Bioremediation of Soils Contaminated with Gasoline in Bioreactors Containing Earthworms Eisenia Fetida and Mixture of Vermicompost and Raw Activated Sludge
Background and Aims: Nowadays, soil pollution with total petroleum hydrocarbons (TPH) is one of the major environmental issues caused serious problems to human and other living organisms. One of the best and most reliable methods of bioremediation is the use of earthworms known as vermin-remediation. In this study, bioremediation of gasoline-contaminated soil using Eisenia Fetida, the mixture o...
متن کاملPotential utilization of bagasse as feed material for earthworm Eisenia fetida and production of vermicompost
In the present work bagasse (B) i.e waste of the sugar industry, was fed to Eisenia fetida with cattle dung (CD) support as feed material at various ratios (waste: CD) of 0:100 (B0), 25:75 (B25), 50:50 (B50), 75:25 (B75) and 100:0 (B100) on dry weight basis. Co-composting with cattle dung helped to improve their acceptability for E. fetida and also improved physico-chemical characteristics. Bes...
متن کاملOxidative stress and DNA damage in the earthworm Eisenia fetida induced by toluene, ethylbenzene and xylene.
Superoxide dismutase (SOD), guaiacol peroxidase (POD), catalase (CAT), and the comet assay (SCGE) were used as biomarkers to evaluate the oxidative stress and genotoxicity of toluene, ethylbenzene and xylene in earthworms (Eisenia fetida). The results indicated that the exposure of the three pollutants caused a stress response of the three enzymes, an approximate bell-shaped change (a tendency ...
متن کاملThe effect of neutralized and non-neutralized pomegranate pulp on features of Eisenia fetida and vermicompost
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...
متن کاملEffect of silver nanoparticle surface coating on bioaccumulation and reproductive toxicity in earthworms (Eisenia fetida).
The purpose of this study was to investigate the effect of surface coating on the toxicity of silver nanoparticles (Ag NPs) soil. Earthworms (Eisenia fetida) were exposed to AgNO(3) and Ag NPs with similar size ranges coated with either polyvinylpyrrolidone (hydrophilic) or oleic acid (amphiphilic) during a standard sub-chronic reproduction toxicity test. No significant effects on growth or mor...
