Article Title: Characterisation of CaCO 3 phases during strain-specific ureolytic precipitation
doi: 10.1038/s41598-020-66831-y
Figure Lengend Snippet: Raman spectra of polymorphic CaCO 3 crystals formed in the presence of S. aquimarina (SA01-0.3M) evidencing the coexistence of calcite and vaterite within a single crystal and showing their spatial arrangement ( a ); and SEM BSE image of internal structure of biotic precipitates of S. aquimarina with some cores showing traces of vaterite spherulites (yellow dotted circle) and others that have started to be filled by advancing crystallisation steps (red solid circle) ( b ).
Article Snippet: This study focuses on three different ureolytic bacterial strains, all belonging to the Sporosarcina species: Sporosarcina pasteurii (ATCC 11859), Sporosarcina aquimarina (ATCC BAA-723), and Sporosarcina newyorkensis –a newly isolated microbe from the deep sea in offshore Japan extracted by the National Institute of Advanced Industrial Science and Technology (AIST) using pressure-core nondestructive analysis tools .
