Isolation and Identification of a Growth-promoting and Aluminum-resistant Endophytic bacterium from Tea Tree
摘要
Abstract
Fifty three aluminum-resistant endophytic bacteria were isolated from the healthy tissues of a tea tree.Among those strains,the G3 strain was selected for further studding based on the evaluation of its growth-promoting capabilities .This strain exhibited remarkable plant-growth-promoting properties including phosphate solubilization activity ,production of phytohormone ,nitrogen fixation ,siderophore biosynthesis and 1-aminocyclopropane-1-carboxylate deaminase activity .Moreover ,the G3 strain was also proved to facilitate seed germination and seedling growth of wheat .The 16S rDNA sequence analysis suggested that the G 3 strain was a species of Burkholderia sharing a sequence similarity of 99%with Burkholderia cepacia.In addition ,the experi-ment results of aluminum ion adsorption showed that the G 3 strain got its optimum adsorption activity at pH 5.0 and 30 ℃and the adsorption equilibrium time was about 1 hour .关键词
