    Abstract: To understand the growth-promoting and disease-inhibiting activities of plant growth-promoting rhizobacteria (PGPR) strains, the genomes of 12 Bacillus subtilis group strains with PGPR activity were sequenced and analyzed. These B. subtilis strains exhibited high genomic diversity, whereas the genomes of B. amyloliquefaciens strains (a member of the B. subtilis group) are highly conserved. A pairwise BLASTp matrix revealed that gene family similarity among Bacillus genomes ranges from 32-90%, with 2,839 genes within the core genome of B. amyloliquefaciens subsp. plantarum (now B. velezensis). Comparative genomic analyses of B. amyloliquefaciens strains identified genes that are linked with biological control and colonization of roots and/or leaves, including 73 genes uniquely associated with subsp. plantarum (now B. velezensis) strains that have predicted functions related to signaling, transportation, secondary metabolite production, and carbon source utilization. Although B. amyloliquefaciens (now B. velezensis) strains contain gene clusters that encode many different secondary metabolites, only polyketide biosynthetic clusters that encode difficidin and macrolactin are conserved within this subspecies. To evaluate their role in plant pathogen biocontrol, genes involved in secondary metabolite biosynthesis were deleted in B. amyloliquefaciens (now B. velezensis) strain, revealing that difficidin expression is critical in reducing the severity of disease, caused by Xanthomonas axonopodis pv. vesicatoria in tomato plants. This Example defines genomic features of PGPR strains and links them with biocontrol activity and with host colonization.

    Abstract: The present disclosure provides a preparation method for liquid capsules and its application in nutritional gummies, belonging to the technical field of food processing. The preparation method for the liquid capsules provided by the present disclosure is as follows: hydrocolloid, a solvent and colorant are used to prepare a wall material, a functional substance, an additive and a dispersant are used to prepare a core material, the wall material is processed into capsule shell, and the core material is encapsulated in the capsule shell and then dried to obtain the liquid capsules. The present disclosure obtains the liquid capsules with good formability by adjusting and controlling the composition and ratio of the wall materials and core materials, which enables the liquid capsules to be effectively added to gummies syrup, thereby obtaining high-quality nutritional gummies with good stability.
