Sphaerotilus

Other iron oxidizers include Sphaerotilus, Crenothrix, and Lep-tothrix species. Each bacterium is filamentous. 

Microscopic observations of the sludge flock showed the presence of filamentous organisms, Sphaerotilus natans, in high concentrations. The presence of these organisms was expected to be due to deficiency of the nitrogen in the wastewater.

Manganese is cycled by microorganisms in similar ways to iron. Mineralization of manganese oxides (e.g., bimessite) is often attributed to a variety of bacteria, including Gallionella, Leptothrix, Sphaerotilus, Pseudomonas, and Pedomicrobium spp. Enzymes involved in Mn oxidation have been studied in some detail (e.g., Brouwers et al. 2000).

Some examples of lOB are Gallionella, Sphaerotilus, Siderocapsa, and Crenothrix Recently, two new lOB isolates, namely, Gordonia sp. MZ-89 and Enterobacter sp. MOllOl, have been shown to have measurable effects on carbon steel corrosion. Figure 4.24 shows some of the findings on these new lOB isolates.
