When Oxygen Precedes Sugar: Another Story of Photosymbiosis

A team from BIAM, in collaboration with the Laboratoire de Chimie Bactérienne (LCB), proposes a new scenario for the origin of photosymbioses. Their work suggests that oxygen produced by photosynthesis, rather than sugars, may constitute the initial advantage of these associations that profoundly transformed the biosphere. Photosymbioses—the intimate associations between a non-photosynthetic organism and a […]

Nuclear decontamination: a bacterium that captures strontium-90

As part of a French collaboration1, BIAM researchers have just demonstrated the decontamination capabilities of a cyanobacterium: Gloeomargarita lithophora, which captures strontium-90 (90Sr), a radionuclide present in power plant effluents. This discovery opens the way to highly effective, environmentally-friendly bioremediation. Co-discovered several years ago by IMPMC1 in a stromatolite from Lake Alchichica in Mexico, a […]

When daughter cells take flight: thank you, kinase!

Microalgae and biomass BIAM scientists have identified the crucial role of a plant-specific kinase in regulating daughter cell hatching in microalgae. This breakthrough enables better management of cell wall degradation, facilitating the release of daughter cells and biomass production. One of the main challenges in using microalgae to produce fuel is to understand how to […]

Unlocking Plant Resilience: Evolutionary Synergy in Stress Adaptation

A groundbreaking mechanism enabling plants to optimize their photosynthesis has been unveiled by a scientific collaboration led by the BIAM. Remarkably, this discovery involves molecules of bacterial origin, and opens promising avenues for developing agriculture that is more resilient to climate change. Chlorophyll fluorescence images of plants for analysis of photosynthetic activity Photosynthesis, fundamental to […]
