Abstract excerpt
A novel facultative microaerophilic nitrate-reducing bacterium designated CA62N(T) was isolated from a thermal spring in France. Cells were non-motile rods (2-3 x 0.2 mum) and showed low cytoplasmic density when observed under a phase-contrast microscope. Strain CA62N(T) grew at temperatures between 50 and 75 degrees C (optimum 65 degrees C) and at a pH between 6.3 and 7.9 (optimum 7.0). NaCl was not required for...
