摘要

根瘤菌层的易变碳和养分可促进痕量气体氧化细菌（TGOB）的活性，但根瘤菌层效应在激活后支持其持续活性的能力却较少受到关注。在此，我们假设种植前土壤中 TGOB 的活化反应与小麦生长后其活性的持续性成正比。在含有高浓度氢气（H2）、一氧化碳（CO）或甲烷（CH4）的静态环境下，TGOB 在沙壤土和泥炭土中被活化。事实证明，我们的假设在沙壤土中成立，而泥炭土中较高的有机物则不利于 TGOB 活性的持续。我们得出的结论是，痕量气体氧化反应的能量潜力和土壤养分都与 TGOB 活性的持续性有关。

A rhizosphere effect promotes the persistence of gas oxidization activity in soil

Labile carbon and nutrients of the rhizosphere promote the activity of trace gas oxidizing bacteria (TGOB), but the capacity of the rhizosphere effect to support their persistence upon activation has received less attention. Here, we hypothesized that the activation response of TGOB in soil before planting is proportional to the persistence of their activity after wheat growth. The TGOB were activated in sandy-loam and peat soils under a static atmosphere containing elevated concentration of hydrogen (H₂), carbon monoxide (CO) or methane (CH₄). Our hypothesis was proven to hold true in sandy-loam soil, whereas higher organic matter in peat soil was less favourable for the persistence of TGOB activity. We conclude that the energy potential of the trace gas oxidation reaction and soil nutrients both intervein in the persistence of TGOB activity.
