“…Elemental sulfur is an apolar mineral, thus mass transfer is expected to be an important rate-limiting factor in the overall process. The specific surface area of elemental sulfur is a principal factor governing the kinetics of its biological oxidation (Konishi et al, 1995;Tichy et al, 1994), including oxidation linked to denitrification (Koenig and Liu, 2001). …”

Chemolithoautotrophic denitrifying microorganisms oxidize reduced inorganic sulfur compounds coupled to the reduction of nitrate as an electron acceptor. These denitrifiers can be applied to the removal of nitrogen and/or sulfur contamination from wastewater, groundwater, and gaseous streams. This study investigated the physiology and kinetics of chemolithotrophic denitrification by an enrichment culture utilizing hydrogen sulfide, elemental sulfur, or thiosulfate as electron donor. Complete oxidation of sulfide to sulfate was observed when nitrate was supplemented at concentrations equal or exceeding the stoichiometric requirement. In contrast, sulfide was only partially oxidized to elemental sulfur when nitrate concentrations were limiting. Sulfide was found to inhibit chemolithotrophic sulfoxidation, decreasing rates by approximately 21-fold when the sulfide concentration increased from 2.5 to 10.0 mM, respectively. Addition of low levels of acetate (0.5 mM) enhanced denitrification and sulfate formation, suggesting that acetate was utilized as a carbon source by chemolithotrophic denitrifiers. The results of this study indicate the potential of chemolithotrophic denitrification for the removal of hydrogen sulfide. The sulfide/nitrate ratio can be used to control the fate of sulfide oxidation to either elemental sulfur or sulfate.

“…Eq. 15 Tichý et al (1994) showed that biological elemental sulfur has a hydrophilic behavior -forming ionic bonds with other molecules -, which is a key factor for biological elemental sulfur removal. This is due to the fact that the microorganisms need to adhere to elemental sulfur to oxidize it to sulfate.…”

“…The growth of thiobacilli can be also stimulated by feeding them microbially produced elemental sulfur (Tichý et al, 1994). This sulfur is produced during biological sulfide removal from wastewater under oxygen-limiting conditions (Janssen et al, 1995).…”
