“…However, in other studies, a range of pH from to 9-10 was determined to be the optimal for dye decolorization using Bacillus sp. strain CH12 and Exiguobacterium profundum strain CMR2 [48,49]. However, under an acidic pH, the H + ions may inhibit the dye cations, causing a reduction in the decolorization performance [3].…”

“…This clearly indicates that the efficiency of decolorization greatly varies according to different carbon and nitrogen sources, which strongly depends on the demand of various bacterial strains. Starch was the optimal carbon source for bacterial strain Exiguobacterium profundum strain CMR2 to maximize the removal efficiency of Reactive Blue EFAF, which reached 82% [49]. Nevertheless, the maximum decolorization of MB dye was 98.11% in the presence of glucose by Bacillus albus MW407057 [42].…”

Biodegradation of Methylene Blue Using a Novel Lignin Peroxidase Enzyme Producing Bacteria, Named Bacillus sp. React3, as a Promising Candidate for Dye-Contaminated Wastewater Treatment

The emission of methylene blue (MB) from common industries causes risks to human health by making clean drinking water unavailable and hampering environmental safety. A biological approach offering a more cost-efficient and sustainable alternative solution has been studied and demonstrated to be significantly effective for the removal of MB using promising microbial isolates. Therefore, this study targeted bacterial candidates, namely Bacillus sp. React3, isolated from soil with the potential to decolorize MB. The phenogenic identification of strain React3 was performed by 16S rRNA sequencing, showing a similarity of 98.86% to Bacillus velezensis CR-502T. The ability of this bacterial strain to decolorize MB was proven through both the lignin peroxidase efficiency and accumulation in the biomass of the living cells. MB removal was determined by the reduction in the maximum absorption at a wavelength of 665 nm, which was observed to be up to 99.5% after 48 h of incubation. The optimal conditions for the MB degradation of strain React3 were pH 7, 35 °C, static, 4% inoculum, and 1000 mg/L of MB, with tryptone as a carbon source and yeast extract as a nitrogen source.

“…Therefore, it is necessary to develop an effective, economical and environmental friendly method for exclusion of toxic dyes completely from the textile wastewater [8]. Several conventional methods are available for textile wastewater treatment such as physical, chemical [9,10] and some engineered techniques including adsorption [11], electrolysis [12], oxidation [13] and photo-ionization [14].…”

The study was envisioned to evaluate the decolorization of Reactive Blue 160 (RB160) dye by using indigenous microbes. Contaminated soil from textile dye industry was collected from Noyyal river basin, Tamil Nadu, India. Potential dye degrading bacterial strain was recognized as Bacillus firmus by 16SrRNA gene sequencing analysis. RB160 dye (500 μg/ml) was effectively degraded by B. firmus and toxicological analyses were performed with RB160 and their degraded product. Phytotoxicity revealed that degraded product of RB160 into non-toxic nature by B. firms. Toxicity assays were carried out on root cells of Allium cepa and human skin cell line (CRL 1474). Toxicity analysis of A. cepa and cell line signifies that dye exerts toxic cause on the root cells and IC50 values of RB160 showed toxic to human skin cell lines, while degradation products of the dye are moderately less in toxic. Zebrafish embryo toxicity also evaluated by RB160 and degraded product on phenotypic deformation, survival, hatching and heartbeat rate. However, RB160 with concentration of 500 μg/ml decrease in the survival, hatching, heartbeat rate and induced phenotypic alterations. In which, degraded products exhibited significant development in zebrafish embryos as compared to dye. Based on the studies effects of RB160 and capability of B. firmus can effectively degrade RB160, and their degraded products were harmless to the environments and aquatic system.
