Abstract
A positive pressure effect (1.4 to 3.3x) on the binding of Mn by a natural population of bacteria in a deep-sea hydrothermal plume was discovered over the intermediate pressure range of 1 to 200 atm (1 to 200 bars; ca. 1.01 x 10 to 2.03 x 10 kPa). The data suggest Mn binding is functionally barophilic rather than simply barotolerant.
摘要
在深海热液羽流中自然菌群的作用下，在 1 至 200 大气压（1 至 200 巴；约 1.01 x 10 至 2.03 x 10 kPa）的中间压力范围内，发现对 Mn 结合具有正压效应（1.4 至 3.3x）。这些数据表明，Mn 结合是功能上的嗜压性，而不仅仅是耐压性。
