Formatted abstract
The cell length distributions of an E. coli suspension homogenized at 21 MPa and 41 MPa are compared with the length distribution of the feed sample. A chi-squared test shows the distributions are significantly different, with the homogenate samples having a lower than expected number of long cells and an abundance of small cells. A chi-squared comparison of the two homogenate samples shows no significant difference in the distributions, despite a large difference in the total average disruption. The results suggest that septated cells are preferentially disrupted during homogenization. Improved homogenizer performance may therefore be obtained if economic methods of increasing the septated fraction near the completion of a fermentation can be developed.
