Dataset on collecting volatile compounds produced by three bacteria and testing their efficacy against the pathogen Peronophythora litchii

摘要

This data article provides supporting information to a related research article “Identification of volatile organic compounds for the biocontrol of postharvest litchi fruit pathogenPeronophythora litchii” (Zheng et?al., 2019) [1]. The litchi downy blight (LDB) caused byPeronophythora litchiiis a major postharvest disease that can severely damage litchi trees and harvested litchi fruit. This data article describes the analysis of volatile compounds (VOCs) in three bacterial biological control agents (BCAs) of LDB (Bacillus amyloliquefaciensPP19,Bacillus pumilusPI26, andExiguobacterium acetylicumSI17) via gas chromatography/mass spectrometry (GC–MS). Volatile compounds produced by the three BCAs were captured at five culture time of 24, 36, 48, 60 and 72 h by a solid-phase micro extraction method. The chemical compositions were identified and their retention times as well as relative peak areas were analyzed. Compounds commonly produced at more than one time points were then subjected toin?vitro(on petri dish) andin?vivo(litchi fruit and leaves) evaluations for their antagonistic activities against the pathogenPeronophythora litchii.
