Abstract

A bacterial isolate, strain FMn 1, from reservoir sediment oxidized MN2+ when tested in growing culture and resting-cell suspension. The oxidation was biologically mediated and not the result of autoxidation because at a MnSO4 . H2O concentration of 0.05%, the pH remained below 7.5 for the duration of the experiments. The production of manganese oxide was qualitatively and quantitatively demonstrated. The manganese-oxidizing activity of this organism was found to be inducible.

淡水细菌分离株fmn1生长细胞和静息细胞氧化锰的比较。
从水库沉积物中分离的菌株FMn 1在生长培养和静止细胞悬浮液中氧化了MN2+。氧化是生物介导的,而不是自氧化的结果,因为在MnSO4中。0.05%的水,pH在实验过程中保持在7.5以下。对氧化锰的生产进行了定性和定量论证。该生物的锰氧化活性是可诱导的。
