Section for Microbiology and Biofilms

«The smallest creatures are great and where and how they live, is fascinating.»

Prof. Dr. Walter Krebs, Head of Section

Microorganisms such as bacteria, protozoa as well as various algae and fungi can establish themselves on almost all surfaces and form thin structured habitats = biofilms. Protected by a matrix of gel-like mucus, which consists of extracellular polymers, the biofilm organisms can form diverse, powerful and robust communities.

We deal mainly with microbial biofilms, which can cause serious problems on certain surfaces. Examples include infections in the body, on implants and in medical devices, the destruction of building materials, machinery and materials, the corrosion and clogging of piping systems, and the reduction of heat transfer in heat exchangers.

The control of pathogenic microorganisms and biofilms is a additional challenge, especially in the context of increasing resistance.

Areas of expertise

In collaboration with the industry and our project partners, we develop and check case-specific solutions for challenges such as how existing biofilms can be tackled and their formation controlled and reduced.

With the help of existing test systems as well as customer-specific modifications and developments, we can observe and analyze biofilm formation.

The analysis of biofilms is carried out by means of traditional microbiology, biochemistry and chemistry methods such as:

In respect of microbiology, the following are also available:
