Project description:The anaerobic gut microbe Akkermansia muciniphila ATCC BAA-835 lives in the mucus layer where it is exposed to oxygen. To investigate how it survives the changing oxygen concentrations, we exposed a exponentially growing culture to oxygen. The experiment was performed in parallel fermentor systems. To one system we added 0.2l/h oxygen after the culture reached an OD of 0.1, while the other remained anaerobic. Samples were taken just before addition of oxygen, about 1h after and when the cell reached stationary phase.
Project description:Akkermansia muciniphila, a common member of the human gut microbiota, is considered to be a beneficial resident of the intestinal mucus layer. Surface-exposed molecules produced by this organism likely play important roles in colonization and communication with other microbes and the host, but the protein composition of the outer membrane has not been characterized thus far. Herein we identify A. muciniphila proteins after enrichment and fractionation of the outer membrane proteome of A. muciniphila.
Project description:We implemented transcriptomic analyses of blood and hippocampus of old mice treated with Akkermansia muciniphila Membrane Protein for 8 weeks.
Project description:Total RNA from ileum of three groups of mice are sequenced. The three groups are 1. wild type mice. 2. mice with IFNg gene knockout. 3. IFNg gene knockout mice after colonization of Akkermansia muciniphila
