概要:

Red brownish microbial mats grow on the surface of drainage pond at Iriki Kaolin deposit, Kagoshima Prefecture, Japan, are predominantly iron oxidizing bacteria. The Fe-bacteria quickly occur on the surface of acidic water pH 3.4 within few days. The biofilms are composed of amorphous iron hydroxides and ferrihydrite are found both in natural system and cultured solution after 90 days under pH 6→2.5 condition. Optical and SEM-EDX microscopy showed the formation … processes of Fe-rich biofilms with green unicellular bacteria occurred in the system of deionized water and kaolinite blocks. In the system, Fe and S-rich biofilms around kaolinite blocks can be seen, suggesting kaolin minerals encourage to form the biofilms as accelerator in the acidic drainage pond. The biofilms use ferrous ions as their energy source through the oxidation into ferric ions. 続きを見る
