13. Thermocrinis ruber gen. nov., sp. nov., a Pink-Filament-Forming Hyperthermophilic Bacterium Isolated from Yellowstone National Park
A novel hyperthermophilic bacterium was isolated from pink filamentous streamers (pink filaments) occurring in the upper outflow channel (temperature, 82 to 88°C) of Octopus Spring in Yellowstone National Park, Wyo. The gram-negative cells grew at low salinity at temperatures up to 89°C in the neutral to alkaline pH range. Depending on the culture conditio

14. Bacteriolytic Action of Fluoride Ions
Bacillus subtilis, Neisseria subflava, and LYT coccus were found to undergo massive lysis after growth in media containing 0.01 to 10 mM NaF. When cells of these organisms were transferred from late-exponential-phase cultures to 0.02 M sodium phosphate buffer plus 0.1 M KCl, they underwent spontaneous autolysis. Cells grown in media with fluoride were more l

17. Treatment of Lactic Acidosis with Dichloroacetate in Dogs
Lactic acidosis is a clinical condition due to accumulation of H+ ions from lactic acid, characterized by blood lactate levels >5 mM and arterial pH <7.25. In addition to supportive care, treatment usually consists of intravenous NaHCO3, with a resultant mortality >60%. Dichloroacetate (DCA) is a compound that lowers blood lactate levels under various condit
