Effect of plant growth-promoting bacteria (PGPB) on the antioxidant and antibacterial activities in Chilean 'sapito' common beans.

ABSTRACT: Common beans (Phaseolus vulgaris L.) are a nutritionally valuable crop with high levels of bioactive compounds, including phenolics with antioxidant and antibacterial properties. However, the functional potential of local Chilean landraces remains underexplored. Plant growth-promoting bacteria (PGPB) can influence plant metabolism, enhancing the accumulation of secondary metabolites. This study evaluates the effect of PGPB (Bacillus proteolyticus Cyn1, Bacillus safensis Cyn2, and their consortium) on the total phenolic content (TPC), antioxidant capacity, and antibacterial activity of extracts from the Chilean landrace 'Sapito'. For this, 'Sapito' bean seeds were inoculated with individual PGPB strains and their consortium and cultivated under field conditions. Extracts from the seed coat
