Evaluating scaling of capillary photo-biofilm reactors for high cell density cultivation of mixed trophies artificial microbial consortia
Capillary biofilm reactors (CBRs) are attractive for growing photoautotrophic bacteria as they allow high cell-density cultivation. Here, we evaluated the CBR system’s suitability to grow an artificial consortium composed of Synechocystis sp. PCC 6803 and Pseudomonas sp. VBL120. The impact of reactor material, flow rate, pH, O2, and medium composition…
Entropic repulsion of cholesterol-containing layers counteracts bioadhesion
Based on a cooperation with colleagues from Dresden, we newly published a paper in Nature on a new mechanism counteracting bioadhesion by entropic repulsion of orientational fluctuations in cholesterol multilayers. Our results not only reveal this new mechanism of entropic repulsion to be relevant in the surface properties of Collembola,…
Achieving sustainable feed proteins with “REPLACER”
In the REPLACER project, researchers are developing so-called hybrid living materials. The focus is on producing microbial proteins with a low carbon footprint, high acceptance and affordable costs – by using greenhouse gases. The long-term goal: sustainable production of feed proteins. An example of applied research with great transfer potential….
