Diversity Of Endophytic Growth-Promoting Bacteria Associated With Medicinal And Aromatic Species

Abstract

The aim of this study was to isolate endophytic bacteria from medicinal and aromatic plant tissues in the department of Sucre, Colombia and to evaluate plant growth promoting activity. Strains of endophytic bacteria were isolated and their plant growth promoting activity (nitrogen fixation, phosphate solubilization, siderophore and ACC-deaminase production) was evaluated in vitro. The results found the endophyte species Bacillus cereus and Burkholderia contamins of Lippia origanoides, Lippia alba and Melia azederach. These bacteria showed positive activity for nitrogen fixation, phosphate solubilization, siderophore production and ACC-deaminase. Endophyte species with plant growth-promoting capacity are associated with the medicinal plant species of L. origanoides, L. alba and M. azederach.
