FIG. 3.
Turn angle distribution for S. acidocaldarius at 60°C and pH 3 (●). The mean turn angle was 54 ± 29°. The total number of cells tracked in this data set was 55, with a total of 1,010 turns. The turn angle distribution was not a function of temperature or pH. The unimodal distribution for E. coli (11) (——) and the bimodal distribution for P. putida (8) (- - - -) are shown for comparison.
