Cellular and Molecular Damage by Ganaxolide on Phanerochaete Chrysosporium

Abstract—Galaxolide (1, 3, 4, 6, 7, 8-hexahydro-4, 6, 6, 7, 8, 8-hexamethyl-cyclopenta-γ-2-benzopyran, HHCB) is recognized as a novel contaminant in water and has potential adverse impacts on aquatic organisms. The toxic effect of HHCB on Phanerochaete chrysosporium was investigated by exposure of the fungus in nitrogen-limited culture medium to various concentrations of HHCB. The cultivation results showed that both the size and the quantity of the mycelial pellets of P. chrysosporium could be reduced when the concentration of HHCB was higher than 300 mg/L. DNA damage of P. chrysosporium by HHCB was also detected. Comparing with that in the control, the percent polymorphism under different concentrations of HHCB increased, from 21.4% to 42.9%. In addition, the result of UPGMA (un-weighted pair group method of arithmetic means) dendrogram showed that the Simple Matching Coefficient (SM) was decreased with an increase in the concentrations of HHCB. Thus, as an environmental pollutant, HHCB has the toxic effect on P. chrysosporium at both cellular and molecular level.

Index Terms—AFLP, Phanerochaete chrysosporium, HHCB, DNA damaging effects.
