Magnesium perchlorate

They found that under these conditions , the magnesium perchlorate became bacteriocidal , meaning it killed all bacteria .

他们发现，在这些条件下，高氯酸镁变得具有杀菌作用，也就是它杀死了所有细菌。

In the laboratory , the researchers put magnesium perchlorate under short-wave UV radiation , similar to conditions on the surface of Mars .

在实验室中，研究人员们将高氯酸镁暴露于类似于火星表面环境的短波紫外辐射下。

The Bacillus subtilis lost viability within minutes in the presence of the magnesium perchlorate . The researchers also suggest that two other components on the Martian surface - iron oxides and hydrogen peroxide - may act alongside the perchlorates resulting in a 10 times increase in bacteria death .

这些暴露于高氯酸镁的枯草杆菌在几分钟内就失去了活性。研究人员们还表示，火星表面的其它两种成分--氧化铁和过氧化氢--可能会与高氯酸盐协作，导致细菌死亡率翻了10倍。
