The correlations of glomalin contents and removal of phenanthrene and pyrene as representative polycyclic aromatic hydrocarbons (PAHs) in soils with inoculation of arbuscular mycorrhizal fungi(AMF) were investigated. The test AMF included Glomus etunicatum(Ge), Glomus mosseae(Gm), and Glomus lamellosum(Gla), and the host plant was alfalfa(Medicago sativa L.). The AMF hyphal density and contents of easily extractable glomalin and total glomalin in AMF-inoculated soils were observed to increase with cultivation time from 35 d to 75 d. Comparing with the control treatment(CK) without AMF inoculation, the contents of easily extractable glomalin in soil increased 48.58%, 55.99% and 50.23%, and total glomalin contents increased 38.75%, 50.95% and 46.12% with Ge, Gm and Gla inoculation after 75 d, respectively. AMF inoculation promoted the removal of test PAHs in soils. The removal rates of phenanthrene and pyrene in soils with AMF enhanced in 35~75 d. 83.4%~92.7%, 82.1%~93.8% and 86.9%~93.4% of phenanthrene and 42.2%~63.5%, 43.7%~69.2% and 44.6%~66.4% of pyrene in soils with Ge, Gm, Gla were removed in 75 d respectively. AMF hyphal density and total glomalin contents were observed to be significantly positively correlated with the removal rates of PAHs in soils, indicating that the colonization of AMF enhanced hyphal density and total glomalin contents and thus promoted the degradation of PAHs in the soil environments.
