Direct application of high-sulfur fuels and ores can cause environmental pollution (such as air pollution and acid rain) and, in serious cases, endanger human health and contribute to property damage. In the background of preserving the environment, microbial desulfurization technologies for high-sulfur fuels and ores are rapidly developed. This paper aims to reveal the progress of microbial desulfurization research on fuels and ores using bibliometric analysis. 910 publications on microbial desulfurization of fuels and ores from web core databases were collected in this work, spanning 39 years. Through 910 retrieved documents, collaborative networks of authors, institutions and countries were mapped by this work, the sources of highly cited articles and cited documents were statistically analyzed, and keyword development from different perspectives was discussed. The results of the study provide a reference for microbial desulfurization research and benefit environmental protection and energy green applications.

High salinity, low fertility and poor structure in saline-alkali soils led to nutrient cycling slow and microbial activity loss. The application of amendments has proven effective in enhancing soil nutrients, which significantly affects soil nitrogen and phosphorus cycling process. However, the specific impact of different amendments on the microbial functional potential related to nutrient cycling in saline-alkali soils remains unclear.

This study focuses on the coupled process of bio-enhanced absorption and biodesulfurization for the toxic gas HS and the greenhouse gas CO. The results show that on the basis of stabilized absorption of HS and CO by alkaline solution (Stage I), the addition of air-lift bioreactor process solution in the absorption column enhanced their absorption (Stage II). Specifically, at constant inlet concentrations of H₂S and CO₂ of 3% (30,000 ppmv) and 30% (300,000 ppmv), respectively, the outlet gases were primarily H₂S, CO₂, and N₂.

Saline-alkali soils have poor N storage capacity, high N loss and inadequate nutrient supply potential, which are the main limiting factors for crop yields. Vermicompost can increase organic nutrient content, improve soil structure, and enhance microbial activity and function, and the Ca in flue gas desulfurization (FGD) gypsum can replace Na and neutralize alkalinity in saline-alkali soils though chemical improvement. This study aimed to determine if vermicompost and FGD gypsum addition could improve the N storage capacity through decreasing NH volatilization and N/NO leaching from saline-alkali soils.
