For implementing this promising technology, migration mechanism of sulfur element during the entire ST-SCW depolymerization process was identified to reduce the sulfur pollutions. In the depolymerization process of ST, OH radicals released from SCW molecules could enhance cleavage of CS bonds, resulting sulfur-containing intermediates. The intermediates could be further oxidized by free OH radicals and transformed into inorganic sulfur molecules mainly consisting of SO42-, S2O32-, SO32- and S2-. In this study, a combined ReaxFF-MD and DFT method was performed to study the detailed sulfur migration mechanism during ST depolymerization in the presence of SCW and provided a strategy to fix low-valent sulfur in aqueous solution for separation of sulfur from the oil & gas products. This work provides a guidance to make ST-SCW technology cleaner and cheaper.To explore the potential association between the diversity of endophytic microorganisms and modifications of grain quality in wheat exposed to multi-generational elevated CO2 concentration, the grain quality attributes and microbial diversity were tested after five generations successively grown in ambient CO2 concentration (F5_A, 400 μmol L-1) and elevated CO2 concentration (F5_E, 800 μmol L-1). Elevated CO2 concentration significantly increased the grain number and starch concentration, while decreased the grain protein concentration. Multi-generational exposure to elevated CO2 concentration also led to significant changes in grain amino acid concentration. In response to the elevated CO2 concentration, Pseudomonas, Rhodococcus, Ralstonia, and Klebsiella were the dominant bacterial genera, while Penicillium, Cutaneotrichosporon, Fusarium, Sarocladium, Acremonium and Aspergillus were the dominant fungal genera in wheat grain.
