Figure 3From: A defined medium to investigate sliding motility in a Bacillus subtilis flagella-less mutantThe K+-dependence of hag growth on the defined medium requires the high affinity potassium transporter (KtrAB), but not the low affinity transporter (KtrCD). MSggN plates were prepared with the indicated levels of KCl, inoculated in triplicate with either the hag strain, or hag ktrAB or hag ktrCD triple mutants (Table 1), and photographed after 24 h growth at 37°C.Back to article page
