Effluents from the leather tanning industry contain diverse pollutants, including hazardous heavy metals, posing threats to public health and surrounding environment. Indigenous bacterial isolates can represent an eco-friendly approach for tannery wastewater treatment; however, phenotypic characterization is necessary determine whether these strains are suitable bioremediation. In present study, we analyzed seven new Enterococcus faecium two Bacillus subtillis isolated effluents Southern Tunisian Tannery (ESTT). We evaluated features beneficial bioremediation, biofilm formation, hydrophobicity, exoenzyme activities. Additionally, examined characteristics naturally occurring in environmental bacteria but less desirable selected such as antibiotic resistances pathogenicity indicators. The observed phenotypes were then compared with whole-genome analysis. production slime-producing bacteria, B. licheniformis RLT6, E. RLT8. Hydrophobicity of RLT1, RLT5, RLT8, RLT9, well RLT6 correlated positively increasing ESTT concentration. Exoenzyme activities detected RLT2, RLT4, RLT7, RLT6. As anticipated, all exhibited common antibiotics hemolysis, which widespread nature do not hinder their application Importantly, none pathogenic hypermucoviscosity phenotype. To best our knowledge, this first report consolidating concurrently, providing a complete overview suitability IMPORTANCE: study evaluates bioremediation potential (ESTT), pose integrity. analysis primarily examines traits crucial activities, related metal resistance, resistances. Several found have high exhibit only commonly nature, ensuring remains uncompromised. results exhaustive contrasted whole genome sequences nine strains, underscoring appropriateness interventions treatment.

In the recent era, increasing persistence of hazardous contaminants is badly affecting globe in many ways. Due to high environmental contamination, almost every second species on earth facing worst issue their survival. Advances newer remediation approaches may help enhance bioremediation's quality, while conventional procedures have failed remove compounds from environment. Chemical and physical waste cleanup been used current circumstances; however, these methods are costly harmful Thus, there has a rise use bioremediation due an increase which led development genetically engineered microbes (GEMs). It safer more cost-effective microorganisms rather than alternative methods. GEMs created by introducing stronger protein into bacteria through biotechnology or genetic engineering desired trait. Biodegradation oil spills, halobenzoates naphthalenes, toluenes, trichloroethylene, octanes, xylenes etc. accomplished using such bacteria, fungus, algae. Biotechnologically induced powerful naturally occurring ones degrade faster because they can quickly adapt new pollutants encounter co-metabolize. Genetic worthy process that will benefit environment ultimately health our people.

Industrial development has enhanced the release into environment of large quantities chemical compounds with high toxicity and limited prospects degradation. The pollution soil water xenobiotic chemicals become a major ecological issue; therefore, innovative treatment technologies need to be explored. Fungal bioremediation is promising technology exploiting their metabolic potential remove or lower concentrations xenobiotics. In particular, white rot fungi (WRF) are unique microorganisms that show capacities degrade wide range toxic such as synthetic dyes, chlorophenols, polychlorinated biphenyls, organophosphate pesticides, explosives polycyclic aromatic hydrocarbons (PAHs). this review, we address main classes enzymes involved in fungal degradation organic pollutants, mechanisms used by these suitability biomass extracellular for bioremediation. We also exemplify role several degrading pollutants PAHs emerging pharmaceuticals perfluoroalkyl/polyfluoroalkyl substances (PFASs). Finally, discuss existing current limitations using WRF polluted environments future strategies improve biodegradation processes.

Abstract Azo dyes constitute 60–70% of commercially used and are complex, carcinogenic, mutagenic pollutants that negatively impact soil composition, water bodies, flora, fauna. Conventional azo dye degradation techniques have drawbacks such as high production maintenance costs, use hazardous chemicals, membrane clogging, sludge generation. Constructed Wetland—Microbial Fuel Cells (CW-MFCs) offer a promising sustainable approach for the bio-electrodegradation from textile wastewater. CW-MFCs harness phytodegradation capabilities wetland plants like Azolla, hyacinth, Ipomoea, along with microalgae Nostoc, Oscillatoria, Chlorella, Anabaena, to break down into aromatic amines. These intermediates then reduced CO2 H2O by in fuel cells, while simultaneously generating electricity. advantages including low cost, sustainability, renewable energy. The valorization resulting algal plant biomass further enhances sustainability this approach, it can be biofuel production, nutraceuticals, pharmaceuticals, bio-composting. Implementing tertiary treatment step industries aligns circular economy concept contributes achieving several Sustainable Development Goals (SDGs).
