“…The manganese coated algae samples from Mt. Asahidake had very similar morphology with algae found in Yunotaki Falls (Mita et al, 1994;Usui and Mita, 1995) and Komanoyu hot spring (Miura and Hariya, 1997), where microbial activity was shown to produce manganese oxide minerals.…”

Abstract:Mt. Asahidake is an active volcano, with more than 90 active wells, in the Daisetsu volcanic group located in central Hokkaido, Japan. Wells along the Yukomanbetsu-sawa River showed high manganese concentrations and associated manganese deposits. These deposits consist of manganese oxides, and the concentration of iron is very low except for one sample collected from the upper reach of the river. Most of the wet samples showed basal diffraction characteristic of todorokite (9.6 Å). Cultivation tests showed that microorganisms were responsible for the oxidation of dissolved Mn 2+ in the Asahidake hot spring. The dissolved Mn 2+ concentration in the sterilized hot spring water was unchanged after four days, whereas the Mn 2+ concentration in the sterilized hot spring water with a small amount of fresh manganese wad was decreased to zero after three days, and manganese oxide formed. This result implies that the activity of microorganism oxidizes dissolved Mn 2+ and forms manganese oxide at the Asahidake manganese deposits. In addition to Komanoyu hot spring and Yunotaki Falls, this is the third report of microbial activity forming considerable deposits of manganese oxides in hot spring waters.

“…These deposits are important for understanding the process of deposition of older manganese deposits because the precipitation process can be observed directly. Recent studies have shown that most of these deposits are formed as a result of microbial activity (Hariya and Kikuchi, 1964;Mita et al, 1994;Usui and Mita, 1995;Mita and Miura, 2003). However, data on the depositional processes and deposition rates of these manganese oxides are very limited.…”

“…The depositional rate of manganese oxide has been estimated to be about 1100 kg/year (Hariya et al, 1992). The Yunotaki deposit is an example of manganese biomineralization (Mita et al, 1994) and is the largest recent manganese deposit in the world where biologically activated precipitation is taking place.…”

An outcrop of manganese oxide about one meter thick, inter − bedded with several volcanic ash layers, is found at the Yunotaki hotspring, Hokkaido, Japan. The manganese wad is precipitated from hydrothermal water. On the basis of the previously known age of the inter − bedded volcanic ash layers, linked to well − known eruptions, it has been possible to determine the chronology of the manganese oxide precipitation. The ash layers were identified by the chemical composition of the separated volcanic glasses. Since the lowermost manganese oxide layer of this outcrop occurs immediately above the mud flow of Mt. Ponmachineshiri (one volcano of Mt. Meakan) without the presence of any intermediate soil layer between them, it's age of formation could be near the age of the mud flow, i.e. 4500 − 5000 years BP. The manganese oxide layers in the top 50 cm of the outcrop are comparatively softer than those occurring below 50 cm and commonly have the texture of the aggregate of a filament structure. Manganese oxide occurring below 50 cm is hard and has a diagenetically altered texture reflecting change in the filament structure to a grain aggregate structure. These oxides have lost their structural water and the mineralogy has begun to change from todorokite (10Å phase) to birnessite (7Å phase) during the diagenetic process.

“…Accordingly, the treatment of Mn-rich water costs high. It has been reported that Mnoxidizing bacteria play an important role in the precipitation of manganese oxide minerals at neutral pH environments, such as hydrothermal vents [1][2][3][4] and in manganese mine environments. 5) Application of the bacteria to water treatment is interesting and attractive.…”

Removal of Manganese(II) Ions from Water by <I>Leptothrix discophora</I> with Carbon Fiber

To apply manganese-oxidizing bacteria to waste water treatment, basic performance of the manganese-oxidizing bacterium, Leptothrix discophora, distributed by ATCC was examined. In addition, the effect of carbon fiber on the oxidation by the bacterium was also investigated, since carbon fiber was reported to accelerate the growth of activated sludge during sewage treatment. The bacterium was found to be active in the medium containing 24 ppm Mn(II) ions, the concentration being about 8 times higher than the recommended one and practically useful level. The oxidation rate was higher with the static culture than the shaking culture. This was considered to be due to physical damage to the sheath structure of bacteria which is reported to be important to oxidize Mn(II) ions. The carbon fiber did not accelerate the microbial oxidation of Mn(II) ions. This is partly attributed to the lack of contact between the bacterial cell, which floated as thin membranes, and the carbon fiber sunk in the bottom of vessels. However, oxidized Mn species precipitated on the carbon fiber, which resulted in an improvement of the transparency of water. This effect is different from the one caused by activated carbons, since the carbon fiber has very low specific surface area and no pore structure. The effect was more remarkable in the shaking culture than the static culture, indicating that organic substances originated from the bacterium play an important role in the adsorption of oxidized Mn species.
