A new rapid biosensor method employing the dye resazurin as an indicator of bacterial respiration has been developed to provide a rapid, facile and specific biosensor for environmental contaminants that does not rely on genetic modification techniques, is suitable for a high-throughput multiwell format, and is ideally suited to resource-constrained(More)
The genus Pseudomonas contains fast-growing nutritionally versatile bacteria that are able to utilize a wide variety of carbon sources. The ubiquity of the genus has been highlighted by conventional microbiology and the genus is well represented in collections of cultured bacteria. Here we evaluate the Pseudomonas population in New Zealand soils by(More)
An in vivo enzyme-based biosensor platform was developed that uses specific oxygenase enzymes to detect aromatic compounds in water. Bacteria capable of degrading highly reduced hydrocarbons initiate substrate oxidation using well-characterised oxygenase enzymes, which due to their specificity, stability and high activity can be applied in vivo as biosensor(More)
