We describe the combined application of microsensors and molecular techniques to investigate the development of sulfate reduction and of sulfate-reducing bacterial populations in an aerobic bacterial biofilm. Microsensor measurements for oxygen showed that anaerobic zones developed in the biofilm within 1 week and that oxygen was depleted in the top 200 to 400 &mgr;m during all stages of biofil...
Microbially mediated insoluble technetium (Tc) formation was studied using surface water covering paddy fields. Surface water samples were collected from three kinds of flooded paddy soils: andosol, gley soil, and gray lowland soil. Insoluble Tc (> 0.2 μm in size) was formed in all surface water samples and the amounts ranged from 48.7 ± 2.2% of total Tc (gley soil) to 88.5 ± 3.1% (gray lowland...
