酵母はCe酸化物ナノ粒子の存在により特異な有機物を排出した。Ceナノ粒子は酵母の生育への直接的な影響はないものの、グリコシシス酵素を排出した。このことから、Ceナノ粒子は酵母の代謝を変化させることが分かった。

Distinct organic species and intracellular proteins were expressed after exposure of yeast cells to CeNPs. Although cytotoxicity was not caused by CeNPs, the results of the peptide mass fingerprint analysis of the intracellular protein revealed that Eno2p, a glycolysis enzyme, was expressed after the exposure to CeNPs. These results suggest that nanoparticles have the potential to alter microbial metabolism, leading to changes in the compositions of the released substances in the surrounding environment.
