Bacteriol. 88：37-41。1964.-本文介绍和讨论了105株来自不同来源的韦荣氏球菌产生H（2）S所需的条件，这些菌株包括7个抗原组。所有菌株在添加适量l-半胱氨酸、l-胱氨酸、还原型谷胱甘肽、硫代硫酸盐、硫氰酸盐或巯基乙酸盐的限定培养基中生长1 ~ 2天，均产生H（2）S。一些常用的培养基含有酵母提取物和酪蛋白消化物，但没有补充适当的H（2）S生产底物，得到不稳定或阴性结果。先前文献中关于产碱弧菌不产生H（2）S的描述是不正确的; H（2）S的产生，或先前假定的缺乏，不能用作区分产碱弧菌和小弧菌的标准。
Rogosa, Morrison (National Institute of Dental Research, Bethesda, Md.), and Ferial S. Bishop. The genus Veillonella. III. Hydrogen sulfide production by growing cultures. J. Bacteriol. 88:37-41. 1964.-The conditions necessary for H(2)S production by 105 strains of Veillonella, from a variety of sources and comprising seven anti-genic groups, are presented and discussed. All strains, during 1 to 2 days of growth, produced H(2)S in a defined medium supplemented with proper amounts of l-cysteine, l-cystine, reduced glutathione, thiosulfate, thiocyanate, or thioglycolate. Erratic or negative results were obtained with some commonly used media containing yeast extract and casein digest, but which were not supplemented with appropriate substrates for H(2)S production. Previous literature descriptions of V. alcalescens as not producing H(2)S are incorrect; H(2)S production, or the previously presumed lack of it, cannot be used as a criterion differentiating V. alcalescens from V. parvula.
