Ida, S. (Cornell University, Ithaca, N.Y.), and M. Alexander. Permeability of Nitrobacter agilis to organic compounds. J. Bacteriol. 90:151-156. 1965.-None of a variety of inorganic ions or organic compounds served as a sole energy source for the growth of Nitrobacter agilis, and the test substrates were not oxidized by either intact cells or extracts of the obligate chemoautotroph. The organic substances did not serve as sole carbon sources for the bacterium in a synthetic medium, and they failed to enhance the rate of nitrite oxidation. The organism was permeable to acetate and a number of other simple carbon compounds, however, and exogenously supplied acetate was converted to a number of products. On the basis of these findings, possible reasons are examined for the inability of the chemoautotroph to use exogenous organic compounds as energy or carbon sources.
伊达，S.（纽约州伊萨卡市康奈尔大学）和M.亚历山大。敏捷硝化杆菌对有机化合物的渗透性。《细菌学杂志》90:151 - 156。1965年。——多种无机离子或有机化合物都不能作为敏捷硝化杆菌生长的唯一能源，并且这些测试底物既不能被完整细胞也不能被专性化能自养菌的提取物氧化。在合成培养基中，这些有机物质不能作为该细菌的唯一碳源，并且它们不能提高亚硝酸盐氧化速率。然而，该生物体对乙酸盐和其他一些简单碳化合物具有渗透性，外源供应的乙酸盐会转化为多种产物。基于这些发现，研究了化能自养菌无法利用外源有机化合物作为能源或碳源的可能原因。
