Implication

Exploratory study uncovers dual antimicrobial and resistant profiles in edible rhizome endophytes, highlighting food safety concerns.

Key Points

To isolate and characterize endophytic bacteria from edible rhizomes to evaluate their antibacterial metabolite production alongside their antibiotic resistance profiles.
Isolated 24 endophytic bacterial strains from fresh rhizomes of ginger (Zingiber officinale), turmeric (Curcuma longa), and white radish (Raphanus sativus) using tissue segmentation.
Tested isolates for antimicrobial activity against multidrug-resistant clinical pathogens and assessed susceptibility to major antibiotic classes.
Identified active isolates via 16S rRNA gene sequencing and evaluated crude extracellular metabolites from key strains.
Eight isolates (33.33%) exhibited inhibitory activity against multidrug-resistant pathogens, including Escherichia coli, Shigella spp., and Staphylococcus aureus, with Burkholderia contaminans RD-1(b) producing broad-spectrum antibacterial metabolites.
Identified strains included Burkholderia contaminans and Enterobacter cloacae, which demonstrated multidrug resistance to β-lactams, macrolides, and tetracyclines while remaining susceptible to ciprofloxacin and cotrimoxazole.
