Effects of ciprofloxacin exposure on the earthworm Eisenia fetida

Environmental Pollution, 2020
The widespread use of the antibiotic ciprofloxacin (CIP) poses a serious risk to soil organisms. Here, earthworms (Eisenia fetida) were used to explore the effect of CIP exposure on growth, reproduction, mortality, antioxidant enzyme activity, DNA damage, and mRNA levels.

Glyphosate but not Roundup® harms earthworms (Eisenia fetida)

Chemosphere, 2020
Glyphosate is the active ingredient in Roundup® formulations. While multiple studies have documented the toxicity, environmental persistence, and tendency to spread for glyphosate and Roundup®, few studies have compared the toxicity of glyphosate-based formulations to the toxicity of pure glyphosate for soil invertebrates, which contact both the ...

Effect of Pesticides on the Reproductive Output of Eisenia fetida

Bulletin of Environmental Contamination and Toxicology, 2007
We investigated the effects of three different pesticides (carbendazim, dimethoate, and glyphosate) and their mixture on the growth and reproduction of the earthworm species, Eisenia fetida. The study was conducted following the suggestion of the International Workshop on Earthworm Ecotoxicology.

Expression and characterization of ARSP1 from Eisenia fetida

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2004
To study the characterization of a protease ARSP1 (apoptosis-related serine protease) of Eisenia fetida, a recombinant ARSP1 was constructed. ARSP1 was produced in E. coli BL21-CodonPlus (DE3)-RIL after IPTG induction and exited in inclusion body. After refolding in vitro, the protein was purified by DEAE-Sepharose F.F.

Toxicity of metals to the earthworm Eisenia fetida

Biology and Fertility of Soils, 1985
Development of methods to measure the effect of man's residuals on soil ecosystems is desirable. Earthworms, as one of the largest and most easily obtained components of the soil biota, are suitable for evaluating perturbations to soil ecosystems.

Toxicity and bioaccumulation of bromadiolone to earthworm Eisenia fetida

Chemosphere, 2015
Bromadiolone, a potent second-generation anticoagulant rodenticide, has been extensively used worldwide for the field control of rodents. Invertebrates may be at risk from primary poisoning as a result of bromadiolone bait applications. However, there are few data regarding the toxicity and bioaccumulation of bromadiolone to earthworms.

The erythrocruorin of Eisenia fetida

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1982
The erythrocruorin of Eisenia fetida can be dissociated partially into its principal subunits, the putative one-twelfths of the molecule and smaller subunits, by three different methods: freezing and thawing (Af), exposure to alkaline pH (Aa) and aging (Ao). The isolated subunits possess a relative molecular mass of 310,000 +/- 20,000 by gel filtration

Oxidative stress of imidaclothiz on earthworm Eisenia fetida

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2017
Imidaclothiz, a kind of neonicotinoid insecticides, is developed as a commercial pesticide in China and used for the control of sucking and biting insects, including aphids, whiteflies, beetles and some Lepidoptera species as well. In recent years, more and more attention has been focused on the adverse effects of neonicotinoid insecticides on non ...

Cloning and Identification of MicroRNAs in Earthworm (Eisenia fetida)

Biochemical Genetics, 2011
MicroRNAs (miRNAs) (noncoding RNAs of 20-25 nucleotides) play important roles in the post-transcriptional regulation of gene expression in various eukaryotes and prokaryotes. Piwi-interacting RNAs function by combining with PIWI proteins to regulate protein synthesis and to stabilize mRNA, the chromatin framework, and genome structure.

Recycling of organic wastes by employing Eisenia fetida

Bioresource Technology, 2011
This paper reports the recycling of nutrients by vermicomposting of cow dung (CD), poultry droppings (PD) and food industry sludge (FIS) employing earthworms (Eisenia fetida). A total of six vermicomposting units were established and dynamics of chemical and biological parameters has been studied for 13 weeks. The waste mixture containing 50% CD+25% PD+
