The fate of bacterial carbon in an intertidal sediment: Modeling an in situ isotope tracer experiment
We report the results of an integrated modeling and in situ isotope tracer experiment study examining the fate of bacterial carbon in an intertidal sediment. 13C-glucose was injected into the upper 10 cm of an intertidal sediment, which successfully tagged the bacterial community as evidenced by 13C enrichment of bacterial specific polar-lipid-derived fatty acids. Over a period of 4.5 months, 1...
متن کاملFate of peptidoglycan in an intertidal sediment: An in situ 13C-labeling study
We investigated the fate of peptidoglycan, a bacterial cell wall component, in sediment by 13C-labeling the bacterial community of an intertidal mudflat and subsequently tracing the fate of 13C in D-alanine (D-Ala, a bacterial biomarker specific for peptidoglycan), bacteria-specific phospholipid-derived fatty acids (PLFAs, specific for cell membranes of living bacteria), and total hydrolysable ...
متن کاملElemental sulfur coarsening kinetics
BACKGROUND Elemental sulfur exists is a variety of forms in natural systems, from dissolved forms (noted as S8(diss) or in water as S8(aq)) to bulk elemental sulfur (most stable as α-S8). Elemental sulfur can form via several biotic and abiotic processes, many beginning with small sulfur oxide or polysulfidic sulfur molecules that coarsen into S8 rings that then coalesce into larger forms: [For...
متن کامل11398: Investigation of Elemental Sulfur Corrosion Mechanisms
Sour gas wells frequently co-produce elemental sulfur which can cause catastrophic corrosion of mild steel. As producing wells become increasingly sour, the incidence of sulfur corrosion will likely increase. Despite the severity of this problem, limited mechanistic information about this process exists in the literature. The objective of this study is investigation of the corrosion mechanism i...
متن کاملToxicity of elemental sulfur for brucellae.
In previous reports we have described the toxicity of certain peptones and amino acids, particularly cystine, for brucellae (Schuhardt, Rode, Foster, and Oglesby, 1949; Schuhardt, Rode, and Oglesby, 1949). Subsequently, we found and reported that cystine per se is not toxic for these organims, and proved that the observed toxicity of autoclaved cystine is due to a heat-induced breakdown product...
