RESUMO
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 H2S 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 H2S 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 H2S production. Previous literature descriptions of V. alcalescens as not producing H2S are incorrect; H2S production, or the previously presumed lack of it, cannot be used as a criterion differentiating V. alcalescens from V. parvula.
