| description | Plant growth-promoting rhizobacteria are known to enhance the growth and antioxidant activity of several plants. However, the effects of such rhizobacteria on <i>Geum aleppicum</i>, a plant with pharmacological potential in Korea are unknown. In this study, we investigated the effects of <i>Pseudarthrobacter</i> sp. NIBRBAC000502770 treatment (100 mL/pot, every two weeks for 55 days), in the form of culture medium, 100−fold diluted culture, culture supernatant, and pelleted cells resuspended in water, on the growth, antibacterial activity and flavonoid content of <i>G. aleppicum</i>. The NIBRBAC000502770 strain showed high indole-3-acetic acid (IAA) content of 461.81 μg∙mL<sup>−1</sup>. The dry weight of the roots was significantly higher in the supernatant, diluted culture, and pellet-treated plants compared to that in the control plants. Additionally, the plant height, root length, leaf length, leaf width, chlorophyll content, biomass, and dry weight of the shoot were highest in the pellet-treated plants. Further, methanol extracts of pellet-treated plants showed significantly high flavonoid content compared to that in the control plants (28 mg∙g<sup>−1</sup> vs. 7.5 mg∙g<sup>−1</sup>) and exhibited strong antibacterial activity against Gram-positive and negative bacteria. These results demonstrate the beneficial effects of <i>Pseudarthrobacter</i> sp. NIBRBAC000502770 on the growth and flavonoid content of <i>G. aleppicum.</i> |
