Abstract
Nanodiamonds (NDs) are produced with large scale and applied in many areas, thus the environmental impacts and hazards of NDs should be systematically investigated. In this study, we evaluated the interaction between detonation NDs and white rot fungus Phanerochaete chrysosporium and the impact on the fungus decompositions activities. NDs did not influence the biomass gain of P. chrysosporium and the culture medium pH values. The mycelia of P. chrysosporium were destroyed upon the direct contact with NDs, while the rest retained the fibrous structure. Ultrastructural observations suggested that small aggregates of NDs seldom entered the fungus cells, but the break of cell wall and the loss of cytoplasm were induced by NDs. Under both optical and electron microscopes, the aggregation of colloidal ND particles was observed, which was the possible reason of low toxicity. High concentrations of NDs inhibited the laccase activity and manganese peroxidase activity of P. chrysosporium, which led to the decrease of decomposition activity for pollutants. Colloidal ND particles were not well dispersed in sawdust degradation evaluations, so no inhibitive effect was observed for wood degradation. The toxicological mechanism of NDs was assigned to oxidative stress. The results collectively suggested that NDs had low toxicity to white rot fungi and could be applied safely. The colloid dispersion/aggregation of nanoparticles in biological systems should be carefully considered during the design of safe nanomaterials.
