Présence de bactéries biocalcifiantes et de matière organique dans le dépôt calcomagnésien (DC) [167]. (A) Présence de bactéries marquées au DAPI dans le DC formé à −100 µA/cm2 (flèche blanche) observée par microscopie à fluorescence ; (B) Image du DC obtenu à −100 µA/cm2 avec Pseudoalteromonas CD10 en microscopie µ-Raman ; (C) Spectres Raman du DC dans les zones (1) et (2) indiquées par les flèches marron-orangées en B et correspondant à la calcite magnésienne.
