<i>Bacillus siamensis</i> CCT8089: a novel phosphate-solubilizing bacterium enhancing maize and soybean growth.

ABSTRACT: Phosphorus (P) is an essential macronutrient for plant growth, but its availability in tropical soils is limited due to fixation by iron and aluminum oxides. This study aimed to characterize the Bacillus siamensis CCT8089 strain in vitro, evaluating its phosphate-solubilizing and plant growth-promoting abilities and its agronomic potential in maize and soybean crops. In vitro, CCT8089 tolerated osmotic stress, produced exopolysaccharides and biofilm, and demonstrated compatibility with commercial inoculants (Azospirillum brasilense and Bradyrhizobium japonicum). The strain also exhibited biocontrol activity against Macrophomina phaseolina and Sclerotinia sclerotiorum. CCT8089 produced organic acids, particularly malic and acetic acid in Ca
