Optical microscopy and Raman spectroscopy were used on precipitates induced in solid media and only Raman analyses were done in liquid media. □: calcite type-CaCO3; Δ: undetermined type-CaCO3; Φ: no precipitates induced; β: no bacteria growth; d: dumbbell shape; cs: contiguous sphere shape; s: sphere shape; u: undetermined shape.
