本文报道了一组新的能降解草酸的厌氧细菌。新属和新种，产草酸杆菌，是人类和其他动物瘤胃和大肠的居民，它们破坏草酸的作用可能对宿主相当重要。从绵羊瘤胃，猪盲肠和人粪便中分离的菌株都是相似的革兰氏阴性，专性厌氧杆菌，但细胞脂肪酸组成和血清学反应的菌株之间的差异。用模式菌株OxB进行的测量表明，消耗1摩尔质子/摩尔草酸盐降解产生apx。1摩尔CO2和0.9摩尔甲酸盐。没有发现取代草酸盐作为生长基质的物质。
This report describes a new group of anaerobic bacteria that degrade oxalic acid. The new genus and species, OXALOBACTER formigenes, are inhabitants of the rumen and also of the large bowel of man and other animals where their actions in destruction of oxalic acid may be of considerable importance to the host. Isolates from the rumen of a sheep, the cecum of a pig and from human feces were all similar gram-negative, obligately anaerobic rods, but differences between isolates in cellular fatty acid composition and in serologic reaction were noted. Measurements made with type strain OxB indicated that 1 mol of protons was consumed/mol of oxalate degraded to produce .apprx. 1 mol of CO2 and 0.9 mol of formate. Substances that replaced oxalate as a growth substrate were not found.
