Inhibition effects of various nano metal hybrid material against different fungal isolates on potato dextrose agar medium. Brass/CaCO3 (1,000 ppm) exhibited 100% antimicrobial effect against all the five tested fungi. Nano metal hybrid material Graphite-Nickel (G-Ni) showed 100% inhibition rate against Rhizopus stolonifer and showed 52.94–71.76% inhibition rates against other four fungal isolates. mFe0 showed inhibition rate of 54.12% and 66.71% against Penicillium pinophilum and R. stolonifer, respectively. nFe showed 40.06% inhibition rate against Aspergillus tubingensis. Other nano materials and carriers showed minimal inhibition effects against the tested fungal isolates. (A) P. pinophilum. (B) Talaromyces purpureogenus. (C) A. tubingensis. (D) Aspergillus fumigatus. (E) R. stolonifer. a, control; b, G-Ni; c, MgO-Fe-A; d, mFe0; e, nFe; f, Brass/CaCO3 (1,000 ppm).
