The Microbial Sulfur Cycle
pathways in sequenced Chlorobi are examined. Finally, the latest developments in microbial pathways for the degradation of DMSP, an extremely important component of the marine sulfur cycle are summarized. Three research articles focus on the regulation of sulfur oxidation genes in the purple sulfur bacterium Allochromatium vinosum, growth on tetrathionate vs. S(0) in Acidithiobacillus caldus an...
متن کاملPleistocene sediment offloading and the global sulfur cycle
Quaternary sea level fluctuations have greatly affected the sediment budgets of the continental shelves. Previous studies suggested that this caused a considerable increase in the net loss of shelf sediments. Since sediment accumulation and erosion are closely tied to the formation and re-oxidation of pyrite, we use a high-resolution record of sulfur isotope ratios (S / S) of marine sulfate to ...

(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...
متن کاملSulfur isotope variability of oceanic DMSP generation and its contributions to marine biogenic sulfur emissions.
Oceanic dimethylsulfoniopropionate (DMSP) is the precursor to dimethylsulfide (DMS), which plays a role in climate regulation through transformation to methanesulfonic acid (MSA) and non-seasalt sulfate (NSS-SO(4)(2-)) aerosols. Here, we report measurements of the abundance and sulfur isotope compositions of DMSP from one phytoplankton species (Prorocentrum minimum) and five intertidal macroalg...
متن کاملThe Evolution of the Sulfur Cycle
There are 2 principal avenues of inquiry relevant to reconstructing the history of the sulfur cycle. One avenue relies on the comparison of molecular sequences derived from biologically essential proteins and genetic material. Most sequence information is available from the small subunit of the rRNA molecule and from these sequences a Tree of Life emerges providing a reconstruction of the evolu...
