Project description:Effect of Diet Composition on Change of Rumen Microbiome : Rumen Protozoa and Protozoa-associated Prokaryotes in vitro.
| PRJNA1098888 | ENA
Project description:The rumen harbors a complex mixture of archaea, bacteria, protozoa and fungi that efficiently breakdown plant biomass and its complex dietary carbohydrates into soluble sugars that can be fermented and subsequently converted into metabolites and nutrients utilized by the host animal. While rumen bacteria populations have been well documented, only a fraction of the rumen eukarya are taxonomically and functionally characterized, despite the recognition that they contribute to the cellulolytic phenotype of the rumen fauna. To investigate how anaerobic fungi actively engage in digestion of recalcitrant fiber that is resistant to the initial stages of rumination, we resolved genome-centric metaproteome and metatranscriptome datasets generated from switchgrass samples incubated in nylon bags within the rumen of cannulated dairy cows for 48 hours.

Project description:Protozoa comprise a major fraction of the microbial biomass in the rumen microbiome, of which the entodiniomorphs (order: Entodiniomorphida) and holotrichs (order: Vestibuliferida) are consistently observed to be dominant across a diverse genetic and geographical range of ruminant hosts. Despite the apparent core role that protozoal species exert, their major biological and metabolic contributions to rumen function remain largely undescribed in vivo. Here, we have leveraged (meta)genome27 centric metaproteomes from rumen fluid samples originating from both cattle and goats fed diets with varying inclusion levels of lipids and starch, to detail the specific metabolic niches that protozoa occupy in the context of their microbial co-habitants. Initial proteome estimations via total protein counts and label-free quantification highlight that entodiniomorph species Entodinium and Epidinium as well as the holotrichs Dasytricha and Isotricha comprises an extensive fraction of the total rumen metaproteome. Proteomic detection of protozoal metabolism such as hydrogenases (Dasytricha, Isotricha, Epidinium, Enoploplastron), carbohydrate-active enzymes (Epidinium, Diplodinium, Enoploplastron, Polyplastron), microbial predation (Entodinium) and volatile fatty acid production (Entodinium and Epidinium) was observed at increased levels in high methane-emitting animals. Despite certain protozoal species having well-established reputations for digesting starch, they were unexpectedly less detectable in low methane emitting- 37 animals fed high starch diets, which were instead dominated by propionate/succinate-producing bacterial populations suspected of being resistant to predation irrespective of host. Finally, we reaffirmed our abovementioned observations in geographically independent datasets, thus illuminating the substantial metabolic influence that under-explored eukaryotic populations have in the rumen, with greater implications for both digestion and methane metabolism.

Project description:<p>From an animal production and health perspective, our understanding of the metabolites in ruminant biofluids, particularly rumen fluid across different host species is poorly understood. Metabolomics is a powerful and sensitive approach for investigating low molecular weight metabolite profiles present in rumen biofluids. It can be used to identify potential roles of metabolites in the rumen microbiome and provide and understanding of host-level regulatory mechanisms associated with animal production. The rumen is a strictly anaerobic environment enriched with a complex community of bacteria, protozoa, fungi, archaea and bacteriophages. Here, we present a metabolomic dataset generated using hydrophilic interaction liquid chromatography (HILIC) and semi-polar (C18) chromatography methods coupled to high resolution mass spectrometry (MS), collected in both positive and negative ionization modes, of ovine rumen samples that were fractionated based on molecular weight (20 kDa, 8-10 kDa and 100 Da). This study highlights the potential of HILIC and C18 chromatography combined with non-targeted mass spectrometric methods to detect the polar and semi-polar metabolite species of the ruminal fluid metabolome.</p>
