Antifungal and other bioactive properties of the volatilome of <i>Streptomyces scabiei</i>.

ABSTRACT: Volatile compounds (VCs) produced by most host-associated bacteria remain largely unexplored despite their potential roles in suppressing microbial competitors and facilitating host colonization. This study investigated the volatilome of Streptomyces scabiei 87-22, the model species for causative agents of common scab in root and tuber crops, under culture conditions that completely inhibited fungal growth, including the phytopathogens Alternaria solani and Gibberella zeae. Bicameral assays confirmed that these effects were partially due to VCs. Using gas chromatography coupled with time-of-flight mass spectrometry, 36 VCs were unambiguously identified as products of S. scabiei 87-22 metabolic activity. These included mainly ketones and aromatic compounds (both
