ent with normal distribution, and Spearman rank correlations have been used for illness incidence and FOC (R software Version 3.2.two).Outcomes Identification of B. amyloliquefaciens BThe bacterial strain B2, an antagonist against FOC (Figure two), was obtained from the rhizosphere soil with the cucumber. Physiological and biochemical traits are shown in Table 1. From these final results, strain B2 was affiliated for the genus Bacillus. To further determine strain B2, 16S rDNA and gyrB genes have been analyzed by sequencing. The 16S rDNA sequence on the strain B2 (GenBank accession quantity: MW308308) shared 99.8 identity with the 16S rDNA sequences of B. amyloliquefaciens (NR117946.1). The phylogenetic evaluation of 16S rDNA sequences clearly showed that the strain B2 and B. amyloliquefaciens have been clustered together (Figure 3A). Also, its gyrB gene sequence (GenBank accession quantity: MW316056) shared 99.eight identity together with the gyrB gene sequences of B. amyloliquefaciens (KC439665.1). The phylogenetic analysis of gyrB gene sequences showed that the strain B2 and B. amyloliquefaciens had been clustered with each other (Figure 3B). Hence, depending on physiological and biochemical testing, and 16S rDNA and gyrB gene sequences analyses, strain B2 was identified as B. amyloliquefaciens.Plant-Beneficial Traits of B. amyloliquefaciens BStrain B2 was tested for the presence of a number of plantbeneficial traits.

Additionally, strain B2 was discovered to be constructive for phosphate solubilization, siderophore production, and biofilm formation (Table 2). The root surfaces of cucumber seedlings that had been inoculated with strain B2 have been examined working with scanning electron microscopy (SEM) (Figure 4). Bacterial cells had been easily visible on the root surface and strongly adhered towards the root surface since the sample preparation for SEM analysis needs various treatment options and exhaustive CB1 Antagonist web washes. High-resolution images also showed bacteria-forming biofilm structures on the root surfaces (Figure four).Frontiers in Microbiology | frontiersin.orgAugust 2021 | Volume 12 | ArticleWang et al.Co-application of Bacteria and FungusFIGURE 5 | Detection on the optimum concentration of mixture of phenolic acids for P. ostreatus P5 degradation.
