Notes:
The ability to produce volatile sulfides by 41 lactobacilli was not associated with species but depended on the composition of the media and the sensitivity of the indicator. Only a restricted number of L. plantarum strains and seven isolates were H2S-positive on peptone iron, TSI and SIM agars. Lead acetate agar detected a greater number of H2S-positive lactobacilli but the lead acetate (or DTNB) paper method was superior in a modified motility sulfide broth. Cured meat agar detected the production of greening by H2CO2-producing lactobacilli (L. fructovorans, L. jensenii, L. lactis, L. viridescens, F-74, F-99). Such tests, however, were not applicable to detect lactobacilli producing green sulfmyoglobin.
