Long-term fasting remodels gut microbial metabolism and host metabolism

Q. R. Ducarmon, F. Grundler, C. Giannopoulou, A Loumé, N. Karcher, M. Larralde, S. R. Romano, MR MacArthur, S. J. Mitchell, F. Wilhelmi de Toledo, G. Zeller, R. Mesnage

This study shows that long-term fasting changes gut microbial composition and function, as well as the serum metabolome, with significant shifts in microbial species and metabolite levels.

Large-scale computational analyses of gut microbial CAZyme repertoires enabled by Cayman

Q. R. Ducarmon, N. Karcher, H. L. P. Tytgat, O. Delannoy-Bruno, S. Pekel, F. Springer, C. Schudoma, G. Zeller

The paper develops Cayman, a CAZyme profiler, to analyze gut microbial CAZyme repertoires and finds differences in substrate preferences between Western and non-Western metagenomes and CRC patients.
