Two different groups of methanol-utilizing bacteria were studied by electron microsocpy. Bacteria using the serine pathway for the assimilation of methanol were found to have a thin cell envelope (outer membrane, periplasmic area and cytoplasmic membrane). Those using the assimilatory ribulose monophosphate pathway of formaldehyde fixation had a much thicker cell envelope and in the case of Pseudomonas C protrusions of the outer membrane were found.
通过电子显微镜对两组不同的利用甲醇的细菌进行了研究。发现利用丝氨酸途径同化甲醇的细菌具有薄的细胞包膜（外膜、周质区域和细胞质膜）。那些利用同化性磷酸核糖途径固定甲醛的细菌具有厚得多的细胞包膜，并且在假单胞菌C的情况下，发现了外膜的突起。
