A moderately thermophilic culture was enriched and adapted to bioleach chalcopyrite at high pulp density. In order to further improve copper extraction, effects of galvanic interaction on bioleaching performance and community dynamics were investigated by adding pyrite. Copper extractions were improved by 2.91 and 1.97 times in the initial and the final stages when pyrite was present, respectively. However, it did not benefit chalcopyrite dissolution in the middle stage. Community dynamics analysis showed that succession of the attached cells was significantly different from community dynamics of the planktonic cells. One of planktonic populations always dominated the communities in most cases, while no species had absolutely competitive advantages in the attached communities. In addition, the presence of pyrite had significant effects on planktonic and attached community structures, and could accelerate planktonic community succession.

适度嗜热的培养物在高纸浆密度下富集并适于生物浸出黄铜矿。为了进一步改善铜的提取，通过添加黄铁矿研究了电相互作用对生物浸出性能和群落动力学的影响。当存在黄铁矿时，铜的提取在初始阶段和最终阶段分别提高了2.91和1.97倍。但是，在中间阶段，它不能使黄铜矿溶解。群落动力学分析表明，贴壁细胞的演替与浮游细胞的群落动力学显着不同。在大多数情况下，浮游种群之一一直占据着社区的主导地位，而在附属社区中没有任何物种具有绝对的竞争优势。此外，
