ABSTRACT:
The invention relates to new Streptococcus thermophilus strains containing genes giving the bioluminescence property. The strains can be applied widely for analytical purposes, e.g. in the determination of bacteriophages and antibiotics, especially from liquid samples. The invention also relates to a test set containing a bioluminescent Streptococcus thermophilus strain, and to processes for the determination of bacteriophages or antibiotics from a liquid sample.
