Silica nanoparticle growth during the polymerization of silicic acid in saline geothermal brine from the Yamagawa geothermal power station, Japan, was examined using dynamic light scattering (DLS). Two types of polysilicic acid particles (large and s

In experiments, flow rates through porous media were measured using raw brine (pH = 6.5, [SiO2] = 1130 mg/L) at Sumikawa Geothermal Power Plant in 2016. The flow rates decreased by up to 25% of the initial flow rate after 11 days. A geochemical clogg

A moderately thermophilic, aerobic, stalked bacterium (strain MA2T) was isolated from marine sediments in Kagoshima Bay, Japan. Phylogenetic analysis of 16S rRNA gene sequences indicated that strain MA2T was most closely related to the genera Rhodobi
