Summary: The antimicrobial peptide produced by Bacillus velesensis P34 has potential as a natural food preservative against Gram-positive bacteria. Nanocapsules containing the peptide were produced using different polymers, and only the P34-EUD NCs showed activity against L. monocytogenes in synthetic media. However, in milk, the P34-EUD NCs did not inhibit L. monocytogenes growth, possibly due to the formation of a protein corona caused by the interaction of casein proteins with the NCs surface.

Summary: Active films based on different biopolymers, including pectin, Brea gum, carboxymethylcellulose, and composite starch-gelatin, were prepared and incorporated with lipopeptides as antimicrobial agents. The antibacterial activity of these functionalized films was dependent on the polymeric matrix and the pathogen studied. Pectin and starch-gelatin composite exhibited strong inhibitory effects against various strains, making them effective carriers for antimicrobial active films in food preservation.

Summary: The plant pathogenic bacterium Xanthomonas campestris pv. campestris (Xcc) was identified as a pathogen of winter oilseed rape in Serbia. A metabarcoding approach was used to study changes in bacterial community composition in the phyllosphere and rhizosphere of different winter oilseed rape types infected with Xcc. Indigenous Bacillus and Pseudomonas isolates were found to have potential in suppressing Xcc. The biocontrol strains Bacillus velezensis X5-2, Bacillus megaterium X6-3, and Pseudomonas orientalis X2-1P were effective against Xcc both in vitro and in vivo, showing promising results for further studies on the biocontrol of bacterial blight-like disease in oilseed rape caused by Xcc.

Summary: This study identified Bacillus velezensis C16 as a strain with strong antifungal activity against early blight pathogen Alternaria solani. The non-volatile lipopeptides and volatile organic compounds produced by C16 showed significant antagonistic activities on A. solani, leading to structural destruction of hyphae and inhibited conidia germination. High-performance liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry analysis revealed iturins and volatile compounds of C16 exhibit strong antagonistic activity on mycelia, suggesting a synergistic effect to resist early blight in potato.

Summary: Lipopeptides produced by Bacillus subtilis have various activities and can be dried using spray-drying method without compromising their antimicrobial and biosurfactant properties. The choice of purification step affects the performance of spray-drying and the purity of the obtained powder, with mycosubtilin concentration influencing the spray-drying yield.

Summary: Most biosurfactants are currently produced using expensive culture media and purification processes, limiting their wider industrial application. This study demonstrated the potential of using cheap substrates, such as soap-derived waste glycerol, to reduce the production costs of surfactin. The surfactin produced from waste glycerol showed good stability and has potential for various biotechnological applications.

Summary: This study identified a new mycovirus infecting a strain from the Fusarium incarnatum-equiseti species complex, named as "Fusarium equiseti partitivirus 1" (FePV1). FePV1 has two dsRNA segments, with one potentially functioning as a satellite RNA of FePV1. By isolating conidia, an isogenic line free of FePV1 was obtained, which showed increased growth, biomass production, and pathogenicity on tomato compared to the original infected strain, indicating that FePV1 induces hypovirulence on its host.

Summary: The study evaluated the frequency of key alterations causing resistance in commercial wheat crops across European countries, revealing the highest frequencies in Ireland and Great Britain, with a gradual increase over the past decade. While these alterations are becoming dominant in certain regions, there is still potential to delay their selection across the wider European population, highlighting the need for the implementation of fungicide antiresistance measures.
