Fecal transplants in zebrafish reveal effects of diet and microbiome on intestinal gene expression and enzyme activity.

Project description:This study examined the functional response of a host (zebrafish) to implantation of a conspecific or allospecific (goldfish) gastrointestinal (GIT) microbiome followed by diet manipulation and the repercussions of these manipulations on host GIT physiology. Implantation of a native zebrafish biome successfully reintroduced wildtype (WT) communities with the exception of several rare, phylogenetically distant species. Implantation of a foreign goldfish biome created communities that were distinct from WT, suggesting that the seeding community created substantial differences from the native host communities. A mismatched ?natural? diet and an implanted allospecific biome enriched for rarer and more phylogenetically diverse bacteria. Transcriptional changes within the GIT clustered in relationship to biome treatments, mirroring clustering of biome implants. Implantation of an allospecific biome along with an altered diet markedly down-regulated approximately 70% of the transcripts involved in cholesterol biosynthesis, while tissue content analysis revealed an increase in total tissue cholesterol. Furthermore, transcripts involved in lipogenesis pathways were significantly downregulated and correlated with a striking decrease in intestinal lipase activity driven by both biome and diet. Glucose-6P dehydrogenase (G6PD) activities increased during dietary manipulations regardless of biome, while the allospecific biome down-regulated transcripts involved in gluconeogenesis and altered glucokinase (GK) and hexokinase (HK) activities regardless of diet. However, growth rates did not reveal an impact of these responses. Adult zebrafish are unable to reform proportional representation within bacterial communities following transplantation of an allospecific biome resulting in transcriptional and enzymatic alterations for lipid and carbohydrate metabolism that did not affect overall animal homeostasis.

Functional characterization of microbial communities from glacial ecosystems

Project description:Glaciers are populated by a large number of microorganisms including bacteria, archaea and microeukaryotes. Several factors such as solar radiation, nutrient availability and water content greatly determine the diversity and abundance of these microbial populations, the type of metabolism and the biogeochemical cycles. In order to study their metabolic potentials, samples of glacial ice were taken from several glacial ecosystems. Microorganisms were analyzed by a polyphasic approach that combines a set of -omic techniques: 16S rRNA sequencing, culturomics and metaproteomics. This combination provides key information about diversity and functions of microbial populations, especially in rare habitats. Several whole essential proteins and enzymes related to metabolism and energy production, recombination and translation were found that demonstrate the existence of cellular activity at subzero temperatures.

Microbial and Functional Diversity within the Phyllosphere of Espeletia sp. in Andean High Mountain Ecosystems

Project description:Functional profiles predicted based on taxonomic affiliations differed from those obtained by GeoChip microarray analysis, which separated community functional capacity based on plant location. The identified metabolic pathways provided insight regarding microbial strategies for colonization and survival in these ecosystems.
