Bacterial cells produce a variety of exopolysaccharide (EPS) throughout their life cycle. EPS plays crucial role in the formation biofilms and control environmental processes microbial communities. The bacterial community benefits from several ways, including nutrient compartmentation storage, stress resistance synergism. generation by consortium-associated bacteria, which involves microorganisms, is versatile efficient for use industrial processes, such as biotechnology pollution degradation. qualitative quantitative chemical characteristics consortium's are mostly determined type culture utilized, type, temperature, pH. main goal study was to find out how biosynthesis works consortium culture. To achieve maximum regeneration, pH, carbon, nitrogen sources were optimized. A three strains i.e. Klebsiella pneumonia strain, Pseudomonas aeruginosa strain Burkholderia cepacian that distinguished capacity developed part study. total production detected after 8 days incubation at pH 7.5 (15.5 g/L) temperature 35 °C (12.60 g/L). optimum identified 17.84 g/L 21.07 when ammonium sulfate glucose employed carbon supplements, respectively. protein concentration 3067 µg/mL, more than carbohydrate (263.10 µg/mL) DNA (7.60 content. protein/carbohydrate ratio present 11.65, much higher prior investigations. FTIR analysis confirmed functional groups carbohydrates, proteins, lipids DNA, viz., CO, COOH, NH, OH, CH OCH3. study's findings revealed enhancing molecules lowering biofilm-related infections improving efficacy antimicrobial treatments wastewater.

Phytoremediation is an economical, environmentally friendly and effective technology that uses plants to treat wastewater. This research focuses on phytoremediation of wastewater industrial pharmaceutical. Certain fresh plant species, such as Lemna minor, Salvinia minima, Ipomoea aquatica Centella asiatica, have been shown decontaminate environments. For example, these helped reduce total suspended solids (TSS) from 50.8% 85.6%, ammonia nitrogen (NH3-N) 79.1% 97.3% chemical oxygen demand (COD) 36.46% 82% in The exact results depend the type its operating time. In addition, microalgae Chlorella pyrenoidosa Scenedesmus almeriensis be highly removing heavy metals cadmium (57.14% just 3 hours) arsenic (40.7% hours). conclusion, a promising approach water treatment sector, particularly for pharmaceutical which heavily contaminated with complex toxic substances.

Pseudomonas aeruginosa, a Gram-negative, motile bacterium, may cause significant infections in both community and hospital settings, leading to substantial morbidity mortality. This opportunistic pathogen can thrive various environments, making it public health concern worldwide. P. aeruginosa’s genomic pool is highly dynamic diverse, with pan-genome size ranging from 5.5 7.76 Mbp. versatility arises its ability acquire genes through horizontal gene transfer (HGT) via different genetic elements (GEs), such as mobile (MGEs). These MGEs, collectively known the mobilome, facilitate spread of encoding resistance antimicrobials (ARGs), heavy metals (HMRGs), virulence (VGs), metabolic functions (MGs). Of particular are acquired carbapenemase (ACGs) other β-lactamase genes, classes A, B [metallo-β-lactamases (MBLs)], D carbapenemases, which lead increased antimicrobial resistance. review emphasizes importance mobilome understanding aeruginosa.
