  abstract = {{T}he hypothesis tested in this present study was that the ectomycorrhizosphere effect on the bacterial community was not root-growth-dependent. {T}he impacts of ectomycorrhizal infection ({P}isolithus albus {COI}007) and a chemical fertilization to reproduce the fungal effect on root growth were examined on (1) the structure of bacterial community and (2) fluorescent pseudomonad and actinomycete populations in the mycorrhizosphere of {A}cacia auriculiformis using both culture-independent and culture-dependent methods. {A}. auriculiformis plants were grown in disinfested soil in pots with or without addition of the ectomycorrhizal fungus or {N}/{P}/{K} fertilization (to reproduce the fungal effect on root growth) for 4 months and then transferred to 20-{L} pots filled with nondisinfested sandy soil. {T}he fungal and fertilizer applications significantly improved the plant growth after 4-month culture in the disinfested soil. {I}n the nondisinfested cultural substrate, these positive effects on plant growth were maintained. {T}he total soil microbiota was significantly different within the treatments as revealed from {DNA} analysis [denaturing gradient gel electrophoresis ({DGGE})]. {T}he structure of fluorescent pseudomonad populations was also affected by fungal and fertilizer applications. {I}n contrast, no qualitative effect was observed for the actinomycete communities within each treatment, but fungal inoculation significantly decreased the number of actinomycetes compared to the fertilizer application treatment. {T}hese results show that the mycorrhizosphere effect is not root-growth-dependent but is mainly due to the presence of the ectomycorrhizal fungus and more particularly to the extramatrical mycelium.},
