Bacillus velezensis Krd-20 strain with antifungal activity was isolated from the wheat rhizosphere. This strain is used to suppress fungi of the Fusarium sp. when growing oyster mushroom (Pleurotus ostreatus). Genome assembling resulted in 44 contigs with a total length of 3939663 bp were obtained, the GC content is 46.4%.

The utilization of chemical pesticides recovers 30%-40% of food losses. However, their application has also triggered a series of problems, including food safety, environmental pollution, pesticide resistance, and incidents of poisoning. Consequently, green pesticides are increasingly seen as viable alternatives to their chemical counterparts.

Bacterial levans are biopolymers composed of fructose units linked by β-2,6 glycosidic bonds that are degradable, nontoxic and flexible, representing a green technology with significant applications across various industries. Fermented soybeans are a common source of bacteria-producing polysaccharides. In this study, KKSB4, KKSB6 and KKSB7 isolated from traditionally fermented soybean (Thua-nao), along with strain 5.

Dietary fiber in cereals is an important active substance and is believed to be beneficial to consumer health. To improve the physicochemical and functional properties of highland barley dietary fiber and the integrated utilization of highland barley, Bacillus velezensis submerged fermentation was used to treat highland barley. Soluble and insoluble dietary fibers (SDF and IDF) were isolated and their yield, proximate composition, monosaccharide compositions, physicochemical, structural and functional characteristics were investigated.

The emergence of multidrug-resistant pathogens presents a significant global health challenge, which is primarily fuelled by overuse and misuse of antibiotics. Bacteria-derived antimicrobial metabolites offer a promising alternative strategy for combating antimicrobial resistance issues. Bacillus velezensis PD9 (BvPD9), isolated from stingless bee propolis, has been reported to have antibacterial activities against methicillin-resistant Staphylococcus aureus (MRSA).

The present study investigates the natural ability of Bacillus velezensis R22 to produce 2,3-BD from two inulin-rich substrates - insoluble and soluble chicory flour. After complex optimization of the media content and process parameters by consecutive application of Plackett-Burman design and response surface methodology, the strain R22 was capable of producing 71.2 g/L (95.
