Abstract microbeMASST, a taxonomically informed mass spectrometry (MS) search tool, tackles limited microbial metabolite annotation in untargeted metabolomics experiments. Leveraging curated database of >60,000 monocultures, users can known and unknown MS/MS spectra link them to their respective producers via fragmentation patterns. Identification microbe-derived metabolites relative without priori knowledge will vastly enhance the understanding microorganisms’ role ecology human health.
Seagrasses are among the most efficient sinks of carbon dioxide on Earth. While sequestration in terrestrial plants is linked to microorganisms living their soils, interactions seagrasses with rhizospheres poorly understood. Here, we show that seagrass, Posidonia oceanica excretes sugars, mainly sucrose, into its rhizosphere. These sugars accumulate µM concentrations-nearly 80 times higher than previously observed marine environments. This finding unexpected as readily consumed by...
Nitrite-oxidizing bacteria (NOB) have conventionally been regarded as a highly specialized functional group responsible for the production of nitrate in environment. However, recent culture-based studies suggest that they capacity to lead alternative lifestyles, but direct environmental evidence contribution marine nitrite oxidizers other processes has lacking date. We report on biogeochemical functions, worldwide distribution, and sometimes high abundance NOB

Lipids are an integral part of cellular membranes that allow cells to alter stiffness, permeability, and curvature. Among the diversity lipids, phosphonolipids uniquely contain a phosphonate bond between carbon phosphorous. Despite this distinctive biochemical characteristic, few studies have explored biological role phosphonolipids, although protective function has been inferred based on chemical stability. We analyzed two species marine mollusks, blue mussel Mytilus edulis pacific oyster...
Summary Seagrasses are one of the most efficient sinks carbon dioxide on Earth 1 : They bury 35 times faster than tropical rainforests a per unit area basis 2 . While we know that sequestration in terrestrial plants is intimately linked to microorganisms living their soils 3–6 , interactions seagrasses with rhizospheres poorly understood. We show three seagrass species from two oceans excrete simple sugars, mainly sucrose, into rhizosphere accumulate over 200 µM. Such high concentrations at...
