Antifungal Activity of Volatile Organic Compounds from Bacillus velezensis CE 100 against Colletotrichum gloeosporioides

Colletotrichum gloeosporioides is the most prevalent phytopathogen, causing anthracnose disease that severely affects production of various fruit trees, including walnut and jujube. In this study, volatile organic compounds (VOCs) from Bacillus velezensis CE 100 disrupted cell membrane integrity C. reduced spore germination by 36.4% mycelial growth 20.0% at a bacterial broth concentration 10%, while control group showed no antifungal effect. Based on headspace solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS) analysis, seven VOCs were identified B. 100. Out VOCs, 5-nonylamine 3-methylbutanoic acid only detected in but not group. Both significant activity against gloeosporioides. Treatment with µL/mL suppressed 10.9% 30.4% 14.0% 22.6%, respectively. Therefore, are potential emitted 100, first report about
