title: TEMPERATURE CHARACTERISTICS FOR SPEED OF MOVEMENT OF THIOBACTERIA.
abstract: The speed of translatory movement of Beggiatoa alba is governed by temperature in such a way that between 5 degrees and 33 degrees the temperature characteristics micro = 16,100 and micro = 8,400 respectively obtain for the temperature ranges 5 degrees to 16.5 degrees and 16.5 degrees to 33 degrees . The "break" at 16 degrees -17 degrees is emphasized by the occurrence of a wider latitude of variation in speed above this temperature. Above 16 degrees the progression of Thiothrix yields micro = 8,300. The possible relation of these values to that previously obtained for similar movement in (photosynthetic) Oscillatoria is commented upon.
