Immobilization as a technical possibility for long-term storage of bacterial biosensors.

Abstract

For applications in field experiments, the recombinant strain Salmonella typhimurium TA1535 was immobilized to permit its immediate utilization after long storage periods. Salmonella typhimurium TA1535 cells contain the plasmid that has an inducible SOS promoter fused to a promoterless luxCDABFE operon from Photobacterium leiognathi. The induction of… (More)
