Pseudomonas aeruginosa is an opportunistic pathogen causing acute and chronic infections, especially in immunocompromised patients. Its remarkable adaptability resistance to various antimicrobial treatments make it difficult eradicate. persistence enabled by its ability form a biofilm. Biofilm community of sessile micro-organisms self-produced extracellular matrix, which forms scaffold facilitating cohesion, cell attachment, micro- macro-colony formation. This lifestyle provides protection against environmental stresses, the immune system, treatments, confers capacity for colonization long-term persistence, often characterizing infections. In this review, we retrace events life cycle P. biofilm, from surface perception/contact spreading. We focus on importance appendages, mechanical constraints, kinetics matrix component production each step biofilm cycle.

Wastewater Treatment Plants (WWTPs) encompass a range of processes from preliminary to advanced stages. Conventional treatments are increasingly inadequate for handling emergent pollutants, particularly organic compounds with carcinogenic potential that pose risks aquifers. Recent advancements prioritize integrating Advanced Oxidation Processes (AOPs) and adsorbents conventional methods effectively retain pollutants enhance mineralization. There is growing preference non-chemical or minimally chemical approaches. Innovations such as combining ozone other biological photo-sono-assisted methods, alongside AOPs adsorbents, promising. These approaches leverage catalyst-assisted reactions optimize oxidation efficiency. This review aims provide holistic perspective on WWTP processes, spanning wastewater intake the production potable water, highlighting key technologies, operational challenges, future trends. The focus advancing sustainable practices enhancing treatment efficacy safeguard water quality address evolving environmental concerns effectively.

ABSTRACT The search for life elsewhere in the universe has remained one of main goals astrobiological exploration. In this quest, extreme environments on Earth have served as analogs to study potential habitability Mars and icy moons, which include but are not limited hydrothermal vent systems, acid lakes, deserts, polar ice, among others. Within various forms that manifests, biofilms constitute most widespread phenotypes ubiquitous environments. Biofilms structured communities microorganisms enclosed a matrix extracellular polymeric substances (EPS) protect against unfavorable dynamic conditions. These concentrated structures their associated chemistry may serve unique persistent signatures processes aid detection.
