RESUMO
Nitrosomonas europaea, Nitrobacter agilis, Thiobacillus denitrificans, T. neapolitanus, and T. thioparus (all obligate autotrophic bacteria) have been grown in dialysis culture, on glucose salts media, in the absence of their specific inorganic energy source. Metabolic products for N. agilis grown on nitrite salts medium were identified as keto acids. Pyruvic acid inhibited this organism at 5 × 10−5m. Keto acids were not inhibitory for the thiobacilli grown on thiosulfate medium. However, when T. denitrificans was grown on glucose with dialysis, addition of 5 × 10−4m pyruvate inhibited growth. Thus, it appears pyruvate may be inhibitory for other autotrophs, as has been reported for T. thiooxidans.
