摘要

我们分离了23株耐氧化有机硒代谢物甲基亚硒酸（MSeA）的土壤细菌菌株。其中，Pseudomonas sp. M10表现出最高的MSeA耐受性，并将MSeA转化为挥发性二甲基二烯醚，符合氧化还原驱动的非酶促过程。这是细菌介导的MSeA挥发的第一篇报道，揭示了以前未被认识到的微生物对陆地和大气隔间之间硒通量的贡献。

Production of dimethyldiselenide from methaneseleninic acid by soil bacteria.

We isolated 23 soil bacterial strains tolerating methaneseleninic acid (MSeA), an oxidized organoselenium metabolite. Among them, Pseudomonas sp. M10 exhibited the highest MSeA tolerance and converted MSeA into volatile dimethyldiselenide, consistent with a redox-driven, non-enzymatic process. This is the first report of bacterially mediated MSeA volatilization, revealing a previously unrecognized microbial contribution to selenium flux between terrestrial and atmospheric compartments.
