| abstract |
The present invention relates to a nucleic acid comprising a contiguous nucleotide sequence containing: (i) a gene encoding luxA, (ii) a gene encoding luxB, (iii) a gene encoding luxC, ( iv) a gene which codes for luxD, (v) a gene which codes for luxE, wherein each of the genes is under the control of a promoter heterologous to the respective gene, and wherein all of the genes and promoter are contained in a single nucleotide sequence lined up . The invention further relates to vectors and host cells comprising the nucleic acid. Also described are methods for producing a host cell of the invention and methods and uses for detecting an environmental impact and a corresponding kit. |
