Tolerance and adaptation to heavy metals of Desulfovibrio- and Desulfotomaculum-strains of different origin have been investigated in enrichment cultures under different conditions of sulphate supply. Three groups of low, medium, and high toxicity were found with As, V, and Mo in the first, Ni, Sb, Co, and Hg in the second, and Cd, Zn, U, and Cu in the third group. If the SO"4-supply was restricted to heavy metal sulphates with a relation of 1:1 of heavy metal- and SO"4 -ions (2:3 with Sb2(SO4)3) the tolerance was somewhat lowered. Adaptation to higher concentrations of heavy metals was possible, if the strains had not yet been exposed and adapted to higher concentration levels at their natural habitats. The tolerance range of desulfurizers has been compared with the tolerance range of different biochemical types of microorganisms.
在不同硫酸盐供应条件下的富集培养中，对不同来源的脱硫弧菌属和脱硫肠状菌属菌株对重金属的耐受性和适应性进行了研究。发现砷、钒和钼分为低、中、高毒性三组，第一组为砷、钒和钼，第二组为镍、锑、钴和汞，第三组为镉、锌、铀和铜。如果将硫酸根供应限制为重金属硫酸盐，且重金属离子与硫酸根离子的比例为1:1（对于硫酸锑则为2:3），则耐受性会有所降低。如果菌株尚未在其自然栖息地接触并适应更高浓度水平，那么它们有可能适应更高浓度的重金属。已将脱硫菌的耐受范围与不同生化类型微生物的耐受范围进行了比较。
