Marta A. Polti, PhD, is an Independent Researcher at CONICET and a faculty member at the National University of Tucuman (Argentina), where she has taught Molecular Biology since 2003. She holds a degree in Biochemistry and a PhD in Biochemistry from the Universidad Nacional de Tucumán. Her research focuses on environmental biotechnology, particularly on the isolation, characterization, and genetic and metabolic analysis of actinobacteria capable of tolerating or degrading toxic metals, pesticides, petroleum-derived compounds, and emerging organic pollutants. Dr. Polti leads projects that integrate microbial ecology, molecular biology, and bioprocess development to design effective microbial systems for complex bioremediation scenarios. She has participated in collaborative international research initiatives with teams in Spain, France, Germany, and Algeria. Her recent work includes the study of microbial interactions, optimization of biodegradation processes, and the development of molecular tools for non-model Streptomyces species. She has authored numerous publications in environmental microbiology and biotechnology and actively contributes to advancing sustainable strategies for environmental restoration.
