Dr. Antoine Tamsa Arfao’s research focuses on water and environmental microbiology with a strong emphasis on the ecological dynamics of aquatic systems and sustainable water management. His work investigates the bacteriological and physicochemical quality of diverse aquatic ecosystems, assessing how environmental factors and pollutants influence microbial communities and ecosystem health. A significant part of his research explores the impact of antibiotics and other physicochemical variables on bacterial populations, contributing to understanding microbial resistance mechanisms in aquatic environments. Additionally, his studies advance the development and optimization of water treatment processes aimed at effective disinfection and decontamination. Through experimental and analytical approaches, his research contributes to identifying environmental risks, improving water quality assessment methods, and designing innovative biotechnological solutions for maintaining ecosystem integrity. His contributions help bridge fundamental microbiological insights with applied environmental management, promoting strategies for cleaner and safer aquatic resources.
