    Abstract:
    A qualitative and quantitative study has been carried out on 15 strains of the Veillonella genus, isolated in the oral cavity. Following two methods of preparation of samples for injection in a chromatograph GL, we have identified among the volatil monocarboxylic aliphatic acids from C2 to C6 the glucose fermentation products of these different strains. With the same methods, we studied in parallel these products from strains A.T.C.C. 10790-17444 (Veillonella parvula) and 17445-17446 and 17447 (Veillonella alcalescens). The results, despite the diversity of origin of all these strains, based on physiological and biochemical characteristics, confirm that volatil monocarboxylic aliphatic acids are characteristic of a genus specificity and not of a species. The presence of acetic acid, proprionic acid and iso-valeric acid was shown
