“…The authors have already reported that, under stress conditions, the percentage of stress-sensitive proteins and pesticide-degrading proteins was high, making the organism more comfortable [ 41 ]. Similarly, in another study, genomic, transcriptome, and proteomic studies of B. cereus GW-01 during β-cypermethrin and its metabolite degradation revealed that α/β- hydrolase and a cytochrome aa3 quinol oxidase were responsible for β-cypermethrin and 3-phenoxy benzoic acid (3-PBA) degradation, respectively [ 42 ].…”

“…The current study confirmed a biofilm of mixed culture (D6) has strong potential for MG degradation. However, information regarding the uses of a mixed culture biofilm to degrade and detoxify the CR is very limited in the literature [42,64,65]. To the best of our knowledge, biofilms of an isolate L. sphaericus capable of degrading CR are little documented in the literature.…”

“…The supernatant of the treated samples and control was carefully collected and biodegraded metabolites/residues in the supernatant were subjected to FTIR analysis [ 42 ]. FTIR of the samples containing the biodegraded CYP, IMI, MG and CR was carried out in the IR range of 500–4500 cm −1 to identify the stretching of bonds in the test pesticides and dyes after biodegradation [ 9 ].…”

Overuse of pesticides in agricultural soil and dye-polluted effluents severely contaminates the environment and is toxic to animals and humans making their removal from the environment essential. The present study aimed to assess the biodegradation of pesticides (cypermethrin (CYP) and imidacloprid (IMI)), and dyes (malachite green (MG) and Congo red (CR)) using biofilms of bacteria isolated from pesticide-contaminated soil and dye effluents. Biofilms of indigenous bacteria, i.e., Bacillus thuringiensis 2A (OP554568), Enterobacter hormaechei 4A (OP723332), Bacillus sp. 5A (OP586601), and Bacillus cereus 6B (OP586602) individually and in mixed culture were tested against CYP and IMI. Biofilms of indigenous bacteria i.e., Lysinibacillus sphaericus AF1 (OP589134), Bacillus sp. CF3 (OP589135) and Bacillus sp. DF4 (OP589136) individually and in mixed culture were tested for their ability to degrade dyes. The biofilm of a mixed culture of B. thuringiensis + Bacillus sp. (P7) showed 46.2% degradation of CYP compared to the biofilm of a mixed culture of B. thuringiensis + E. hormaechei + Bacillus sp. + B. cereus (P11), which showed significantly high degradation (70.0%) of IMI. Regarding dye biodegradation, a mixed culture biofilm of Bacillus sp. + Bacillus sp. (D6) showed 86.76% degradation of MG, which was significantly high compared to a mixed culture biofilm of L. sphaericus + Bacillus sp. (D4) that degraded only 30.78% of CR. UV–VIS spectroscopy revealed major peaks at 224 nm, 263 nm, 581 nm and 436 nm for CYP, IMI, MG and CR, respectively, which completely disappeared after treatment with bacterial biofilms. Fourier transform infrared (FTIR) analysis showed the appearance of new peaks in degraded metabolites and disappearance of a peak in the control spectrum after biofilm treatment. Thin layer chromatography (TLC) analysis also confirmed the degradation of CYP, IMI, MG and CR into several metabolites compared to the control. The present study demonstrates the biodegradation potential of biofilm-forming bacteria isolated from pesticide-polluted soil and dye effluents against pesticides and dyes. This is the first report demonstrating biofilm-mediated bio-degradation of CYP, IMI, MG and CR utilizing soil and effluent bacterial flora from Multan and Sheikhupura, Punjab, Pakistan.

“…Due to the restricted amount of water that is readily available, this priceless resource is gradually becoming contaminated as a result of intensive human and industrial activity. [1] Batteries, power stations, food & beverages, steel and iron manufacturing, industrial plants, mines, nuclear energy, oil and gas, organic chemicals manufacturing, petroleum refineries and petrochemical products, pulp & paper production, blast furnaces, textile factories, large-scale oil pollutants, sewage treatment, and timber restoration are all sources of contaminated water. However, a review of the literature demonstrated that the textile sector consumes the most water and, discharges among other industries.…”

Dye Decolorization by Rhodococcus ruber Strain TES III Isolated from Textile Effluent Wastewater Contaminated Soil

Textile industries monopolize the use of synthetic and natural colors, claiming they are safe for the environment. These dyes have disastrous repercussions when released into the terrestrial and aquatic environment. The main purpose of the study was to isolate a biosurfactant‐producing bacterium from textile effluent‐contaminated soil and study its potential for dye degradation. Biosurfactant was extracted from Rhodococcus ruber strain TES III, a bacterium isolated from textile water contaminated soil. This biosurfactant‐producing bacterium was capable of decolorizing both synthetic dyes like methyl orange, methylene blue, and natural dyes like Indigo. There was a 2‐fold increase in methyl orange degradation after 48 hours, a 1‐fold increase in methylene blue degradation, and a 4.13‐fold increase in indigo dye degradation. Based on the foregoing data, we conclude that the biosurfactant‐producing bacteria Rhodococcus ruber strain TES III has a high potential for dye degradation and hence can be used in wastewater treatment of textile industries.
