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...
An ecotoxicity test with Eisenia fetida was performed to monitor the removal of diesel and toxicity variation during the ozonation process. The three-dimensional (3-D) cell test was introduced for the monitoring of the ozonation process, and the removal rate based on total petroleum hydrocarbons (TPHs) mass was about 95% near the ozone inlet ports. This high removal rate might be caused by the ...
The anecic earthworm Lumbricus terrestris L. was kept in laboratory microcosms containing beech forest soil without litter, with beech leaf litter or with lime leaf litter. The structure of microfungal communities in soil, litter and fresh and aged (100 days) earthworm faeces was analysed using the washing and plating technique. The passage of mineral soil through the gut of L. terrestris affec...
ورمی کمپوست (vermicompost)یکی ازغنی ترین کودهای آلی بوده که توسط گونه های خاصی ازکرم خاکی مانند savigny/1826)) eisenia foetida تولید می شود و کاربردهای فراوانی در پرورش گیاهان زینتی دارد. از جمله کاربرد های آن می توان به افزایش گلدهی گیاهان زینتی، کاهش زمان جوانه زنی دانه، افزایش محصول از لحاظ کمی و کیفی و غیره اشاره نمود. کرم خاکی به علت داشتن مقدار فراوان پروتئین و ویتامین در ساختار خود می ت...
In soils, organic matter decomposition and stabilization largely occur as a result of microbial activity, although when present, earthworms are important drivers of the processes through their interactions with microflora which begin during organic matter digestion by earthworms. Here, we studied the effects of gut transit on the number of bacteria and the microbial activity in pig slurry, usin...
