Abstract
Electrochemical biosensor holds great promise in the biomedical area due to its enhanced specificity, sensitivity, label-free nature and cost effectiveness for rapid point-of-care detection of diseases at bedside. In this review, we are focusing on the working principle of electrochemical biosensor and how it can be employed in detecting biomarkers of fatal diseases like cancer, AIDS, hepatitis and cardiovascular diseases. Recent advances in the development of implantable biosensors and exploration of nanomaterials in fabrication of electrodes with increasing the sensitivity of biosensor for quick and easy detection of biomolecules have been elucidated in detail. Electrochemical-based detection of heavy metal ions which cause harmful effect on human health has been discussed. Key challenges associated with the electrochemical sensor and its future perspectives are also addressed.

Isolation of cholesterol- and deoxycholate-degrading bacteria from soil samples: evidence of a common pathway. Appl Microbiol Biotechnol 2012; 97:891-904. [PMID: 22406861 DOI: 10.1007/s00253-012-3966-7] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2011] [Revised: 02/10/2012] [Accepted: 02/11/2012] [Indexed: 10/28/2022]
Abstract
Nineteen different steroid-degrading bacteria were isolated from soil samples by using selective media containing either cholesterol or deoxycholate as sole carbon source. Strains that assimilated cholesterol (17 COL strains) were gram-positive, belonging to the genera Gordonia, Tsukamurella, and Rhodococcus, and grew on media containing other steroids but were unable to use deoxycholate as sole carbon source. Surprisingly, some of the COL strains unable to grow using deoxycholate as sole carbon source were able to catabolize other bile salts (e.g., cholate). Conversely, strains able to grow using deoxycholate as the sole carbon source (two DOC isolates) were gram-negative, belonging to the genus Pseudomonas, and were unable to catabolize cholesterol and other sterols. COL and DOC were included into the corresponding taxonomic groups based on their morphology (cells and colonies), metabolic properties (kind of substrates that support bacterial growth), and genetic sequences (16S rDNA and rpoB). Additionally, different DOC21 Tn5 insertion mutants have been obtained. These mutants have been classified into two different groups: (1) those affected in the catabolism of bile salts but that, as wild type, can grow in other steroids and (2) those unable to grow in media containing any of the steroids tested. The identification of the insertion point of Tn5 in one of the mutants belonging to the second group (DOC21 Mut1) revealed that the gene knocked-out encodes an A-ring meta-cleavage dioxygenase needed for steroid catabolism.

Abstract
Several functional and biochemical parameters have been proposed as biomarkers of effect of environmental pollutants. A rapid biosensor working with immobilized human U-937 cells was developed and applied to environmentally relevant chemicals with different structures and toxicological pathways, i.e. benzalkonium chloride, clofibric acid, diclofenac, mercury nitrate, ofloxacin, and sodium dodecyl sulphate. Respiration of cells was relied upon as a comprehensive biochemical effect for screening purposes. Analytical parameter (DeltappmO(2)) and toxicological index (respiratory inhibition, delta%) measured after 1h of exposure were utilized for dose-response relationship study. Results (toxicity rating scales based on delta(50)% and steepness) were compared with those obtained by the same approach previously optimized on Saccharomyces cerevisiae. The toxicity rating scale obtained by the biomarker based on human mitochondrial and cell metabolic activities compared well with previous scale obtained on yeast cells and with available in-vivo acute toxicity indexes; respiration was confirmed as toxicological endpoint reliably measurable by the biosensor.

Abstract
Baker's yeast, Saccharomyces cerevisiae, is the simplest and most well-known representative of eukaryotic cells and thus a convenient model organism for evaluating toxic effects in human cells and tissues. Yeast cell sensors are easy to maintain with short generation times, which makes the analytical method of assessing antifungal toxicity cheap and less-time consuming. In this work, the toxicity of test compounds was assessed in bioassays based on bioluminescence inhibition and on traditional growth inhibition on agar plates. The model organism in both tests was a modified S. cerevisiae sensor strain that produces light when provided with D-luciferin in an insect luciferase reporter gene activity assay. The bioluminescence assay showed toxic effects for yeast cell sensor of 5,6-benzo-flavone, rapamycin, nystatin and cycloheximide at concentrations of nM to μM. In addition, arsenic compounds, cadmium chloride, copper sulfate and lead acetate were shown to be potent non-specific inhibitors of the reporter organism described here. The results from a yeast agar diffusion assay correlated with the bioluminescence assay results.

Abstract
In human liver, unconjugated bile acids can be formed by the action of bile acid-CoA thioesterases (BACTEs), whereas bile acid conjugation with taurine or glycine (amidation) is catalyzed by bile acid-CoA:amino acid N-acyltransferases (BACATs). Both pathways exist in peroxisomes and cytosol. Bile acid amidation facilitates biliary excretion, whereas the accumulation of unconjugated bile acids may become hepatotoxic. We hypothesized that the formation of unconjugated and conjugated bile acids from their common substrate bile acid-CoA thioesters by BACTE and BACAT is regulated via the peroxisome proliferator-activated receptor alpha (PPARalpha). Livers from wild-type and PPARalpha-null mice either untreated or treated with the PPARalpha activator WY-14,643 were analyzed for BACTE and BACAT expression. The total liver capacity of taurochenodeoxycholate and taurocholate formation was decreased in WY-14,643-treated wild-type mice by 60% and 40%, respectively, but not in PPARalpha-null mice. Suppression of the peroxisomal BACAT activity was responsible for the decrease in liver capacity, whereas cytosolic BACAT activity was essentially unchanged by the treatment. In both cytosol and peroxisomes, the BACTE activities and protein levels were upregulated 5- to 10-fold by the treatment. These effects caused by WY-14,643 treatment were abolished in PPARalpha-null mice. The results from this study suggest that an increased formation of unconjugated bile acids occurs during PPARalpha activation.

Abstract
Whole cell biosensors are able to provide information that sensors based on single and multiple types of molecules are unable to do. For example, broad-spectrum catabolite analysis, cell toxicity and genotoxicity are best detected in the context of a functioning cell. Most whole cell sensors have used bacterial cells as the sensing element. Fungal cells, however, can provide all of the advantages bacterial cells offer but in addition they can provide information that is more relevant to other eukaryote organisms. These cells are easy to cultivate, manipulate for sensor configurations and are amenable to a wide range of transducer methodologies. An overview of the use of yeast and filamentous fungi as the sensing element of some biosensors is presented here.

Abstract
Here we describe an alternative approach to currently used cytotoxicity analyses through applying eukaryotic microbial biosensors. The yeast Saccharomyces cerevisiae was genetically modified to express firefly luciferase, generating a bioluminescent yeast strain. The presence of any toxic chemical that interfered with the cells' metabolism resulted in a quantitative decrease in bioluminescence. In this study, it was demonstrated that the luminescent yeast strain senses chemicals known to be toxic to eukaryotes in samples assessed as nontoxic by prokaryotic biosensors. As the cell wall and adaptive mechanisms of S. cerevisiae cells enhance stability and protect from extremes of pH, solvent exposure, and osmotic shock, these inherent properties were exploited to generate a biosensor that should detect a wide range of both organic and inorganic toxins under extreme conditions.
