Abstract: Endophytic bacteria living within the medicinal plants are increasingly recognized for their ability to support plant growth and contribute to sustainable agriculture. In present study, fifteen endophytic bacteria were isolated from healthy Aloe vera tissues and evaluated their plant growth-promoting potential. Each isolate was screened for PGP traits such as phosphate solubilization, indole-3-acetic acid (IAA) production, ammonia production, siderophore production and nitrogen fixation. The majority of isolates demonstrated at least one of these beneficial activities, and several displayed notably strong performance across multiple traits particularly in phosphate solubilization and IAA production. Among them, isolate AV11 exhibited the highest PGP efficiency across assays and was identified as Brevibacillus borstelensis by 16S rRNA gene sequencing. Hence, present study suggests that B. borstelensis can serve as an effective plant growth-promoting endophyte with potential applications in sustainable agriculture. The findings highlight the functional diversity of endophytic bacteria associated with Aloe vera and their potential role in sustainable agriculture.
