ProteomicsDeep-sea in situ and laboratory proteomics provide insights into the sulfur metabolism characteristics of a novel deep-sea bacterium, Pseudodesulfovibrio serpens sp. nov.
Sulfate-reducing bacteria (SRB) are ubiquitously distributed across various biospheres and play key roles in global sulfur and carbon cycles. However, few deep-sea SRB have been cultivated and studied in situ, limiting our understanding of the true metabolism of SRB in the deep biosphere. Here, we f...

ProteomicsCultivation and characterization of a novel clade of deep-sea Chloroflexi: providing a glimpse of Chloroflexi involved in sulfur cycling
The deep marine subsurface is one of the largest unexplored biospheres on Earth, where members of the phylum Chloroflexi are abundant and globally distributed. However, the deep-sea Chloroflexi have remained elusive to cultivation, hampering a more thorough understanding of their metabolisms. In th...

ProteomicsThiosulfate oxidation in Erythrobacter flavus 21-3 provides novel clues to the source of element sulfur in the deep-sea cold seep
Zero-valent sulfur (ZVS) and thiosulfate are important intermediates in the biogeochemical cycle of sulfur. The former has been proved to be existed in the cold seep and hydrothermal systems. Three thiosulfate oxidation pathways are already identified and here we found a novel one in Erythrobacter, ...

ProteomicsLight and polyphosphate kinase 2 cooperatively regulate the production of zero-valent sulfur in a deep-sea bacterium.
The existence of light in various deep-sea environments has been well established. Our previous research found blue light promotes zero-valent sulfur (ZVS) production in Erythrobacter flavus 21-3, a bacterium isolated from the deep-sea cold seep. E. flavus 21-3 can convert thiosulfate to ZVS through...

ProteomicsThreonine dehydratase couples L-cysteine metabolism to cadmium resistance in Pseudomonas stutzeri 273 through cadmium sulfide nanoparticle biomineralization
Cysteine is an amino acid containing sulfhydryl (-SH) group which is the basis of cysteine involved in sulfur metabolism and heavy metal detoxification in microorganisms. Here, we demonstrate that adding L-cysteine significantly improves the cadmium resistance and removal ability of Pseudomonas stut...

The prognosis of liver cancer was inferior among tumors. New medicine treatments are urgently needed. In this study, a novel exopolysaccharide EPS364 was purified from Vibrio alginolyticus 364 which was isolated from South China Sea cold seep. Further research suggested that EPS364 consisted of mann...

Metabolomicsthe intracellular flow of hexadecane in J31 cells

To investigate the metabolism and bioconversion of hexadecane in J31 cells, 13C-labeled hexadecane was added to the OM medium, and the intracellular flow of hexadecane in J31 cells was analyzed using the stable isotope technique via non-target metabolomics. study abstract/description
