Mt. Gonzalezmunoz et al., STRUVITE AND CALCITE CRYSTALLIZATION INDUCED BY CELLULAR MEMBRANES OFMYXOCOCCUS-XANTHUS, Journal of crystal growth, 163(4), 1996, pp. 434-439
In this work we have proved that struvite and calcite crystals can be
obtained in the presence of the cellular membrane fraction of Myxococc
us xanthus, when appropriate supersaturated solutions are used. Probab
ly, the negative charged points of the external side of the cellular s
tructures could reduce the metastability field of struvite and calcite
, acting as heterogeneous nuclei of crystallization.
