Inhibitory and Toxic Effects of Volatiles Emitted by Strains of Pseudomonas and Serratia on Growth and Survival of Selected Microorganisms, Caenorhabditis elegans, and Drosophila melanogaster

Table 7

The action of individual VOCs on Drosophila melanogaster. The numbers of live flies per tube of 10 (mean ± SE ) were counted on the 5th day (3 experiments, each with 2 replicate tubes). All flies were alive in control tubes.

DMDS	3 ± 1	0	0	0
2-Nonanone	5 ± 2	3 ± 1	0	0
2-Heptanone	3 ± 1	0	0	0
