Bacterial communities implantation in γ-sterilised soils over a 32-days period.
Undiluted (○), 102- (Δ) and 104-diluted (◊) populations and control sterilized soil (□).
Figure 2.
Abundance of 16S and 18S rDNA gene fragments in the constructed microcosms.
The number of rDNA gene fragments were determined by real time quantitative PCR from a standard curve relating the quantity of rDNA fragments as a function of the Ct value. The errors bars represent standard deviation from three replicate samples value.
Figure 3.
β-diversity analysis of the microcosms composition.
Phylogenetic dataset analyzed using jackknifed PCoA of the weighted pairwise UniFrac distances. The undiluted, 102- and 104-diluted microbiotas are respectively represented by orange, red and blue plain circles.
Figure 4.
Jackknifed Unweighted Pair Group Method with Arithmetic mean (UPGMA) cluster tree of the constructed microcosms.
UPGMA clustering was made from the 10 jackknifed weighted UniFrac distance matrix generated for each constructed microcosm.

L. monocytogenes L9 survival over a 30-days period.
In a natural soil (■), in the constructed soil microcosms with established undiluted (○), 102- (Δ) and 104-diluted (◊) microbiotas and in a γ-sterilised soil (□). The errors bars represent standard deviation from three replicate samples value.
