Microbial Biomineralization of Alkaline Earth Metal Carbonates on 3D-Printed Surfaces.

ABSTRACT: The biomineralizing bacterium Sporosarcina pasteurii has attracted considerable interest in the area of geotechnical engineering due to its ability to induce extracellular mineralization. The presented study investigated S. pasteurii's potential to induce the mineralization of alkali-earth metal carbonate coatings on different polymeric 3D-printed flat surfaces fabricated by different additive manufacturing methods. The use of calcium, barium, strontium, or magnesium ions as the source resulted in the formation of vaterite (CaCO₃), witherite (BaCO₃), strontianite (SrCO₃), and nesquehonite MgCO₃·3H₂O, respectively. These mineral coatings generally exhibit a compact, yet variable, thickness and are composed of agglomerated
