Journal ArticleDOI
Pathway of succinate and propionate formation in Bacteroides fragilis.
TL;DR: The results of the labeling experiments showed that propionate is formed from succinate via succinyl-, methylmalonyl-, and propionyl-coenzyme A, and it also is clear that CO(2) is necessary for growth because it is needed for the formation of C4 acids.
Journal ArticleDOI
The periplasmic nitrite reductase of Thauera selenatis may catalyze the reduction of selenite to elemental selenium
TL;DR: The nitrite reductase (or a component of the nitrite respiratory system) is involved in catalyzing the reduction of selenite to elemental selenium while also reducing nitrite.
Journal ArticleDOI
Selenate reduction by a Pseudomonas species: a new mode of anaerobic respiration.
TL;DR: Two organisms have been newly isolated which do this in anaerobic coculture, one of which reduces selenite to elemental selenium and the other, a Pseudomonas species, was shown to respire selenate to selenites.
Journal ArticleDOI

TL;DR: Widespread use of this system could reduce the amount of selenium deposited in the San Joaquin River from 7,000 to 140 lb/year and Nalmet 8072, a new, commercially available precipitant-coagulant is described.
Journal ArticleDOI
Growth the Wolinella succinogenes on H2S plus fumarate and on formate plus sulfur as energy sources
TL;DR: Wolinella succinogenes was found to grow on H2S plus fumarate with the formation of elemental sulfur and succinate, and the growth rate was 0.18 h-1 (tcffffd=3.8 h) and the estimated growth yield was estimated to be 6.0 g per mol Fumarate used.
