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 6

The action of VOCs on Agrobacterium tumefaciens C58, Synechococcus sp. PCC 7942, and Rhizoctonia solani. All experiments were repeated three to four times, with two to three plates per variant. Total number of repetitions for each variant is indicated in parentheses.
