TABLE 1.

The volatile profile of Lysobacter capsici AZ78.

Compounds listed were at least with 10 x more abundance in samples compare to control. ^∗Heatmap of log₁₀(average peak area) of compounds at 120 h and 168 h measurements of AZ78-inoculated HS vials with NA medium. ^∗∗Compounds only detected at 168 h measurements of AZ78-inoculated HS vials with NA medium. ^aCompounds identified or annotated using Metabolite Detector Software (Hiller et al., 2009), by comparing both spectrum and RI to those of an in-house library compound entry. ^bConfidence levels of compound annotation assigned according to Blazenovic et al. (2018): 1 = confident 2D structure by comparison of spectrum and RI to standard compounds analyzed under the same chromatographic conditions, 2 = probable structure by comparison of spectrum and RI to those of NIST library or literature, 3 = possible structure or compound class by comparison of spectrum to those of known compounds in literature. ^cAverage retention index of six to seven replicates of AZ78-inoculated HS vials with NA medium from 120 h and 168 h measurements, as calculated from the experimental retention time of each VOC in relation to those of a series of n-alkanes (C8–C25) analyzed under the same chromatographic conditions. ^dAverage similarity score of six to seven replicates of AZ78-inoculated HS vials with NA medium from 120 h and 168 h measurements as calculated by Metabolite Detector software for each VOC by comparing both RI and spectrum to those of an in-house library compound entry. ^e,f,gNumber of sample replicates the VOC was detected in, to the total replicate number measured in ^e AZ78-inoculated HS vials with NA medium, ^fAZ78-inoculated NA medium from split Petri dishes and ^gPDA medium samples from split Petri dishes with AZ78-inoculated NA medium in a separate compartment. n.d = Not detected. in bold = Compounds selected to be used in bioassays against soilborne plant pathogens.
