(Photo)biofilm technologies for productive biocatalysis


In biocatalysis the traditional bottlenecks like inefficient stability, toxicity problems, and difficulties in running continuous processes are still prevailing. In the recent years the exploitation of surface attached microbes termed ‘biofilms’ has received increasing attention as these microbial communities have the potential to counteract such  shortfalls[1]. Furthermore, the biofilm concept has been extended to photo(auto)trophic organisms, which utilize light as energy and carbon dioxide as carbon source[2]. Especially in the context of climate change and carbon dioxide budgets this research has become increasingly relevant. Here, the current state-of-the-art in biofilm engineering will be presented with special emphasis on photo-active biofilm consortia.
