Increases hydrostatic pressure varied the 72-h growth yield of three bacterial isolates from the deep sea in the presence of heavy metal cations of Mn, Cu, Co, and Ni, depending on the bacterial isolate, the metal cation and its concentration, and the level of hydrostatic pressure. Above atmospheric, hydrostatic pressure was found to have one of the following four effects on the response of culture growth to a heavy metal cation. (i) It could be without effect; (ii) it could enhance inhibition by a metal cation; (iii) it could increase the 72-h growth yield by a metal cation; or (iv) it could protect against a growth inhibitory effect noted at a lower pressure. Possible reasons for these varied responses are discussed.
在存在锰、铜、钴和镍的重金属阳离子的情况下，增加静水压力会改变三种深海细菌分离株的72小时生长产量，这取决于细菌分离株、金属阳离子及其浓度以及静水压力水平。在高于大气压的情况下，发现静水压力对培养物生长对重金属阳离子的反应有以下四种影响之一。(i) 可能没有影响；(ii) 可能增强金属阳离子的抑制作用；(iii) 可能增加金属阳离子的72小时生长产量；或(iv) 可能防止在较低压力下观察到的生长抑制作用。讨论了这些不同反应的可能原因。
