Up-regulated proteins under salt stress include an ABC transporter permease, glycerol-3-phosphate permease, pyrimidine nucleotide transporter, formate dehydrogenase, and down-regulated proteins include succinate dehydrogenase iron-sulfur subunit, flavoprotein subunit, cytochrome b-556 subunit, and a hypothetical membrane protein similar to charperone DnaJ. Some of these changes were further verified by enzyme activity assay.

盐胁迫诱导上调表达的蛋白包括ABC型转运蛋白，3-磷酸甘油透性酶，嘧啶核苷转运蛋白和甲酸脱氢酶；下调表达的蛋白包括琥珀酸脱氢酶铁硫亚基、黄素蛋白亚基、细胞色素b556亚基，以及分子伴侣DnaJ的同源蛋白，酶活力测定结果表明胁迫条件下上述蛋白的活性变化与表达量变化相一致。

根据内蒙古乌达矿区高硫煤9煤层（有机硫同位素值 d 34 S=－12.3‰~5.8‰，黄铁矿硫同位素值 d 34 S=－18.7‰~1.1‰）和低硫煤13煤层（有机硫同位素值 d 34 S 为8.9‰~ 11.5‰，黄铁矿硫同位素值 d 34 S 为8.3‰~ 9.7‰）剖面上有机硫和黄铁矿硫同位素的组成，结合煤岩学特征的综合分析以及黄铁矿化菌落和蓝藻胶壳的发现，提出了高硫煤中硫的演化模式，认为高硫煤中硫的同位素由于硫酸盐的异化细菌还原作用导致硫同位素大规模分馏，使之趋于负值。
