鉄バクテリアに関する研究(第1報) : Gallionella ferrugineaの発育過程における培地中の鉄および有機物の変動

抄録

Recent investigations had been made only on the biological studies of iron bacteria, one of organisms attributable to many evils caused by them with larger use of underground-water. This paper was described the studies on basal media for growth of iron bacteria, and variations of soluble irons (amounts of total iron and ferrous ion) in the media and organic matters in the precipitates. The bacteria (Gallionella ferruginea) was grown at 20±0.5° in the modified media of ones described by Lieske, Wolfe and Mudge, respectively, for which the varied concentration of nutrient salts, iron powder as its source and ventilation of CO₂ gas was employed. The bacteria was reproducibly cultivated and its growth was terminated after 7 to 10 days incubation in the modified media.
