Activity of the succinic dehydrogenase system was studied in Bacillus subtilis utilizing combined techniques of cytochemistry and electron microscopy. Organisms were incubated in a medium containing tetranitro-blue tetrazolium (TNBT) which served as an electron acceptor. Enzymatic activity, as evidenced by deposition of TNBT-formazan, was found on membranous organelles associated with the cytoplasmic membrane and septal plasma membrane, the nuclear area, and the plasma membrane. Flagella, approximately 190 A in diameter, with thorn-like projections protruded through the cell wall. Tangential-oblique sections of the cell wall showed many pores approximately 220 A in diameter with a center-to-center spacing of approximately 450 A.
利用细胞化学和电子显微镜相结合的技术,对枯草芽孢杆菌中的琥珀酸脱氢酶系统活性进行了研究。将生物体在含有四硝基蓝四唑(TNBT)的培养基中培养,TNBT作为电子受体。通过TNBT-甲臜的沉积证明,酶活性存在于与细胞质膜和隔膜质膜、核区域以及质膜相关的膜性细胞器上。直径约190埃的鞭毛带有刺状突起,穿过细胞壁伸出。细胞壁的切向斜切面显示出许多直径约220埃的孔,中心间距约为450埃。
