“…Jaibangyang et al (2020) identified Candida nivariensis DMKU-CE18 as an effective VOC-producing (mainly pentan-1-ol) yeast against the growth and conidial germination of Aspergillus flavus. Moreover, Jaibangyang et al (2021) revealed that Kwoniella heveanensis DMKU-CE82-produced VOCs induced conidia structural damage, inhibited mycelia and conidiophore development, and reduced aflatoxin B1 (AFB1) production to less than 20 ppb in A. flavus contaminated corn grains. The major VOCs produced by K. heveanensis DMKU-CE82 were closely matched to 3-methylbutan-1-ol, 2-methylbutan-1-ol, 1,1-dimethylhydrazine, and 3-methylbutanoic acid.…”

The fungal decay of fresh fruits and vegetables annually generates substantial global economic losses. The utilization of conventional synthetic fungicides is damaging to the environment and human health. Recently, the biological control of post-harvest fruit and vegetable diseases via antagonistic microorganisms has become an attractive possible substitution for synthetic fungicides. Numerous studies have confirmed the potential of volatile organic compounds (VOCs) for post-harvest disease management. Moreover, VOC emission is a predominant antifungal mechanism of antagonistic microorganisms. As such, it is of great significance to discuss and explore the antifungal mechanisms of microbial VOCs for commercial application. This review summarizes the main sources of microbial VOCs in the post-harvest treatment and control of fruit and vegetable diseases. Recent advances in the elucidation of antifungal VOC mechanisms are emphasized, and the applications of VOCs produced from antagonistic microorganisms are described. Finally, the current prospects and challenges associated with microbial VOCs are considered.

“…Aspergilus flavus is a common saprophytic fungus, which can colonize a range of economically important crops [ 1 ]. In addition to causing great economic losses, the contamination of food and feed by A. flavus also causes public health concerns because this fungi can produce mycotoxins (aflatoxin) [ 2 , 3 ].…”

Aspergilus flavus is the main pathogenic fungus that causes food mold. Effective control of A. flavus contamination is essential to ensure food safety. The lipopeptides (LPs) produced by Bacillus strains have been shown to have an obvious antifungal effect on molds. In this study, an antagonist strain of Bacillus velezensis with obvious antifungal activity against A. flavus was isolated from the surface of healthy rice. Using HPLC-MS analysis, the main components of LPs produced by strain E2 were identified as fengycin and iturins. Further investigations showed that LPs could inhibit the spore germination, and even cause abnormal expansion of hyphae and cell rupture. Transcriptomic analyses showed that some genes, involved in ribosome biogenesis in eukaryotes (NOG1, KRE33) and aflatoxin biosynthesis (aflK, aflR, veA, omtA) pathways in A. flavus were significantly down-regulated by LPs. In conclusion, this study provides novel insights into the cellular and molecular antifungal mechanisms of LPs against grain A. flavus contamination.

“…Various strains of epiphytic and endophytic yeasts have been reported for their ability to produce VOCs that have potential effects on phytopathogenic fungi. For example, Kwoniella heveanensis DMKU-CE82, an endophyte isolated from corn leaf tissues, produced VOCs closely matched to 2-methyl-1-butanol, 3-methyl-1-butanol, hydrazine-1-1-dimethyl, and butanoic acid-3methyl that were active against A. flavus [9,16]. Candida intermedia C410 isolated from a healthy strawberry leaf produced 1,3,5,7-cyclooctatetraene and 3-methyl-1-butanol as the most abundant compounds that had an effect against Botrytis fruit rot [17].…”

“…Most of these investigations focused on direct application of yeast cultures to agricultural products. However, when it comes to post-harvest treatment of commodities such as rice, maize, or wheat, it is necessary to consider the moisture content [9]. To circumvent this constraint, VOCs produced by microorganisms that may act against phytopathogenic fungi have been extensively investigated.…”

Aureobasidium sp. DMKU-PAL144, Rhodotorula sp. DMKU-PAL99, and Solicococcus keelungensis DMKU-PAL84. VOCs produced by these microorganisms ranged from 4 to 14 compounds and included alcohols, alkenes, aromatics, esters and furans. The major VOCs produced by the closely related Aureobasidium strains were found to bedistinct. Moreover, 2-phenylethanol was the most abundant compound generated by Aureobasidium sp. DMKU-PAL120, while methyl benzeneacetate was the major compound emitted from Aureobasidium sp. DMKU-PAL144. On the other hand, 2-methyl-1-butanol and 3-methyl-1-butanol were significant compounds produced by the other three genera. These antagonists apparently inhibited A. flavus sporulation and mycelial development. Additionally, the reduction of the AFB 1 in the fungal-contaminated rice grains was observed after co-incubation with these VOC-producing strains and ranged from 37.7 ± 8.3% to 60.3 ± 3.4%. Our findings suggest that these same microorganisms are promising biological control agents for use against aflatoxin-producing fungi in rice and other agricultural products.
