Abstract

Direct bioautography performed with luminescence gene-tagged bacteria enables almost real-time detection of antimicrobial compounds in plant extracts. This method for the detection of chamomile ( Matricaria recutita ) components with antibacterial effect against Bacillus subtilis soil bacteria was more sensitive than commonly used bioautographic visualization by staining with a tetrazolium salt. Some compounds had a strong inhibiting effect only via the bioluminescence measurement. Extraction of antibacterial components of chamomile flowers was most effective with 50% ethanol; slightly lower efficiency was achieved with acetone and methanol, and hexane was least effective. The results were confirmed by using luminescent Pseudomonas syringae pv. maculicola plant pathogen bacteria.
