“…Several methods are commonly used to estimate the (bio)available fraction of the contamination. Mild extractions [7,8], cyclodextrine extraction [9,10], Tenax resin extraction [4],passive samplers [11,12], biosensors [13] and microbial incubations [14,15] can be cited. Another method was investigated by Cuypers et al [16] implying the application of chemical oxidant.…”

Three chemical oxidation treatments (KMnO4, H2O2 and Fenton-like) were applied on three PAH-contaminated soils presenting different properties to determine the potential use of these treatments to evaluate the available PAH fraction. In order to increase the available fraction, a pre-heating (100 °C under N2 for one week) was also applied on the samples prior oxidant addition. PAH and extractable organic matter contents were determined before and after treatment applications. KMnO4 was efficient to degrade PAHs in all the soil samples and the pre-heating slightly improved its efficiency. H2O2 and Fenton-like treatments presented low efficiency to degrade PAH in the soil presenting poor PAH availability, however, the PAH degradation rates were improved with the pre-heating. Consequently H2O2-based treatments (including Fenton-like) are highly sensitive to contaminant availability and seem to be valid methods to estimate the available PAH fraction in contaminated soils.

“…Electrochemical microbial biosensors are one of the most widely used platforms for microbial biosensors because of their high-sensing accuracy (D’Souza, 2001 ) and possible applications such as point-of-care testing devices (DeBusschere and Kovacs, 2001 ). Therefore, many researchers and industries have introduced electrochemical microbial biosensors that can detect many types of target materials such as glucose (Kohlmeier et al, 2008 ; Odaci et al, 2008a ), heavy metal ions (Chouteau et al, 2005 ; Guedri and Durrieu, 2008 ), phenol (Kirgöz et al, 2006 ; Neufeld et al, 2006 ), and other chemicals (Mulchandani et al, 2001 ; Tkac et al, 2003 ; Lei et al, 2006 ; Tag et al, 2007 ). Electrochemical microbial biosensors generally consist of a working electrode, a transducer layer for detection (microorganisms), and recording equipment.…”

A microbial biosensor is an analytical device with a biologically integrated transducer that generates a measurable signal indicating the analyte concentration. This method is ideally suited for the analysis of extracellular chemicals and the environment, and for metabolic sensory regulation. Although microbial biosensors show promise for application in various detection fields, some limitations still remain such as poor selectivity, low sensitivity, and impractical portability. To overcome such limitations, microbial biosensors have been integrated with many recently developed micro/nanotechnologies and applied to a wide range of detection purposes. This review article discusses micro/nanotechnologies that have been integrated with microbial biosensors and summarizes recent advances and the applications achieved through such novel integration. Future perspectives on the combination of micro/nanotechnologies and microbial biosensors will be discussed, and the necessary developments and improvements will be strategically deliberated.

“…The mechanism used for the development of biosensors is quantitative induction of the promoter gene by the target analyte; Rotariu et al ( 2002 ) thus, concentration of the analyte could be correlated with fl uorescence intensity. Using this mechanism a whole cell biosensor using Pseudomonas putida was engineered to determine the bioavailability of naphthalene (Kohlmeier et al 2008 ). A microbial biosensor using genetically engineered E. coli was developed for measuring aromatic aldehydes in the aqueous systems using the same principle (Fiorentino et al 2009 ).…”
