Whilst many studies have investigated the influence of earthworms on soil microflora little work
has investigated the role of soil microflora on earthworm survival.
Here we tested the survival capacities of axenic and non-axenic earthworms exposed to sterile
and non-sterile soils. Axenic earthworms were produced by culture in a microcrystalline cellulose
and antibiotics solution. Then, they were inoculated in a sterilized soil re-inoculated or not with a
suspension of microorganisms extracted from the original non-sterile soil. Non-axenic earthworms
were cultured in the same microcrystalline solution without addition of antibiotics. Then, they
were added to non-sterile (control) soil, to sterile autoclaved soil or to the re-inoculated soil.
Earthworm survival was measured over 5 weeks. A DGGE analysis was performed on the soils
and the surviving depurated earthworms.
Within two days after their inoculation in the sterile soil, all the axenic earthworms died. In contrast,
all the axenic worms in the re-inoculated soil survived until the end of the experiment. The same
results were obtained with non-axenic earthworms. The DGGE showed a similar bacterial
community structure between the digestive tract of the axenic and non-axenic earthworms coming
from re-inoculated soils. However, the bacterial community structure was different in the nonaxenic
earthworms in the non-sterile soil (control).
The results of this experiment suggest (i) an absolute necessity of soil microflora for the survival
of earthworms, and (ii) that this dependence is not mainly linked to bacterial species but probably
to bacterial functional roles. MenosWhilst many studies have investigated the influence of earthworms on soil microflora little work
