“…Later, Starkey (1938) renamed it to “ Sporovibrio desulfuricans” [ 3 ] before it was finally renamed as D. nigrificans [ 1 ]. D. nigrificans is a moderate thermophile that typically grows with fructose and glucose coupled to sulfate reduction [ 1 , 4 ]; without sulfate, only growth with fructose was observed. Utilizing sugars is rare among Desulfotomaculum species.…”

Desulfotomaculum nigrificans and D. carboxydivorans are moderately thermophilic members of the polyphyletic spore-forming genus Desulfotomaculum in the family Peptococcaceae. They are phylogenetically very closely related and belong to ‘subgroup a’ of the Desulfotomaculum cluster 1. D. nigrificans and D. carboxydivorans have a similar growth substrate spectrum; they can grow with glucose and fructose as electron donors in the presence of sulfate. Additionally, both species are able to ferment fructose, although fermentation of glucose is only reported for D. carboxydivorans. D. nigrificans is able to grow with 20% carbon monoxide (CO) coupled to sulfate reduction, while D. carboxydivorans can grow at 100% CO with and without sulfate. Hydrogen is produced during growth with CO by D. carboxydivorans. Here we present a summary of the features of D. nigrificans and D. carboxydivorans together with the description of the complete genome sequencing and annotation of both strains. Moreover, we compared the genomes of both strains to reveal their differences. This comparison led us to propose a reclassification of D. carboxydivorans as a later heterotypic synonym of D. nigrificans.

“…These results and the favourable energy release compared with the criterion both support the stoichiometry of reaction lk for the partial oxidation of glucose. Akagi and Jackson (1967) did, however, note that little «0•1 %) labelled glucose was incorporated as cell carbon, suggesting that, like the substrates set out in Table 2, glucose acts as an energy but not a carbon source; this is in contrast to the other five substrates in Table 1 which apparently supply cell carbon as well as energy. Table 2 illustrates the oxidation of five substrates which provide energy, but not cell carbon, for the growth of sulphate reducers.…”

A thermodynamic feasibility study was applied as a means of predicting suitable energy-yielding substrates for growth of sulphate-reducing microorganisms. The average free energy release per electron pair for a substrate-sulphate oxidoreduction may be more or less than the energy requirement for ATP synthesis from ADP and Pi. Substrates were divided into two groups on this thermodynamic basis and the division was shown to accord with previous experimental reports; those substrates which released an average of at least 8� 4 kcal per electron pair (35�2 kJ per electron pair) were able to support growth whilst those releasing less than 8� 4 kcal were unable to do so. It is proposed that the thermodynamic assessment could be applied to a wide range of possible substrates to predict the likelihood of their serving as sole substrates for growth of these organisms.

“…The D. nigrificans strain was cultivated on a TSI medium (Triple Sugar Iron Agar, BBL BD Biosciences Sparks) with the following composition (quantities given per 1 L of purified water): 10 g enzymatic casein hydrolysate, 10 g peptone, 5 g sodium chloride, 10 g lactose, 10 g sucrose, 1 g glucose, 0.2 g ferrous ammonium sulfate, 0.2 g sodium thiosulfate, 0.025 g phenol red, 13 g agar at a temperature of 37°C, for a period of 72 h, under anaerobic conditions, with the use of a Genbox anaer generator (bioMerieux). To obtain semiliquid medium, the primary medium was diluted three times.…”

Biocorrosion of 316LV steel used in oral cavity due to Desulfotomaculum nigrificans bacteria

Corrosion processes of metallic biomaterials in the oral cavity pose a significant limitation to the life and reliable functioning of dental materials. In this article, the influence of environment bacteria Desulfotomaculum nigrificans sulfate reducing bacteria on the corrosion processes of 316LV steel was assessed. After 14 and 28 days of contact of the material with the bacterial environment, the surfaces of the tested biomaterial were observed by means of confocal scanning laser microscopy, and their chemical composition was studied using X-Ray Photoelectron Spectrometry and a scanning transmission electron microscopy. Corrosive changes, the presence of sulfur (with atomic concentration of 0.5%) on the surface of the biomaterial and the presence of a thin oxide layer (thickness of ∼20 nm) under the surface of the steel were observed. This corrosion layer with significant size reduction of grains was characterized by an increased amount of oxygen (18% mas., p < 0.001) in comparison to untreated 316LV steel (where oxygen concentration - 10% mas.). Image analysis conducted using APHELION software indicated that corrosion pits took up ∼2.8% of the total tested surface. The greatest number of corrosion pits had a surface area within the range of 100-200 μm . © 2015 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 105B: 222-229, 2017.
