Hans-Curt Flemming „How biofilms organize their life – the role of the EPS matrix“

HIPS Talk

  • Überblick

    Summary

    Biofilms are the oldest and most abundant form of life on Earth. In biofilms, microorganisms live in their self-produced matrix of hydrated extracellular polymeric substances (EPS), which determine the immediate environment and the conditions of life for biofilm organisms. EPS are mainly polysaccharides, proteins, nucleic acids and lipids. They provide the mechanical stability of biofilms, mediate their adhesion to surfaces and provide a cohesive, three-dimensional polymer network interconnecting and immobilizing biofilm cells. This leads to the development of microbial communities of high cell density, allowing for intense cell-cell communication and orchestrating metabolic performance. The biofilm matrix acts as an external digestion system, keeping extracellular enzymes close to biofilm cells, capable of metabolising dissolved, colloidal and solid biopolymers. Due to the physiological activity of biofilm organisms, gradients develop, creating different habitats which support high biodiversity. The EPS matrix is a key to understand the biofilm mode of life.

    CV

    Hans-Curt Flemming was born 1947 at the Lake Constance, between Germany, Switzerland and Austria. He studied Chemistry in Freiburg and Stuttgart and did his Ph. D. at the Max Planck Institute for Immunology in Freiburg on the biosynthesis of bacterial exopolysaccharides. At the University of Stuttgart, he implemented the Biofilm Research group between 1986 and 1994, when he went to the University of Munich to establish the Biotechnology group. In 1996 he got a position as chair for Aquatic Microbiology at the University of Duisburg-Essen. He also is a member of the Board of Directors of the IWW Water Centre in Mülheim. In 2000, he was one of the founders of the interdisciplinary curriculum “Water Science” which includes chemistry, analytics and microbiology of water. His main research focus is microbial biofilms. Since 2012, he is a visiting professor at the Nanyang Technical University of Singapore, active in the Singapore Center for Life Science Engineering. He has published about 300 scientific papers and 10 books. Currently, he is the chairman of the BioCluster, a joint activity of the International Water Association (IWA) and the International Society of Microbial Ecology (ISME).
