Using natural processes as inspiration, the present
study demonstrates a positive correlation between zinc
metal tolerance ability of a soil fungus and its potential
for the synthesis of zinc oxide (ZnO) nanoparticles. A total
of 19 fungal cultures were isolated from the rhizospheric
soils of plants naturally growing at a zinc mine area in India
and identified on the genus, respectively the species level.
Aspergillus aeneus isolate NJP12 has been shown to have a
high zinc metal tolerance ability and a potential for extracellular
synthesis of ZnO nanoparticles under ambient conditions.
UV–visible spectroscopy, Fourier transform infrared
spectroscopy, X-ray diffraction analysis, transmission
electron microscopy, and energy dispersive spectroscopy
studies further confirmed the crystallinity, morphology,
and composition of synthesized ZnO nanoparticles. The
results revealed the synthesis of spherical nanoparticles
coated with protein molecules which served as stabilizing
agents. Investigations on the role of fungal extracellular
proteins in the synthesis of nanoparticles indicated that
the process is nonenzymatic but involves amino acids
present in the protein chains.
