Title:
BIOSENSOR WITH THE USE OF PIGMENT-SYNTHESIS GENE OF PURPLE NON-SULFUR BACTERIUM AND METHOD OF CONSTRUCTING THE BIOSENSOR
Document Type and Number:
WIPO Patent Application WO/2006/022235
Kind Code:
A1
Abstract:
It is intended to provide a biosensor whereby measurement can be performed by a more convenient procedure and a specific chemical can be economically and visually detected. Namely, a biosensor for detecting a specific chemical comprising a recombinant purple non-sulfur bacterium which carries a sensor vector having been transferred into a pigment mutant of a purple non-sulfur bacterium with the deletion of a gene encoding spheroidene monooxygenase, characterized in that, in the sensor vector as described above, an inductive promoter showing a specific response to the specific chemical is connected in an operable matter in the upstream of thegene encoding spheroidene monooxygenase.
