Biodesign
is an interdisciplinary field in which biological processes are combined with
many different fields to produce environmentally friendly and economically
feasible products. Within the scope of this study, first CaCO₃
production potential of Sporosarcina pasteurii
has been observed and optimized, and then the capability of hardening of
the sand is examined. The optimum CaCl₂ concentration for maximized
CaCO₃ formation was found as 50 mM. The ecological urban element was
designed and its mold was produced by 3D printer at lab scale. The Sporosarcina pasteurii was mixed with
sand and filled into the mold. The sand was mixed with 50 mM CaCl₂
solution every day until hardening is observed. At the end of one week, a
sitting element from hardened sand was produced. The CaCO₃ formation
was observed with XPS analysis. Thus, an interdisciplinary approach was used to
produce ecological biodesign products.v
