Project description:2,5-furan dicarboxylic acid (FDCA) is the top-12 value-added chemicals derived from biomass that may serve as a 'green' substitute for terephthalate acid (TPA) in polyesters. FDCA can be synthesized chemically from 5-(hydroxymethyl) furfural (HMF), which is produced from fructose or glucose. To investigate impact of the production chain of FDCA on terrestrial ecosystem and unravel molecular pathways invoked and the biological process affected in the animal, a microarray analysis was applied to measure the transcriptome-wide response in soil invertebrates Folsomia candida. Microarrays examined transcriptional changes at EC50 concentrations of FDCA, HMF and TPA spiked in sterilized LUFA 2.2 soils. The results indicated FDCA and TPA caused no significant change in gene expression, which may due to the low chemical water solubility leading to slow uptake by the animal from the pore water after. A substantial number of genes were significantly regulated in F. candida after exposure to HMF. Gene Ontology analysis showed many biological process were significantly affected, such as nucleic acid metabolism, transcriptional metabolic process, cell developmental process and oxidation-reduction process. Transcriptional profile also indicated HMF can be biotransformed by F. candida into SMF which is genotoxic and mutagenic. The current research shows that environmental risk of the FDCA production chain from biomass is not due to the final product but to the intermediate HMF.

Project description:Investigation of microbial community composition in mouse models using an intestinal epithial-specific and inducible VilCreERT2-mediated conditional knockout of Jup under basal conditions and in acute dextran-sodium sulfate (DSS)-induced colitis We investigated the gut microbiome composition in a dextran sulfate sodium (DSS) colitis model using Jupfl/fl and iVilCreERT2Jupfl/fl mice. Fecal samples were collected after DSS treatment, and 16S rRNA sequencing was employed to analyze microbial communities. Our findings revealed no significant differences in microbial profiles between Jupfl/fl and iVilCreERT2Jupfl/fl under DSS treatment.

Project description:Soil transplant serves as a proxy to simulate climate change in realistic climate regimes. Here, we assessed the effects of climate warming and cooling on soil microbial communities, which are key drivers in Earth’s biogeochemical cycles, four years after soil transplant over large transects from northern (N site) to central (NC site) and southern China (NS site) and vice versa. Four years after soil transplant, soil nitrogen components, microbial biomass, community phylogenetic and functional structures were altered. Microbial functional diversity, measured by a metagenomic tool named GeoChip, and phylogenetic diversity are increased with temperature, while microbial biomass were similar or decreased. Nevertheless, the effects of climate change was overridden by maize cropping, underscoring the need to disentangle them in research. Mantel tests and canonical correspondence analysis (CCA) demonstrated that vegetation, climatic factors (e.g., temperature and precipitation), soil nitrogen components and CO2 efflux were significantly correlated to the microbial community composition. Further investigation unveiled strong correlations between carbon cycling genes and CO2 efflux in bare soil but not cropped soil, and between nitrogen cycling genes and nitrification, which provides mechanistic understanding of these microbe-mediated processes and empowers an interesting possibility of incorporating bacterial gene abundance in greenhouse gas emission modeling.

Project description:Tibet is one of the most threatened regions by climate warming, thus understanding how its microbial communities function may be of high importance for predicting microbial responses to climate changes. Here, we report a study to profile soil microbial structural genes, which infers functional roles of microbial communities, along four sites/elevations of a Tibetan mountainous grassland, aiming to explore potential microbial responses to climate changes via a strategy of space-for-time substitution. Using a microarray-based metagenomics tool named GeoChip 4.0, we showed that microbial communities were distinct for most but not all of the sites. Substantial variations were apparent in stress, N and C cycling genes, but they were in line with the functional roles of these genes. Cold shock genes were more abundant at higher elevations. Also, gdh converting ammonium into urea was more abundant at higher elevations while ureC converting urea into ammonium was less abundant, which was consistent with soil ammonium contents. Significant correlations were observed between N-cycling genes (ureC, gdh and amoA) and nitrous oxide flux, suggesting that they contributed to community metabolism. Lastly, we found by CCA, Mantel tests and the similarity tests that soil pH, temperature, NH4+–N and vegetation diversity accounted for the majority (81.4%) of microbial community variations, suggesting that these four attributes were major factors affecting soil microbial communities. Based on these observations, we predict that climate changes in the Tibetan grasslands are very likely to change soil microbial community functional structure, with particular impacts on microbial N cycling genes and consequently microbe-mediated soil N dynamics.
