Abstract

Cocultures of Desulfovibrio desulfuricans and Methanococcus maripaludis grew on sulfate-free lactate medium while vigorously methylating Hg2+. Individually, neither bacterium could grow or methylate mercury in this medium. Similar synergistic growth of sulfidogens and methanogens may create favorable conditions for Hg2+ methylation in low-sulfate anoxic freshwater sediments.

摘要

脱硫脱硫弧菌和沼泽甲烷球菌的共培养物在无硫酸盐的乳酸盐培养基上生长，同时能高效地将Hg2+甲基化。单独培养时，这两种细菌在该培养基中均无法生长或使汞甲基化。硫化物生成菌和产甲烷菌的类似协同生长可能为低硫酸盐缺氧淡水沉积物中Hg2+的甲基化创造有利条件。
