in this study, the earthworms of tehran province were investigated. specimens were collected from wet soil in 48 stations during 2011 and 2012. during the course of the study, eight earthworm species were identified, including: aporrectodea caliginosa (savigny, 1826), ap. rosea (savigny, 1826), dendrobaena veneta (rosa, 1886), dendrodrilus rubidus (savigny, 1826), eisenia fetida (savigny, 1826)...
سابقه و اهداف: امروزه فرایند تولید ورمی کمپوست بعنوان یکی از روشهای بسیار مناسب از لحاظ اقتصادی، بهداشتی و سازگاری با محیط زیست برای تثبیت مواد زاید آلی مطرح است. هدف از این مطالعه، تولید ورمی کمپوست از زباله شهری توسط کرم خاکی( (eisenia fetida در مقیاس خانگی می باشد. روش بررسی: در این مطالعه که بصورت تجربی انجام شد، در ابتدا مخزن پلاستیکی تولید ورمی کمپوست تهیه شد و سپس با استفاده از بستر او...
in the process of vermicomposting, the earthworms eisenia fetida have been exposed to various metals with different concentrations to study the effects on worms’ bioaccumulation. the study was carried within 14 days of exposure. five different chemical compounds in various concentrations were added as mixture solutions to the experimental containers. metals concentrations were measured in earth...
تحقیق حاضر در راستای کاهش مشکلات زیست محیطی ناشی از مدیریت نامطلوب زباله های شهری و با هدف امکان سنجی بازیافت زباله های تولید شده در سطح شهر مشهد از طریق به کارگیری آنها به عنوان بستر برای تولید ورمی کمپوست با استفاده از یک گونه کرم خاکی اپی ژیک به نام eisenia fetida انجام پذیرفت. این تحقیق در قالب یک طرح کاملا تصادفی با یک نوع بستر (شامل مخلوط زباله شهری و کود گاوی) و در 5 سطح اختلاط مواد بستر...
This paper reports the vermicomposting of food industry sludges (FIS) mixed with different organic wastes employing Eisenia fetida. A total of 10 vermicomposting units containing different wastes combinations were established. After 15 weeks significant increase in total nitrogen (N(total)) (60-214%), total available phosphorous (P(avail)) (35.8-69.6%), total sodium (Na(total)) (39-95%), and to...
Bioconversion of industrial wastes into nutrient rich product using earthworms is of double interest: on the one hand, a waste is converted into organic fertilizer for soil application and on the other, it controls accumulation of harmful waste that is a consequence of growing industrialization. This study reports the feasibility of utilization of vermicomposting technology for nutrient recover...
Earthworm fibrinolytic enzyme component A, a protein which functions both as a direct fibrinolytic enzyme and a plasminogen activator, was purified from the earthworm Eisenia fetida. Diffraction-quality single crystals of the protein were grown by the hanging-drop vapour-diffusion technique with ammonium sulfate as a precipitant. The crystals belong to the orthorhombic space group P2(1)2(1)2(1)...
Some protein pharmaceuticals from Chinese medicine have been developed to treat cardiovascular diseases, genetic diseases, and cancer. Bioactive proteins with various pharmacological properties have been successfully isolated from animals such as Hirudo medicinalis (medicinal leech), Eisenia fetida (earthworm), and Mesobuthus martensii (Chinese scorpion), and from herbal medicines derived from ...
