Autor: Rui Zhang, Stéphane Blain, Corentin Baudet, Hélène Planquette, Frédéric Vivier, Philippe Catala, Olivier Crispi, Audrey Guéneuguès, Barbara Marie, Pavla Debeljak, Ingrid Obernosterer

Publikováno v: Limnology and Oceanography Letters, Vol 9, Iss 6, Pp 776-784 (2024)

Abstract Marine microbes are strongly interrelated to trace metals in the ocean. How the availability of trace metals selects for prokaryotic taxa and the potential feedback of microbial processes on the trace metal distribution in the ocean remain p

Marine Synechococcus cyanobacteria are ubiquitous in the ocean, a feature likely related to their extensive genetic diversity. Amongst the major lineages, clades I and IV preferentially thrive in temperate and cold, nutrient-rich waters, whilst clade

International audience; Trace elements (TE) are tracers of multiple biotic and abiotic processes in the ocean and some of them are essential for marine life. Vertical export by particles is a major removal process of a large fraction of TE from the s

Iron (Fe) limitation is known to affect heterotrophic bacteria within the respiratory electron transport chain, therefore strongly impacting the overall intracellular energy production. We investigated whether the gene expression pattern of the light

We investigated the metabolic response to iron (Fe) limitation of two bacterial strains of Alteromonas macleodii , isolated from a coastal and an oceanic marine environment. Bacteria were grown under Fe-limited and Fe-replete conditions, and comparat

International audience; In large regions of the open ocean, iron is a limiting resource for phytoplankton. The reduction of iron quota and the recycling of internal iron pools are among the diverse strategies that phytoplankton have evolved to allow
