“…Such variation of effects with time of exposure (viz., cell division rate) was also observed for Pb, U, and Zn. The use of long-term exposure to contaminants has been suggested as a way to better assess toxicity when using bacteria (Dillon, 1993;Thomulka et al, 1993;Newman and McCloskey, 1996;Thomulka et al, 1996;Backhaus et al, 1997;Froehner et al, 2000). Such a long-term exposure Microtox -based bioassay has been developed, the Microtox Chronic Toxicity test (Bulich and Bailey, 1995;Bulich and Huynh, 1995;Johnson, 1998; see also http://www.…”

ABSTRACT:Metal toxicity is a function of the biology of the target organism and the chemical speciation of the metal. The toxicity of 11 metals was assessed with three cell-based bioassays based on marine organisms: the bacterium Photobacterium phosphoreum of the Microtoxா bioassay, an environmental strain of P. phosphoreum, and photocytes isolated from the brittlestar Ophiopsila californica. Metal speciation was calculated for three commonly used media: NaCl-based Microtoxா bioassay medium, artificial seawater glycerol, and artificial seawater. Decreased bioluminescence was considered a proxy for cell toxicity. In all three assays the elements Cd and Hg exhibited similar speciation as well as similar toxicity profiles. The element Cu was toxic in all three assays despite different metal speciation for the P. phosphoreum bioassay. The element Ag was toxic to both bacterial strains but not to photocytes despite a similar chemical speciation for all three assays. In general, the Microtoxா bioassay was sensitive to all metals (except Pb), whereas the photocytes were the least sensitive to the metals. The heightened response of the Microtoxா bioassay probably resulted from a combination of the limited complexing power of the medium and the greater sensitivity of the bacterial strain.

“…This assay uses a marine Gram negative bacterium, V. fischeri (NRRL B-11177) (Parvez et al, 2006;Lappalainen et al, 2001). This strain has been widely used in several commercial test kits i.e., Microtox, Aboatox, LUMIStox and ToxAlert (Backhaus et al, 1997). Wang et al (2002) and Rigol et al (2004) evaluated the toxicity of textile mill, and pulp and paper mill effluents, respectively, using LUMIStox 300, Microtox and ToxAlert kits.…”

“…The resultant curve generally resembles a sigmoid function that can be represented by the modified Weibull equation (Equation (12)) as already applied successfully in this form, e.g., by Backhaus et al [38] and Gendig et al [14]. The parameters m 1 (location parameter), m 2 (slope parameter), m 3 (saturation value, usually 100%) and m 4 (baseline parameter) were determined using the least squares method.…”

Discharge of toxic industrial wastewaters into biological wastewater treatment plants may result in inhibition of activated sludge bacteria (ASB). In order to find an appropriate method of detoxification, the wastewater of a pesticide-processing plant in Vietnam was treated with three different methods (Fe III , powdered activated carbon (PAC), Fenton (Fe II /H 2 O 2 )) analyzing the detoxification effect with the nitrification inhibition test (NIT), respiration inhibition test (RIT) and luminescent bacteria test (LBT). The heterotrophic ASB were much more resistant to the wastewater than the autotrophic nitrificants. The NIT turned out to be more suitable than the RIT since the NIT was less time-consuming and more reliable. In addition, the marine Aliivibrio fischeri were more sensitive than the nitrificants indicating that a lack of inhibition in the very practical and time-efficient LBT correlates with a lack of nitrification inhibition. With 95%, the Fenton method showed the highest efficiency regarding the chemical oxygen demand (COD) removal. Although similar COD removal (60-65%) was found for both the Fe III and the PAC method, the inhibitory effect of the wastewater was reduced much more strongly with PAC. Both the NIT and the LBT showed that the PAC and Fenton methods led to a similar reduction in the inhibitory effect.
