In this study, different forms of magnetically responsive calcium carbonate (CaCO3) crystal composites were successfully formed from gaseous CO2 by using the different forms of polyethylene glycols (PEGs) in a constant CO2 pressure controlled chamber. Polygonal particles were produced with more rigid polymer chains (branched PEG), whereas less rigid polymer chains (PEG) induced the formation of ellipsoidal particles. However, no morphological changes occurred without the presence of CA. © 2013 Elsevier B.V.en1873-486320132208211BiomineralizationCalcium carbonateCarbon dioxideCarbonic anhydrasePolymerBiowissenschaften, BiologieJournal Article10.1016/j.jbiotec.2013.06.024Other
