资源简介:
Use of nanoparticles (NPs) in several commercial products has led to emergence of novel contaminants of air, soil and water bodies. The NPs may exhibit greater ecotoxicity due to nano-scale dependent properties over their bulk counterparts. The present investigation explores the effect of <i>in vitro</i> supplementation of TiO<sub>2</sub>, silica and silver NPs on radial growth and ultrastructural changes in the hyphae and spores of two mushroom genera, <i>Ganoderma lucidum</i> and <i>Volvariella volvaceae.</i> A concentration dependent decrease in radial growth on NP amended potato dextrose agar medium was recorded. However, in comparison to control, there was decrease in radial diameter on supplementation with TiO<sub>2</sub> NPs while an increase was recorded for silica and silver NPs amendments as compared to their bulk salts at same concentrations after 48 h of incubation. Optical microscopy studies showed decrease in the number of spores while increase in spore diameter and thinning of hyphal diameter on NPs supplementation. Scanning electron microscopy analysis of fungal growth showed presence of deflated and oblong spores in two fruiting strains of <i>Ganoderma</i> while <i>Volvariella</i> exhibited decreased sporulation. Further, hyphal thinning and branching was recorded in response to NP amendments in both the test mushrooms. Enhancement of protein content was observed on NP compared to bulk supplementation for all cultures, concentrations and hours of incubation except for TiO<sub>2</sub> NPs. Likewise, bulk and NP supplementations (at 100 mg <i>L</i> <sup>−1</sup>) resulted in enhanced laccase activity with occurrence of laccase specific protein bands on SDS-PAGE analysis.
