Sabrina Hedrich

Prof. Dr. Sabrina Hedrich serves as Professor and Head of the Institute of Biosciences at Technische Universität Bergakademie Freiberg within the Faculty of Resources. She leads the Microbiology and Biohydrometallurgy research group, directing cutting-edge investigations into microbial processes for sustainable metal recovery and environmental remediation. Her work bridges fundamental microbiology with industrial applications in resource extraction.

Her research centers on extremophilic microorganisms, particularly acidophiles capable of iron/sulfur metabolism and sulfate reduction under extreme conditions. Key focus areas include bioleaching of primary ores and secondary resources (e-waste, mine tailings), selective metal recovery through biosorption/biomineralization, and microbial community dynamics in acidic environments. This work integrates physiology, taxonomy, and ecology to develop biotechnological solutions for circular economy challenges in mining and metallurgy.

Analysis of her recent publications reveals intensifying research on hydrodynamic-biogeochemical controls in legacy mine waters, bioleaching of battery materials (lithium iron phosphate), and rare earth element recovery. Her work increasingly emphasizes process engineering integration (membrane filtration, bioreactor design) and molecular approaches to difficult-to-express proteins, demonstrating evolution from fundamental microbial studies toward applied industrial solutions.

While specific student lists and grant details were not provided, her leadership of a major research group implies active supervision of doctoral candidates and postdoctoral researchers in biohydrometallurgy. Her work likely involves collaborative projects with mining industries and environmental technology firms focused on sustainable resource recovery.

Prof. Hedrich directs the Microbiology and Biohydrometallurgy laboratory facilities, which specialize in culturing acidophilic microorganisms, conducting bioleaching experiments with metal sulfides and industrial wastes, and developing bioreactor systems for metal recovery. The group maintains advanced capabilities in microbial community analysis, protein expression, and process optimization for industrial applications.
