This work sets out to investigate biological responses of Eisenia fetida to Cd, based on the bioavailable rather than total concentration of Cd, in soils. E. fetida was cultured for 14d in three selected Chinese soils amended with 0.1-40mgkg-1 Cd. Potentially bioavailable concentrations of Cd were measured in soil solution, in extractions using CaCl2 and HAc solutions, and using the technique o...

Coelomic fluid of Eisenia foetida earthworms contains a 42-kDa protein named coelomic cytolytic factor 1 (CCF-1) that was described previously to be involved in cytolytic, opsonizing, and hemolytic properties of the coelomic fluid. Cloning and sequencing of CCF-1 reveal significant homology with the putative catalytic region of beta-1,3- and beta-1,3-1,4-glucanases. CCF-1 also displays homology...

POPOVIĆ, M., M. GRDIŠA, T. M. HRŽENJAK: Glycolipoprotein G-90 obtained from the earthworm Eisenia foetida exerts antibacterial activity. Vet. arhiv 75, 119128, 2005. ABSTRACT G-90 is a glycolipoprotein mixture obtained from the tissue homogenate of earthworm Eisenia foetida (Annelida, Lumbricidae) which exhibits pleiotropic biological functions. The antibacterial activity of G-90 was investigat...

This study was conducted to investigate the feasibility of vermicomposting by using vermicast as the substrate for the stabilization of municipal activated sludge, called hereafter as direct vermistabilization, in which the pre-treatment and bulking materials required in previous practices were all omitted. For this purpose, two epigeic earthworm species, namely Eisenia foetida and Bimastus par...

Se realizó compra en el distrito Chachapoyas se obtuvo con excavaciones, seguidamente fueron colocados individua...

This study aimed at assessing the influence of soil properties on the uptake and toxicity effects of arsenic in the earthworm Eisenia andrei exposed for 4 weeks to seven natural soils spiked with different arsenic concentrations. Water-soluble soil concentrations (AsW) and internal As concentrations in the earthworms (AsE) were greatly different between soils. These two variables were highly co...

Eisenia fetida were exposed continuously to (60)Co gamma radiation during two generations (F(0) and F(1)). Adult F(0) reproduction capacity (i.e., number of cocoons produced, hatchability and number of F(1) hatchlings) in controls and at five dose rates (0.18, 1.7, 4, 11 and 43 mGy/h) was measured over a 13-week exposure period. Survival, growth and sexual maturation of F(1) hatchlings were obs...

The effects of adding the biosurfactant rhamnolipid, the lignolytic and cellulolytic fungus Phanerochete chrysosporium, and the free-living nitrogen-fixing bacterium Azotobacter chrococcum on vermicomposting of green waste with Eisenia fetida was investigated. The addition of rhamnolipid and/or either microorganism alone or in all combinations significantly increased E. fetida growth rate, the ...
