Grand Prize of the jury of the 2022 CNRS photo competition La Proof par l’image, this photo shows a bacterial spore nestled in cells of wheat straw from cattle manure. When this manure is stored dried, some bacteria resist by going dormant in the spore state, waiting for more favorable conditions. After rehydrating the manure, the bacteria will resume their organic matter degradation activity, thus contributing to increasing the fertility of the soil on which it will be spread. baptized The eye of the cyclops keeps watchthis photo taken using a transmission electron microscope was presented to the competition by Françoise Watteau, from the Inrae-CNRS OTELo scientific center (Lorraine Earth and Environment Observatory) from the University of Lorraine, and Thierry Morvan, from the Center in economics and management from the University of Rennes.
