  Background: Today, Vermi compost production process as one of the very good procedures in terms of economic,health, and environmental sustainability to stabilize the organic waste is discussed. The aim of this study was Vermi compost production from fruit and vegetable organization waste by earthworm (Eisenia Fetida). Methods: In order to evaluate the quantity of produced Eisenia Foetida and Vermi compost an investigation was conducted in Azadi fruit and vegetable organization. The experiment was completely randomized design with three replications. Treatments were fruit, leaf vegetable and lettuce, non leafly vegatables, paper and combination of four treatments, in similar conditions. Results: the amount of Vermi compost significantly increased by fruit, combination and non leafly vegetables. Also the numbers of mature Eisenia Foetida, significantly increased by fruit and combination. But there were no significant differences in number of immature worms. Total weight of mature and immature worms was increased significantly by using fruit, combination and non-leafy vegetables. The highest increase in the average body length of mature worms and the most used waste were observed during the use of fruit treatment. The results showed that Vermi-compost quality treatments examined were in the standard range and only in terms of the organic matter was higher than the standard level. Conclusion: The results of this study showed that using waste of fruit and vegetable for producing compost from Eisenia Foetida is fully justified. Manuscript profile

  Background: The high percentage of putrescible materials in generated waste in Iran, in one hand, and lack of proper lands for sanitary landfilling of waste (specially in the northern parts of the country), in the other hand, along with problems of collection, transportation and disposal of waste all make it necessary to think about vermicompost method as an efficient technique for disposal of organic waste. Method: The present study aims to investigate the degradation of domestic waste using specific earthworm ‘Eisenia foetida’. For this purpose, a wooden pilot including three floors was designed. Length, width and height of the pilot were 45, 25 and 65 cm respectively. Then 500 earthworms were collected manually and put on created media in the pilot. The domestic waste was added every week to the pilot, and after 60 days the compost was taken out. Finally, the important parameters in the produced compost were analyzed in the laboratory. Results: The result shows that providing proper situations like temperature range of 20-30 °C and moisture range of 60-75% and also appropriate aeration can lead to creation of a suitable place for the growth of earthworms and consequently conversion of organic wastes to rich compost. The ratio of C/N in the produced vermicompost was 14.53 (range of C/N is 10-20). Conclusion: One of the other advantages of this method is that it can also be used for increasing the earthworms as a food resource for domesticated animals and aquatic creatures.  Manuscript profile

  Organic wastes are includes domestic wastes, crop wastes, garden waste, agricultural and food processing industries, poultry and livestock waste, human waste, fruit and vegetable wastes, orchards and farms. One effective and affordable method in organic waste management using is earthworms to produce vermicompost fertilizer, in addition to reducing environmental risks; the nature of their turnover in fertilizer consumption has accelerated. Vermicomposting is through decomposition of organic wastes help certain species of earthworms. In general, there are about 3000 species of earthworms in different sizes from 0/6 to 330 cm. Only two species Eisenia foetida and Lumbricus rubellus due to production efficiency and ease of replication are most widely used in the production of vermicompost. Considering limitation of the right places disposal of organic wastes and from hand landfill and incineration adverse effects on public health and the environment, Vermicomposting using biotechnology earthworms a suitable option for is organic waste management.

  Earthworms are important factors in soil formation and nutrient cycles. These organisms rummage soil and reform its particles and structure that are too important in succession. Earthworm frequency is related to the component of plant residues because they were nourishrd by organic matter, litter and plant residues. So kind, substance and chemical component of plant residues effect on their population and activities. Because organic matter in forests is abundant, earthworms can be introduced as the most important factor that influences on soil fertilities and improvement of it. So we studied reciprocal relationship and correlation of earthworms and forests to show how they enrich and improve soil fertilities. Manuscript profile

  Background & aim: Wound healing is a complex programmed sequence of cellular and molecular processes. The objective of the present study was to evaluate the ability of earthworm’s hydro-alcoholic body extract (EBE) to heal the experimental skin wound in goldfish (Carassius auratus gibelio).Materials and Methods: Fish (independent triplicate, 14/group), for 14 days, were divided into 5 groups 1) negative control (Unwounded); 2) pseudo-control (sham): wound treated with EBE carrier (mixture of castor oil and white vaseline); 3) Positive control: wound treated with sodium phenytoin 1%; 4) 1 mg/gr EBE-treated wound, 5) 10 mg/gr EBE-treated wound. In this study, macroscopic and microscopic evaluations and collagen turnover (Hydroxyproline content) in the skin, along with determination of lysozyme activity in blood sera were carried out. Results: In fish in group 4 (1 mg/gr EBE-treated wound), an increase in the epithelium diameter, good presence and appropriate synthesis of collagen with and low edema in dermis; increased hydroxyproline content; and elevated blood lysozyme activity were observed comparing to other groups.Conclusion: Our results revealed that application of 1 mg/gr EBE might be as an effective medicinal material in the process of animal wound healing particularly in aquatics.
