“…Iturin and surfactinare metabolites secreted by Bacillus species, such as B. amyloliquefaciens (Arrebola et al., 2010), B. subtilis (Xiao et al., 2021), and B. velezensis (Asaturova et al., 2022) and have strong antifungal activity. Iturin family antibiotics have been extensively investigated for their biocontrol efficacy, comprising heptapeptides and fatty acid chains with 14–17 carbon atoms.…”

Malt produced from barley contaminated with Fusarium graminearum can cause premature yeast flocculation (PYF) in beer fermentation, which ultimately affects the production efficiency and flavor quality of beer. In this study, a strain of Bacillus velezensis B‐3 that was isolated from soil displayed strong antifungal activity against F. graminearum. The antifungal substances were extracted and separated by ammonium sulfate fractional precipitation and semipreparative high‐performance liquid chromatography to obtain fraction VI with the strongest antifungal activity. Ultra‐performance liquid chromatography‐quadrupole‐time‐of‐flight‐mass spectrometry was used to identify that the fraction contained lipopeptides such as iturin A, surfactant B, and surfactant C. The minimum inhibitory concentration of the fraction was 0.2 mg/mL, and confocal laser scanning microscopy showed that the morphology of F. graminearum hyphae was obviously abnormal, with most of them were dead. Antifungal fraction VI could inhibit the growth of F. graminearum and avoid the production of PYF factor during malting but did not affect other qualities of malt. Therefore, the development of antimicrobial agents against Fusarium provides an effective potential strategy to control the production of PYF factors for malt‐manufacturing enterprises.Practical ApplicationAntifungal fraction VI could inhibit the growth of F. graminearum and the formation of DON during malting but did not affect other qualities of malt. The levels of soluble nitrogen, free amino nitrogen, and color experienced a substantial reduction compared to the malt infected by F. graminearum. The PYF phenomenon was significantly improved, the number of suspended yeast cells and the degree of fermentation were increased, and the level of residual extract in the wort was low, close to that of control malt.

Pathogen infections on crops can lead to huge economic losses but biocontrol, an environmentally friendly approach, can be used to control infections. For the biological management of potato scab disease and better tuber quality, we assessed the possible use of Bacillus velezensis as a biocontrol agent. B. velezensis K-9 inhibited up to 44.90% of infection by Streptomyces scabies, the causative agent of potato scab. Treatment of the S. scabies infected potato with B. velezensis K-9 resulted in a significant reduction in the depth of the disease lesions compared to untreated infected potato. Using a radish seedling test, B. velezensis K-9 culture and cell-free filtrate significantly reduced (P < 0.05) potato scab disease symptoms suggesting that strain K-9 was able to reduce S. scabies pathogenesis on potato. In a field test, the disease index and the scab index for B. velezensis K-9 against potato scab were significantly different from the control. In 2021, potato yields for the B. velezensis K-9 treated plants were 12.44% higher than the control. In 2022, the potato yields following B. velezensis K-9 treatment increased by 12.65% compared to the control. In conclusion, B. velezensis K-9 prevented potato scab and also increased potato yield. Thus, B. velezensis K-9 is substantially reduced potato scab and could be used as a potential biocontrol agent for the management of soil-borne diseases of potatoes.
