The effects of sulphuric compounds on the ATP content of the peat moss Sphagnum fuscum

Luminometric determination of ATP in the photosynthetic tissues of the peat moss $\text{Sphagnum fuscum}$ proved to be a suitable technique in studying the effects of bisulphite and sulphate on the metabolism of the mosses. The method has the advantage that it is rapid and easy to perform, and that the results are reliable and equal with those obtained by using other techniques.Bisulphite (HSO₃^?) caused marked reductions in the ATP contents at the 1 mM level, and the 5 mM level was clearly detrimental to the energy metabolism of the mosses. In contrast, sulphate (SO₄^2?) increased the ATP contents markedly.
