Toxicity of nanodiamonds to white rot fungi Phanerochaete chrysosporium through oxidative stress.

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.

Carboxylated graphene oxide-chitosan spheres immobilize Cu in soil and reduce its bioaccumulation in wheat plants.

Due to the strong interaction with pollutants and the huge adsorption capacity, graphene adsorbents are widely applied in water decontamination. However, graphene adsorbents are seldom used in soil remediation, because the adsorptive sites on graphene would be occupied by soil components. In this study, we prepared carboxylated graphene oxide-chitosan (GO-COOH/CS) spheres for the immobilization of Cu from water and soil.

Adsorptive decontamination of Cu2+-contaminated water and soil by carboxylated graphene oxide/chitosan/cellulose composite beads.

Graphene adsorbents have been applied to remove diverse pollutants from aqueous systems. However, the mechanical strength of most graphene adsorbents is low and the fragile graphene sheets are released into the environment. In this study, we prepared carboxylated graphene oxide/chitosan/cellulose (GCCSC) composite beads with good mechanical strength for the immobilization of Cu from both water and soil.

Biotransformation of Pristine and Oxidized Carbon Nanotubes by the White Rot Fungus .

Carbon nanomaterials are widely studied and applied nowadays, with annual production increasing. After entering the environment, the complete degradation of these carbon nanomaterials by microorganisms is proposed as an effective approach for detoxification and remediation. In this study, we evaluated the degradation of pristine multiwalled carbon nanotubes (p-MWCNTs) and oxidized multiwalled carbon nanotubes (o-MWCNTs) by the white rot fungus , which is a powerful decomposer in the carbon cycle and environmental remediation.

Carboxylation as an effective approach to improve the adsorption performance of graphene materials for Cu removal.

Graphene materials are high-performance adsorbents for water and soil remediation, whose oxygen containing groups bind to metal ions intensely. In this study, we prepared carboxylated graphene oxide (GO-OCHCOOH) sponge and investigated the adsorption behaviors of Cu on it by both experimental and computational approaches. Carboxylation largely improved the adsorption capacity from 23.

Fungal transformation of graphene by white rot fungus Phanerochaete chrysosporium.

The wide applications of graphene materials require the thorough investigation on their biosafety and environmental risks. Transformation of graphene materials is a fundamental issue in their environmental risk evaluations. The enzymatic degradation of graphene is widely reported using peroxidases, but the information on the fungal transformation of graphene is still unavailable.

Toxicity of carbon nanotubes to white rot fungus Phanerochaete chrysosporium.

Carbon nanotubes (CNTs) are widely used in diverse areas with increasing annual production, thus the environmental impact of CNTs needs thorough investigation. In this study, we evaluated the effect of pristine multi-walled CNTs (p-MWCNTs) and oxidized multi-walled CNTs (o-MWCNTs) on white rot fungus Phanerochaete chrysosporium, which is the decomposer in carbon cycle and also has many applications in environmental remediation. Both p-MWCNTs and o-MWCNTs had no influence on the dry weight increase of P.

Toxicity of Pristine and Chemically Functionalized Fullerenes to White Rot Fungus Phanerochaete chrysosporium.

Fullerenes are widely produced and applied carbon nanomaterials that require a thorough investigation into their environmental hazards and risks. In this study, we compared the toxicity of pristine fullerene (C) and carboxylated fullerene (C-COOH) to white rot fungus . The influence of fullerene on the weight increase, fibrous structure, ultrastructure, enzyme activity, and decomposition capability of was investigated to reflect the potential toxicity of fullerene.
