Impact of the earthworm Lumbricus terrestris ( L . ) on As , Cu , Pb and Zn mobility 1 and speciation in contaminated
17 To assess the risks that contaminated soils pose to the environment properly a greater 18 understanding of how soil biota influence the mobility of metal(loid)s in soils is 19 required. Lumbricus terrestris L. were incubated in three soils contaminated with As, 20 Cu, Pb and Zn. The concentration and speciation of metal(loid)s in pore waters and the 21 mobility and partitioning in casts were...

15 صفحه اولImpacts of epigeic, anecic and endogeic earthworms on metal and metalloid mobility and availability.
The introduction of earthworms into soils contaminated with metals and metalloids has been suggested to aid restoration practices. Eisenia veneta (epigeic), Lumbricus terrestris (anecic) and Allolobophora chlorotica (endogeic) earthworms were cultivated in columns containing 900 g soil with 1130, 345, 113 and 131 mg kg(-1) of As, Cu, Pb and Zn, respectively, for up to 112 days, in parallel with...
متن کاملCeramide glycanase from the earthworm, Lumbricus terrestris.
Ceramide glycanase (CGase) is an enzyme that cleaves the linkage between the sugar chain and the ceramide. To make this enzyme readily available, we have developed a simple method for preparing it from the earthworm, Lumbricus terrestris. The method involves Bio-Gel A-0.5m, octyl-Sepharose and p-aminophenylthiogalactoside-agarose column chromatography. By gel filtration, the molecular mass of e...
متن کاملOntogenetic scaling of burrowing forces in the earthworm Lumbricus terrestris.
In hydrostatic skeletons, it is the internal fluid under pressure surrounded by a body wall in tension (rather than a rigid lever) that enables the stiffening of the organism, the antagonism of muscles and the transmission of force from the muscles to the environment. This study examined the ontogenetic effects of body size on force production by an organism supported with a hydrostatic skeleto...
