Title : Plant growth promotion and antimicrobial activity of bud endophyte Bacillus pumilus PM2 associated with ethnomedicinal plant Spilanthes acmella (L.) L. from biodiversity hotspot of Arunachal Pradesh, India

Abstract :

This study aims to identify and develop a novel inoculum of highly resistant endophytic bacteria associated with Spilanthes acmella (L.) L. from the unexplored forest rich region of the Eastern Himalayan region of Arunachal Pradesh. These bacteria can adapt to the local soil conditions and offer several benefits to plants. These isolates were obtained through surface sterilization and assessed for their ability to promote plant growth and combat fungal pathogens like Sclerotium rolfsii and Sclerotinia sclerotiorum. The most effective isolate PM2 was tested using a plant inoculation assay to measure its impact on the growth of a local rice cultivar. The antimicrobial compounds produced by this isolate were identified using Thin Layer Chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GC-MS). The isolate was further identified through 16S rRNA gene sequencing.
