摘要
膜电位对棕色固氮菌整体细胞固氮活性有调控作用。外加扫描电位能调控缺固氮酶活性中心、无固氮活性的棕色固氮菌突变菌株 CA30表达略高于天然棕色固氮菌的固氮活性。
Membrane potentials have regulating action to nitrogenase activity of whole cell from Azotobacter vinelandii.Extra scanning potentials are able to regulate mutant strain CA30 of Azotobacter vinelandii in the absence of the activecenter of nitrogenase and of the activity of nitrogen fixation to express the nitrogen fixation activity,which is somewhat higher than that of natural Azotobacter vinelandii.
