Effect of acclimatization on earthworm's (Eisenia andrei) potential on olive mille wastewaters detoxification
Résumé
A laboratory vermicomposting (two months duration) was conducted to evaluate the effect of earthworm acclimatization (epigeic—Eisenia andrei) on decomposition and detoxification of olive mill wastewaters. The Earthworm growth rate and phenols reduction were superior in the mixture with acclimated earthworms (21.83 ± 0.01 mg worm−1 day−1 and 72% respectively), than mixture with unacclimated earthworms (4.67 ± 0.01 mg worm−1 day−1 and 41% respectively). The data reveal that acclimatization of earthworms is a promising alternative for OMWW detoxification and vermicomposting (using E. andrei) is a suitable technology for olive by-products conversion into value-added materials.
