The results confirmed the efficient elimination of S. aureus simultaneously with a significant reductionof the physicochemical values, with constant efficiency up to 30 min. Scanning electron microscopy images confirm the removal of S. aureus on the effluent surface and sludge. Thus, this study was able to present a natural coagulant capable of removebacteria and adjust the quality levels of the effluentafter 10 min of sedimentation, making this biotechnological innovation highly applicable to ETP.Monitoring water quality is a fundamental process to ensure proper anthropogenic usage and environmental protection of this resource. This study collected monthly measurements of 9 parameters (pH, Temperature, BOD, Total Solids, Thermotolerant Coliforms, Dissolved Oxygen, Total Nitrogen and Total Phosphorus) in 5 sampling stations along the Marrecas water stream, during a 1-year period. Temporal andseasonalvariationswereanalyzedandinterpretedforeachelement,explaininghowspecificgeographical and anthropogenic factors affected the water body. Principal Component Analysis (PCA) was applied to evaluate each element's correlation and to reduce the number of parameters, easing the assessment of waterqualityforeachlocation.Resultswerefollowedbythecreationofanimprovedindexfortheregion, that could better estimate the quality of water, only considering 4 of the original parameters. It was also recognized that each water body possesses several subtleties that impact on how its water quality should be measuredandindexedintoasinglevalue,whichvalidatesthecaseforthecreationofregionalWQI's.Three-dimensional (3D) hydrogel systems integrating different types of stem cells and scaffolding biomaterials have an important application in tissue engineering. The biomimetic hydrogels that pattern cell suspensions within 3D configurations of biomaterial networks allo
