초록

난용성 인산염을 가용화시키는 균주를 염류직접 및 인산과다처리 재배지로부터 다수 분리하였다. 다수의 균들은 대다수가 tri-calcium phosphate의 가용화능을 가진 균주들이 었고 hydroxyapacte의 가용화능을 가진 균주가 소수있었다. 본 연구는 hydroxyapatite 가용화능을 가진 분리균주 Klebsiella sp. DA7l-1의 배양특성에 따른 난용성 인산염(hydroxyapatite, tri-calcium phosphate, aluminium phosphate), pH변화 및 배양온도에 따른 인산염의 가용화특성 등을 조사하였다 인산 가용화능은 유기산 생성과 밀접한 관련이 있다고 많이 보고되어 졌지만 아직 pH저하에 따른 인산 가용화의 정확한 기작은 확인이 되지않은 상태이며 배지내의 pH저하는 균주의 유기산 생성에 따른 것으로 사료되어진다. 조사한 결과 배양시간 12 이후부터 pH 저하를 나타냈으며 pH저하는 균생육에 영향을 미치지 않는 범위내에서 이루어졌으며 pH가 저하된 상태의 배지 조건에서 균의 생육이 계속될수록 인산가용화능이 높게 이루어졌다. 또한 DA7l-1은 초기 pH에 영향을 크게 받지 않았으며 일반 토양의 온도와 비슷한 조건의 온도에서도 가용화 능력이 뛰어난 것으로 나타났다.

To develop high effiency biofertilizer, a bacterium having ability to solubilize inorganic phosphate was isolated from cultivated soils, using a sucrose minimal agar-hydroxyapatite medium. The strain was identified as Klebsiella sp. DA7l-1, based on the physiological and biochemical properties. The activity of solubilizing inorganic phosphate of Klebsiella sp. DA7l-1 against three types of insoluble phosphate such as tri-calcium phosphate, aluminium phosphate, hydroxyapatite were quantitatively determined. The results indicated that the strain solubilized hydroxyapatite. The MPS (mineral phosphate solubilizing) conditions of Klebsiella sp. DA7l-1, were measured to determine the optimal conditions. The optimal temperature and initial pH to solubilize insoluble phosphate in sucrose minimal medium were $30^{\circ}C$ and pH 6.0, respectively.
