Veillonella alcalescens ATCC 17745, a strictly anaerobic, gram-negative small coccus, requires putrescine or cadaverine for growth (M. B. Ritchey, and E. A. Delwiche, J. Bacteriol. 124:1213-1219, 1975). Both putrescine and cadaverine were demonstrated to be incorporated exclusively into the peptidoglycan layer of V. alcalescens ATCC 17745. V. parvula GAI 0574 also proved to contain putrescine as a component of peptidoglycan. The primary chemical structure of the peptidoglycan common to the two Veillonella species is N-acetylglucosamine-N-acetylmuramic acid-L-alanine-D-glutamic acid gamma-meso-diaminopimelic acid-D-alanine. Putrescine or cadaverine links covalently to the alpha-carboxyl group of the D-glutamic acid residue of the peptidoglycan is necessary for normal cell growth. In V. alcalescens ATCC 17745, above 40% saturation at cadaverine linked to the alpha-carboxyl group of the D-glutamic acid residue of the peptidoglycan is necessary for normal growth.
产碱韦荣球菌ATCC 17745是一种严格厌氧的革兰氏阴性小球菌，生长需要腐胺或尸胺（M. B. 里奇和E. A. 德尔维奇，《细菌学杂志》124:1213 - 1219，1975年）。已证明腐胺和尸胺都仅被整合到产碱韦荣球菌ATCC 17745的肽聚糖层中。小韦荣球菌GAI 0574也被证明含有腐胺作为肽聚糖的组成成分。这两种韦荣球菌共有的肽聚糖的主要化学结构是N - 乙酰葡糖胺 - N - 乙酰胞壁酸 - L - 丙氨酸 - D - 谷氨酸 - γ - 内消旋二氨基庚二酸 - D - 丙氨酸。腐胺或尸胺与肽聚糖中D - 谷氨酸残基的α - 羧基共价连接对于正常细胞生长是必需的。在产碱韦荣球菌ATCC 17745中，肽聚糖中与D - 谷氨酸残基的α - 羧基相连的尸胺饱和度高于40%对于正常生长是必需的。
