Atrazine is one of the most used herbicides and its over-application in fields can affect soils their associated biota. In this work, earthworms (Eisenia fetida) were exposed to different concentrations atrazine assess possible sublethal harmful effects. search for reliable biomarkers these effects, acetylcholinesterase (AChE), alkaline phosphatase (ALP) lactate dehydrogenase (LDH) activities m...

A cryptic fungal endophyte, Neotyphodium coenophialum, infects most tall fescue (Festuca arundinacea) pastures in the United States. Cattle, sheep, and horses that consume the endophyte-infected grass can suffer fescue toxicosis caused by toxic alkaloids in the infected plants. The effects of the endophyte on mammalian herbivores have been well documented, but less is known regarding the qualit...

phytoremediation is a sustainable and environment friendly remediation technique, the potential of which in removal of soil contaminants has been well documented. on the other hand the activity of earthworms helps improve soil conditions. hence, it is expected that in soil presence of earthworms can enhance the rate of phytoremediation as regards anthracene. the aim followed in this work was to...

BACKGROUND Epigeic earthworms are key organisms in organic matter decomposition because of the interactions they establish with microorganisms. The earthworm species and the quality and/or substrate availability are expected to be major factors influencing the outcome of these interactions. Here we tested whether and to what extent the epigeic earthworms Eisenia andrei, Eisenia fetida and Perio...

Soil heavy metal pollution is widespread and has severe adverse effects on soil organisms. Earthworms are the major organisms which perform several beneficial ecological functions butare vulnerable to damage from of soil. The present study was conducted evaluate potential toxicity arsenic (As) chromium (Cr) biochemical response earthworm, Eisenia fetida. Following exposure various sub-lethal co...

Earthworms represent an important food source for many vertebrates and as a result, predators may encounter toxic effects via the food chain from consumption of contaminated worms. Therefore, including an assessment of xenobiotic to worms in risk assessment procedures is advisable. Here we studied the acute toxicity, bioaccumulation and elimination of ethofumesate enantiomers in earthworm, Eise...

Although groups of earthworm proteases have been found by several laboratories, it is still unclear how many of the isolated trypsin-like fibrinolytic enzymes are in glycosylated form. Here, eight glycosylated fibrinolytic proteases (EfP-0-1, EfP-0-2, EfP-I-1, EfP-I-2, EfP-II-1, EfP-II-2, EfP-III-1 and EfP-III-2) were isolated from an earthworm species (Eisenia fetida) through a stepwise-purifi...

ABSTRACT - Vermicomposting with pomegranate pulp can not only prevent pollution of the environment but can also create jobs, generate added value and prevent the waste of energy and the country's capital. This factorial experiment was conducted in a completely randomized design. The first factor (a) in two levels contained neutralized pomegranate pulp with lime and non-neutralized pulp. The sec...
