Photosynthetic metabolite used for nitrogen fixation

ABSTRACT: Using 13C bicarbonate labelling, metabolites from photosynthesis will be identified and depletion of metabolites after 1hour of photosynthesis inhibition will reveal metabolites used for nitrogen fixation. Bicarbonate will be added at the beginning of the day, and samples will be taken after 5hours. Cells will be treated with DCMU (photosynthesis inhibitor) at this 5h timepoint and left for an additional 1h incubation. Final samples will be taken at 6h (1 hour after DCMU addition) to assess depletion of the photosynthetic metabolites. The work (proposal:https://doi.org/10.46936/10.25585/60008462) conducted by the U.S. Department of Energy Joint Genome Institute (https://ror.org/04xm1d337), a DOE Office of Science User Facility, is supported by the Office of Science of the U.S. Department of Energy operated under Contract No. DE-AC02-05CH11231.

The influence of nutrients on microbial interactions and secondary metabolites in toxic cyanobacterial blooms

Project description:We describe metabolomics from microbial communities of western Lake Erie, a valuable model system for the impacts of nutrient cycling and microbial interactions on cyanobacterial blooms and secondary metabolites in freshwater ecosystems. We will assess the role of associated bacteria and viruses in cycling nutrients, exchanging metabolites, and influencing secondary metabolite production of these cyanobacteria.

Elucidate metabolism of bioenergy-relevant Clostridial and Streptomyces species

Project description:The goal of this study is to use both "targeted" and "untargeted" metabolomics to elucidate metabolism of Clostrial and Streptomyces species for biofuel production and plant growth promotion, respectively. For these species, we aim to improve the curation of genome-scale metabolic networks and elucidate their novel secondary metabolism to make secondary metabolites whose identities are waiting to be discovered. These metabolic networks will be used to study cell physiology, metabolism, regulation, and metabolic engineering.

Temperature Effects on Metabolite-Mediated Autotroph-Heterotroph Carbon Transfer

Project description:Much of the bacterial secondary production in the aquatic ecosystems is supported by rapid uptake of labile metabolites released from phytoplankton, either directly through excretion and diffusion or indirectly through lysis and predation. This project seeks to investigate the effects of temperature stress on the metabolite pools produced and released by three model phytoplankton species (a diatom, a coccolithophore, and a cyanobacterium) that will assess changes in the composition and fate of metabolites transferredto bacteria. While focused on estuarine microbes, findings of this project will be broadly relevant to temperature effects on microbial autotrophic-heterotrophic metabolite transfer in freshwater, marine, and soil ecosystems.
