Effect of hydrogen sulfide on carbon sequestration by hydrogen oxidizing bacteria

The objective of this study is to explore the effects of hydrogen sulfide on the autotrophic growth, protein synthesis, and amino acid metabolism of Cupriavidus necator H16, analyze the inhibitory effects of hydrogen sulfide on HOB at different concentrations and its mechanisms, and provide theoretical support for further optimizing the application of HOB in the biogas fermentation process. Meanwhile, this study also helps to reveal the potential role of hydrogen sulfide in the microbial carbon fixation process and offers more theoretical basis for the applications of biological carbon capture and single - cell protein synthesis.
