摘要：

Yarrowia lipolytica is known to synthesize cell-associated gold nanoparticles. Melanin, a pigment associated with the yeast, was identified as a factor responsible for nanoparticle synthesis. Cell-extracted melanin as well as that induced by incubating cells with 3,4-dihydroxy- L-phenylalanine (L-DOPA) mediated the synthesis of gold nanoparticles (AuNPs). These nanoparticles were characterized by a variety of standard techniques. This report identifies one of the molecular mechanisms involved in nanoparticle synthesis by Y. lipolytica. The nanoparticles thus synthesized were effective antibiofilm agents. (C) 2013 Elsevier B.V. All rights reserved.
