The character of changes in the infrared spectra of E. coli in the process of their mechanical disintegration has been studied. The destruction of E. coli cell structures has been shown to produce no changes in the optical density of the main analytical absorption bands in infrared spectra. This fact suggests that the infrared absorption spectra of E. coli are the sum of the spectra of all chemical components of the cell, which is confirmed by the infrared spectral study of E. coli cell-wall preparations. Similar results have been obtained in the study of the preparations of B. pertussis cell walls, protoplasts and intact cells.
研究了大肠杆菌在机械破碎过程中红外光谱的变化特征。结果表明，大肠杆菌细胞结构的破坏并未导致红外光谱中主要分析吸收带的光密度发生变化。这一事实表明，大肠杆菌的红外吸收光谱是细胞所有化学成分光谱的总和，这一点已通过对大肠杆菌细胞壁制剂的红外光谱研究得到证实。在对百日咳博德特氏菌细胞壁制剂、原生质体和完整细胞的研究中也获得了类似的结果。
