DNA Builds and Strengthens the Extracellular Matrix in Myxococcus xanthus Biofilms by Interacting with Exopolysaccharides
Figure 5
DNA bound to M. xanthus EPS at different pHs.
The binding percentages of wild-type DK1622 chromosomal DNA (left) and commercial salmon sperm DNA (right) to isolated EPS were determined at different pHs, and the average ± SD is plotted. On the x-coordinate, ‘DNA’ represents different DNA samples, ‘EPS’ represents isolated M. xanthus EPS and ‘Cell*’ represents SW504 cells, which were added to the test system.
