TL;DR: The diurnal rhythmicity of the gut microbiota; its crucial role in host physiology, health, and metabolism; and the crosstalk between the gut microbial rhythmicity and host circadian rhythm are discussed.

TL;DR: In this article, the authors investigated the responses of the microbiome and metabolome induced by time-restricted feeding based on a growing-pig model, and found that although the overall microbial composition in the colon was not changed, TRF induced the gradient changes of the nutrients and metabolites which were correlated with certain microbial genera including Lactobacillus, Eubacterium_ruminantium group, S. coprostanoligenes group, Prevotella 1 and Clostridium sensu sticto 1.

TL;DR: In this paper , the effects of pectin on gut microbial taxa and functions, as well as its interactions with altered environmental features were investigated, and it was shown that a PEC-enriched diet decreased the abundances of fungal keystone taxa (e.g., amino acid-producing Kazachstania spp.) and their genes involved in oxidative phosphorylation, while it increased the abundance of sulfate-reducing Desulfovibrio spp., and methane-producing Methanobrevibacter spp.

TL;DR: The study found that the feed intake, nutrient substrates, microbiota and metabolites in the colon underwent asynchronous oscillation within a day, and validated the evolution of gut microbes under different carbohydrate and protein combinations by using an in vitro fermentation experiment.
