본 연구에서는 경기도 궁평항 지역의 해안사구에 서식하고 있는 토착식물 6종(Rorippa islandica, Rumex crispus, Artemisia princeps var. orientalis, Lilium sp Stellaria media, and Gramineae)의 식물 뿌리와 근권토양으로부터 colony library를 구축하여 식물성장촉진 능력과 내염능을 평가하였다. 분리한 근권세균 중 4.0%의 염분이 존재하는 환경에서50% 이상의 세균이 염분에 강한 내성을 가지고 있었다. 95개의 균주를 대상으로 식물성호르몬인 IAA생산능을 가지는균주는 근권토양에서는 13.9%, 식물뿌리에서는 7.6%였으며 1-aminocyclopropane-1-carboxylic acid (ACC)를 제거하는ACC deaminase 활성을 가진 균주는 근권토양에서는 55.8%, 뿌리에서는 36.6%였다. 또한, Siderphores 합성능을 가지고있는 균주는 근권에서 62.7%, 뿌리에서는 50%를 차지하였다. 식물성장촉진능과 내염능을 가진 세균을 대상으로 상관관계를 분석한 결과, ACC deaminase 활성과 siderphore(s)합성능 사이에는 양의 상관관계를 형성하였고(r=0.605, p<0.037), 염분 내성능과 ACC deaminase 활성, 염분 내성능과 siderphore(s) 합성능 사이에도 양의 상관관계를 형성하였다(r=0.762, p<0.004, r=0.771, p<0.003, 각각).
Coastal sand dunes are important for ecosystems due to the variety of rare species that can be found in this kind of habitat, and the beautiful landscapes they create. For environmental remediation, a potential strategy is phytoremediation using the symbiotic relationship of plants and microbes in the rhizosphere, which has proven ecologically sound, safe, and cost effective. Ninety-five colonies were isolated from the rhizosphere soil (RS) or rhizoplane (RP) of Rorippa islandica, Rumex crispus, Artemisia princeps var. orientalis, Lilium sp Stellaria media, and Gramineae. These colonies were then tested for plant growth promoting activities (PGPAs) such as 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, and siderphores synthesis ability. In addition, salt tolerance was evaluated at 4% and 8% salt concentrations. It was observed that amongst the test subjects about 50% of the strains had a high resistance to salinity. Many of them could produce indole-3-acetic acid (IAA)IAA (in RS 13.9% and in RP 7.6%), exhibited ACC deaminase activity (55.8% in RS and 36.6% in RP), and could synthesize siderphores (62.7% in RS and 50% in RP). Correlation coefficient analyses were carried out for the three kinds of plant growth promoting abilities (PGPA) and salt tolerance. A positive correlation was found between an ability to synthesize siderphores and ACC deaminase activity (r=0.605, p<0.037). Similarly, positive correlations were noted between salt tolerance and ACC deaminase activity (r=0.762, p<0.004, r=0.771), and salt tolerance and an ability to synthesize siderphores (r=0.771, p<0.003).
