摘要: In this paper, we report a biogenic synthesis protocol for preparation of calcium oxalate (CaC2O4, CaOx) crystal at room temperature by simple protein-mediated reaction aqueous Ca2+ ions with the C2O4(2-) spontaneously released from spinach. The aggregation monohydrate (COM) and dihydrate (COD) rod-like morphology was mainly formed in spinach root lixivium, proportion COM increased concentration increasing, however, spindle-shaped obtained leaf lixivium content product higher than that similar ions. phase disappeared only COD tetragonal bipyramidal prisms presented when replaced broth. biomolecules such as proteins molecular weight 31kDa liberated are negative-charged, which played important roles control CaOx growth corresponding to changes protein secondary structures after This research potentially unraveling biomineralization mechanism crystal.
