Project description:Sulfate-reducing bacteria (SRB) are ubiquitously distributed across various biospheres and play key roles in global sulfur and carbon cycles. However, few deep-sea SRB have been cultivated and studied in situ, limiting our understanding of the true metabolism of SRB in the deep biosphere. Here, we firstly clarified the high abundance of SRB in deep-sea sediments via the operational taxonomic units (OTU) sequencing analysis. We have successfully isolated a sulfate-reducing bacterium (strain zrk46) from a cold seep sediment, by using an enriched medium supplemented with sulfate. Our genomic, physiological and phylogenetic analyses indicate that strain zrk46 is a novel species, which we propose be named: Pseudodesulfovibrio serpens. Based on the combined results from growth assays and proteomic analyses, we found that supplementation with sulfate (SO42-), thiosulfate (S2O32-), or sulfite (SO32-) promoted the growth of strain zrk46 by facilitating energy production through the dissimilatory sulfate reduction with the auxiliary functions of heterodisulfide reductases, ferredoxins, and nitrate reduction associated proteins, which were coupled to the oxidation of environmental organic matter in both laboratory and deep-sea in situ conditions. Moreover, metatranscriptomic results have also confirmed the dissimilatory sulfate reduction of deep-sea SRB in in situ environment, which might be coupled to the methane oxidation of anaerobic methanotrophic archaea (ANME-2). Overall, these findings expand our understanding of deep-sea SRB, while highlighting their importance for deep-sea sulfur and carbon cycles.

Project description:Seawater exposure to the gram negative marine bacterium Vibrio diazotrophicus induces a robust cellular response in sea urchin larvae that includes the migration of pigment cells to the gut epithelium, changes in cell behavior and altered gut morphology (Ho et al., 2016; PMID 27192936). To investigate the transcriptional underpinnings of this response, whole transcriptome sequencing was performed on mRNA isolated from larval samples collected at 0, 6, 12 and 24 hr of exposure to V. diazotrophicus. The morphological simplicity of the sea urchin larva provides a systems-level model for identifying biologically relevant transcriptional state changes in response to dysbiosis in the gut lumen.

Project description:Brown macroalgae holds an enormous potential as a future feedstock because it rapidly forms large biomasses and has high carbohydrate content (35% of its dry weight consists of alginate and mannitol). However, utilization of brown macroalgae by conventional microbial platforms (e.g., Escherichia coli and Saccharomyces cerevisiae) has been limited due to the inability of these platforms to metabolize alginate. Although recent studies engineered them to utilize alginate, their growth rates and metabolic activities are still too low for industrial applications, likely due to the unoptimized expression of multiple xenogeneic genes. Here, we isolated Vibrio sp. dhg, a novel, fast-growing bacterium that has been naturally evolved for efficient alginate assimilation (growth rate = 0.98 h-1). Especially, both the growth rate and sugar uptake rate of V. sp. dhg are substantially higher than the rates of E. coli for most biomass-derivable sugars. Based on our systematic characterization of its metabolism and gene expression architecture, we were able to develop a genetic toolbox for its engineering. By using this microorganism, we successfully demonstrated its ability to produce a broad spectrum of chemicals from alginate-mannitol mixtures with high productivities (1.1 g ethanol/L/h, 1.3 g 2,3-butanediol and acetoin/L/h, and 0.69 mg lycopene/L/h). Collectively, the V. sp. dhg strain is a powerful platform for the conversion of brown macroalgae sugars whose usage will dramatically accelerate the production of value-added biochemicals in the future.
