Abstract Several dissimilatory metal-reducing bacteria and a halophilic bacterium are able to induce manganese carbonate (rhodochrosite) precipitation. In this study, it was revealed that Ensifer adhaerens JCM 21105T, Microbacterium testaceum JCM 1353T, Pseudomonas protegens DSM 19095T, and Rheinheimera texasensis DSM 17496T, which are calcite-forming bacteria, were able to aerobically induce the precipitation of manganese carbonate crystals on an agar medium. In the case of all four strains, the principal morphology of the precipitated manganese carbonate crystals was that of micro-sized spheres, when they were aerobically cultivated over the entire surface of the agar medium at 28 °C for 7 days.

方解石形成菌诱导碳酸锰沉淀

摘要 几种异化金属还原菌和嗜盐菌能够诱导碳酸锰（菱锰矿）沉淀。在这项研究中，发现 Ensifer adhaerens JCM 21105T、睾丸微杆菌 JCM 1353T、Pseudomonas protegens DSM 19095T 和 Rheinheimera texasensis DSM 17496T，它们是方解石形成细菌，能够在有氧条件下诱导碳酸钙晶体沉淀中等的。在所有四种菌株的情况下，当它们在琼脂培养基的整个表面在 28°C 下有氧培养 7 天时，沉淀的碳酸锰晶体的主要形态是微型球体。
