Climate change, inadequate possessions, and land degradation all pose obstacles to modern agriculture. In the current scenario, agriculture industry is mainly dependent on use of chemical-based pesticides fertilizers that impact soil health crop productivity. Moreover, water scarcity leads farmers in drastically affected regions heavy metal-enriched sources originating from industrial for field crops irrigation. Soil pollutants can be carried into human body via dust water, creating negative effects varying simple symptoms, e.g., nausea diarrhea reaching death critical cases. Thus, clean contaminants, improve fertility agricultural production, alternatives chemical must developed. Therefore, using beneficial microbes found plant-associated microorganisms offers an effective strategy alleviate some these challenges, improving fertility, yield, protecting plants stress conditions. Through synergistic interactions, synthetic consortium seeks stability microbial communities. this review, consortia their potential were discussed. Further, engineering new was suggested as approach concept environmental bioremediation contaminants.

This study reports on the antibacterial efficacy of both TiO2 and TiO2/Cu nanoparticles prepared through sol–gel method. The materials were characterized by scanning electron microscopy (SEM), transmission (TEM), energy-dispersive X-ray spectroscopy (EDS), diffraction (XRD), Fourier-transform infrared (FTIR), Raman spectroscopy, photoelectron (XPS), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET) analysis. SEM TEM showed spherical morphology nanoparticles, while EDX XPS confirmed incorporation Cu into nanoparticles. XRD formation tetragonal anatase phase FTIR revealed functional groups linked to doped thermal stability was found be lower than pure TiO2. Moreover, notably effective against Bacillus subtilis (B. subtilis) andEscherichia coli(E. coli); however, addition did not have any effect activity probably due weight content in composites. Interestingly, efficiency determined 90 80% B. E. coli, respectively.
