The researchers proposed that, if sulfate-reducing bacteria Numbers jumped as ice cover dropped, they should see increasing levels of inorganic sulfur over time.

研究人员认为，如果硫酸盐还原细菌的数量随冰盖减少而大量增加，他们也会看到无机硫水平也会随时间而不断增高。

Additionally the microorganisms must be supplied in the growth medium with nitrogen-containing compounds such as ammonium sulfate, ammonia, or urea, as well as with inorganic phosphates.

另外必须提供的微生物在与含氮如硫酸铵，氨水或尿素化合物生长介质，以及与无机磷酸盐。
