Lodgers on manganese nodules: Sponges promote a high diversity

WebAbstract Mature spores of the marine Bacillus sp. strain SG-1 bind and oxidize manganese (II), thereby becoming encrusted with a manganese (IV) oxide. Both the function and mechanism of this oxidation are unknown, although evidence suggests that spore coat proteins are involved. WebMature dormant spores of marine Bacillus sp. strain SG1 catalyze the oxidation of Mn(II) to MnO2. We report that vegetative cells of the same strain reduced MnO2 under low-oxygen conditions. The rate of reduction was a function of cell concentration. hill and clark bourne
