comparative scale. To ascertain immobilization of bacteria on fly ash, immobilized bacterial cells were characterized by energy-dispersive X-ray spectroscopy, scanning electron microscopy, Fourier-transform-infrared spectroscopy, and fluorescence microscopy. Batch studies were conducted for optimization of the process parameters for ensuring maximum dye removal. The optimum pH, temperature, and initial dye concentration for the highest percentage of dye removal were found to be pH 7, 37 °C, and 50 mg/L in all the three cases. Under optimized conditions, the highest percentage of dye removal was found to be 89.24, 79.64, and 99.04% for biodegradation, sorption, and integrated approach of sorption and biodegradation, respectively. Finally, phytotoxicity studies carried out with the treated water on seeds also carried proved that these processes and the adsorbent did not exert any toxic effects on the seeds. Artificial neural network modeling revealed a close interaction between theoretically predicted and experimentally obtained results and with an error of around 1.1%. Thus, this novel, environmentally sustainable and economically viable technique may be applied for effective removal of crystal violet from industrial wastewater.
