Abstract
A pot culture experiment was carried out to study the influences of arbuscular mycorrhizal (AM) fungi and bacteria on the bioremediation of DEHP polluted soil and the growth of mung bean. Bacillus sp.DW1 and Gordonia sp.DH3, two bacterial strains, as well as one AM fungal inoculum, Acaulospora laevis 90034 were alone or in combination applied to the soil with 100 mg·kg~ -1 DEHP. Non-inoculum was used as the control(CK). The plants were harvested after 60 days of growth. The results showed that AM fungi could colonize the roots of mung bean. Shoot dry mass of the bean was increased by AMF inocula, although there was no significant difference of the root between each treatment. The AM fungi also improved plant mineral nutrition by increasing phosphorus (P) content, but there was no influence on root colonization and plant growth by DW1 and DH3. The two bacterial strains and the AM fungi, alone or in combination, promoted the degradation of DEHP in soil obviously. The combination inoculation with DW1, DH3 and AM fungi,exhibited a well synergistic effect on DEHP degradation, and it could decrease the DEHP uptake by shoots of mung bean, which indicates that co-inoculation technique can play a role in phytoremediation of DEHP-contaminated soils.
