قابلیت کرم های خاکی برای بازیافت محدوده وسیعی از ضایعات آلی به خوبی شناخته شده است. معدودی از گونه های کرم های خاکی برای تولیـد تجـاری ورمی کمپوست ها مناسب اند و از این میـان دو گـونه foetida eisenia و lumbricus rubellus در مناطق معـتدله یافت می شوند. نمونه های کرم های خاکی از مناطق شمال و شمال غرب کشور و از داخل توده های قدیمی کود دامی و لاشبرگ های سطحی جمع آوری و در شرایط گلخانه ای نگه داری ش...
ورمی کمپوست که طی فرآیند تجزیه زیستی مواد زاید آلی توسط گونههای خاصی از کرمهای خاکی تولید می گردد؛ کود آلی بسیار مغذی، بیبو و با قابلیت زیاد اصلاح کنندگی خاک است. هدف از این تحقیق تولید ورمی کمپوست با استفاده از بستر کود گاوی و کرم خاکی foetidaeisenia و بررسی روند تغییرات پارامترهای فیزیکوشیمیایی و زیستی در فرآیند تولید ورمی کمپوست و دستیابی به تولید بهینه کود و کرم است. در طول دوره چهار ماه...
BACKGROUND The aim of this study was to determine the potential of produced compost from the sludge of wastewater treatment plant using earthworms and compare it with the vermicompost produced from household solid waste. METHODS In the current study, three treatments with the same conditions in terms of organic wastes type were prepared to produce vermicompost from household solid waste and s...
western model predicted the site of two other tropical kelp species off Cabo Frio in Brazil. The researchers also came across a reference to another deep-water kelp species off the Philippines. This species was last known to science following collection from a site predicted by the model to be suitable for tropical kelp. With these predictions to hand, the team decided earlier this year to moun...
Earthworms are the most suitable biological indicators of radioactive pollution because they are the parts of nutritional webs, and are present in relatively high numbers. Four months old Eisenia fetida were exposed to different doses of gamma radiation, namely 1, 2, 3, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 & 60 Gy to study the effects of radiation on different reproductive parameters. The ...
Introduction The earthworm coelomic fluid (ECF) has shown proven antiproliferative effect against breast, liver, gastrointestinal, and brain cancer, but it is least explored in oral cancer. The present in vitro study is an attempt to investigate the antiproliferative activity of ECF on oral cancer cell line squamous cell carcinoma (SCC)-9. Materials and Methods ECF was collected from the spec...
The responses of wheat Triticum aestivum, rice Oryza sativa, earthworms Eisenia foetida, and prawns Penaeus japonicus to combined acetochlor-Cu, Cd-Zn were studied in hydroponic and soil-culturing systems using the methods of ecotoxicology. In particular, systematically quantitative analyses were documented by field experiments. Results showed that ecotoxicological effects under the combined po...
Acute and chronic ecotoxicity tests with zinc were performed with the earthworm Eisenia fetida, the potworm Enchytraeus albidus, and the springtail Folsomia candida. To assess the influence of the soil type on zinc toxicity for these soil invertebrates, these tests were carried out in a standard artificial soil, a sandy and a loamy field soil. Based on the results of this experimental work and ...
This study compared the uptake and depuration of four commonly used pharmaceuticals (carbamazepine, diclofenac, fluoxetine and orlistat) in two earthworm species (Lumbricus terrestris and Eisenia fetida). L. terrestris are a larger species and often found in deep burrows whereas E. fetida prefer to reside near the soil surface. Species burrowing habits and sizes may alter uptake by earthworms. ...
