“…Our toxicity biosensor has a comparatively wide dynamic linear range. Although the LOD of E. coli GFP toxicity biosensor is not as low as others, it has an IC50 value which is higher as compared to the one reported by Taranova et al [23]. E. coli GFP toxicity biosensor is able to respond to SDS detection in seconds, while the reported biosensors would need minutes.…”

“…Not many SDS-detection biosensors have been reported. While several bacterial biosensors were produced to assist SDS detection, most of them were reported to have long response time (minutes to hours), short dynamic linear range, low reproducibility, and short term of stability [22][23][24]. In this study, we report a sensitive SDS-detection toxicity biosensor fabricated with immobilization of E. coli GFP which was found to have improved properties.…”

Green fluorescent protein (GFP) is suitable as a toxicity sensor due to its ability to work alone without cofactors or substrates. Its reaction with toxicants can be determined with fluorometric approaches. GFP mutant gene (C48S/S147C/Q204C/S65T/Q80R) is used because it has higher sensitivity compared to others GFP variants. A novel sodium dodecyl sulfate (SDS) toxicity detection biosensor was built by immobilizing GFP expressing Escherichia coli in k-Carrageenan matrix. Cytotoxicity effect took place in the toxicity biosensor which leads to the decrease in the fluorescence intensity. The fabricated E. coli GFP toxicity biosensor has a wide dynamic range of 4-100 ppm, with LOD of 1.7 ppm. Besides, it possesses short response time (<1 min), high reproducibility (0.76% RSD) and repeatability (0.72% RSD, 2 > 0.98), and long-term stability (46 days). E. coli GFP toxicity biosensor has been applied to detect toxicity induced by SDS in tap water, river water, and drinking water. High recovery levels of SDS indicated the applicability of E. coli GFP toxicity biosensor in real water samples toxicity evaluation.

“…The comparative data on application of bacteria from the genera Pseudomonas and Achromobacter in the amperometric biosensor for SAS detection are presented. The substrate specificity of several strains towards a wide range of compounds has been assessed (Taranova et al, 2002;Taranova et al, 2004). The microbial biosensor based on a column reactor containing activated sludge bacteria oxidizing linear alkylbenzene sulfonates was used for SAS analysis in river water.…”

“…The limit of detection achieved for sodium dodecyl sulfate (SDS) was within 0.25-0.75 mg/l [71]. Taranova et al [72] also studied the sensitivity and selectivity of biosensors based on bacterial strain Pseudomonas and Achromobacter and their ability to degrade the anionic surfactants. The degradation of surfactants by the bacteria caused a decrease in dissolved oxygen and a change in the oxygen electrode current.…”

Biosensors can be excellent analytical tools for monitoring programs working to implement legislation. In this article, biosensors for environmental analysis and monitoring are extensively reviewed. Examples of biosensors for the most important families of environmental pollutants, including some commercial devices, are presented. Finally, future trends in biosensor development are discussed. In this context, bioelectronics, nanotechnology, miniaturization, and especially biotechnology seem to be growing areas that will have a marked influence on the development of new biosensing strategies in the next future.
