“…The activated sludge treatment decreased the risk associated to the textile effluent; actually, the BRS of E2 was lower than E1. This result is a consistent indicator of the detoxifying capacity of the tested activated sludge, which is in accordance with the literature, which indicated that activated sludge is effective in reducing textile effluent toxicity (Anastasi et al 2012;Giorgetti et al 2011;Araújo et al 2005). The ecotoxicity decrease was proportional to the decrease of chemical parameter (pH, COD and BOD), confirming the effectiveness of bioremediation power of the activated sludge.…”

Textile industry is considered as one of the important factors of the economic growth in Tunisia. However, this prominent role has certainly some drawbacks mainly represented by the huge amounts of textile wastewaters generated that become a real menace to nature. Many previous studies showed the purifying potential of some activated sludge and bacteria (Pseudomonas putida) to decolourize textile effluents. However, in many cases, decolourization of wastewaters is not necessary associated with detoxification, generating a real risk for the ecosystem in general. We evaluated in this work the induced toxicity of a textile effluent before and after its treatment with activated sludge followed by P. putida, using a battery of biotests. This study proved the detoxifying power of the activated sludge according to most of ecotoxicity tests. The treatment with P. putida did not improve the quality of the effluent; on the contrary, it could increase its toxicity. Daphnia magna and Raphidocelis subcapitata appear to be the most sensitive organisms in assessing eventual toxicity caused by this kind of wastewaters.

“…In this context, it should be mentioned that in order to evaluate the eventual efficacy of an applied remediation strategy, numerous bioassays have been already standardized in relation to the different environmental matrices and the assessment of the ecological impact of water contaminants on plants is considered a fundamental assay since plants come into direct contact with contaminated water through their root system (Abdel Migid et al 2007). As a matter of fact, the large use of plants in phytotoxicity and genotoxicity tests has already been reported by several authors (Giorgetti et al, 2011). The phytotoxicity of the effluents before and after the phyto-based approach here described has been evaluated by bioassays carried out on seeds of L. sativum and in V. faba.…”

In the present study, the quality of effluents from a conventional wastewater treatment plant in Italy has been analyzed. Residual level of contamination by 4-nnonylphenol, mono-and di-ethoxylated nonylphenols has been recorded in the effluents that resulted to be also phytotoxic and genotoxic. The possibility of exploiting phytoremediation as a sustainable tertiary treatment for the depletion of the priority pollutants and for the reduction in the residual toxicity has been verified at mesocosm scale. The phyto-based treatment has been performed by the exploitation of Phragmites australis by either a bacterialassisted and not assisted approach. In relation to the bacterial-assisted approach, two new bacterial strains, capable of using the nonylphenols as a sole carbon source, have been isolated. One was identified as a plant growth-promoting rhizobacteria (PGPR) belonging to the Stenotrophomonas species, and the second one was classified as a Sphingobium species strain. Both strains were independently bioaugmented in the P. australis rhizosphere. In relation to the not assisted approach, the phyto-based process determined 87, 70 and 87 % for 4-n-nonylphenol, mono-ethoxylated nonylphenols and di-ethoxylated nonylphenols, respectively. The toxicological assessment of the process evidenced the complete depletion of either the phytotoxicity or the genotoxicity of the treated effluents. With reference to the bacterial-assisted approach, the PGPR Stenotrophomonas species strain resulted to be capable of significantly increasing the efficiency of the phyto-based process in nonylphenol depletion up to 88 % for the 4-n-nonylphenol, 84 % for the mono-ethoxylated nonylphenol and 71 % for the di-ethoxylated nonylphenol.
