Long-term fasting remodels gut microbial metabolism and host metabolism

Q. R. Ducarmon, F. Grundler, C. Giannopoulou, A. Loume, N. Karcher, M. Larralde, S. R. Romano, M. 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.
