IRAZUSTA, Verónica; MICHEL, Lucas  and  DE FIGUEROA, Lucía I.C. Biomineralization of copper in Candida fukuyamaensis RCL-3. Rev. argent. microbiol. [online]. 2016, vol.48, n.2, pp.166-170. ISSN 0325-7541.  http://dx.doi.org/10.1016/j.ram.2016.03.007.

Candida fukuyamaensis RCL-3 yeast has the ability to decrease copper concentration in a culture medium. High copper concentrations change the cell color from white/cream to brown. The effect of color change ceases with the addition of KCN or when cells are grown in a culture medium without sulfate ions. These results could be associated with CuS bioaccumulation in the cell surface. This report revealed that mineralization would be a mechanism used by this yeast for copper bioremediation.
