In this study, an acclimated manganese-oxidizing bacteria (MnOB) consortium, QBS-1, was enriched in an acid mine area; then, it was used to eliminate Mn(Ⅱ) in different types of wastewater. QBS-1 presented excellent Mn removal performance between pH 4.0 and 8.0, and the best Mn-removal efficiency was up to 99.86% after response surface methodology optimization. Unlike other MnOB consortia, the core bacteria of QBS-1 were and , which might play vital roles in Mn removal. Besides that, adsorption, co-precipitation and electrostatic binding by biological manganese oxides could further promote Mn elimination. Finally, the performance of the Mn biofilter demonstrated that QBS-1 was an excellent inoculant, which indicates good potential for removing Mn contamination steadily and efficiently.

在本研究中，一种驯化的锰氧化细菌（MnOB）菌群QBS-1在酸性矿区富集；然后，将其用于去除不同类型废水中的Mn（Ⅱ）。QBS-1在pH 4.0至8.0之间表现出优异的锰去除性能，经过响应面法优化后，最佳锰去除效率高达99.86%。与其他MnOB菌群不同，QBS-1的核心细菌是[此处原文缺失细菌名称]和[此处原文缺失细菌名称]，它们可能在锰去除中发挥重要作用。除此之外，生物锰氧化物的吸附、共沉淀和静电结合可进一步促进锰的去除。最后，锰生物滤池的性能表明QBS-1是一种优良的接种剂，这表明其在稳定高效去除锰污染方面具有良好的潜力。
