Arnulf Kletzin

PD Dr. Arnulf Kletzin is a lecturer at Technische Universität Darmstadt, specializing in sulfur biochemistry and microbial bioenergetics. His research focuses on sulfur-oxidizing and reducing enzymes, particularly sulfur oxygenases and persulfide dioxygenases, in extremophiles such as Acidianus ambivalens and Acidithiobacillus caldus. He investigates microbial sulfur metabolism in hydrothermal environments and its biotechnological applications in metal recovery from ores and electronic waste using cyanide-producing bacteria. His lab employs techniques like heterologous gene expression, protein characterization, and 3D structure analysis in collaboration with institutions in Portugal and Germany.
