      abstract     = {The surface distribution of flagella in peritrichous
                      bacterial cells has been traditionally assumed to be random.
                      Recently, the presence of a regular grid-like pattern of
                      basal bodies has been suggested. Experimentally, the
                      manipulation of the anchoring points of flagella in the cell
                      membrane is difficult, and thus, elucidation of the
                      consequences of a particular pattern on bacterial locomotion
                      is challenging. We analyze the bundle formation process and
                      swimming properties of Bacillus subtilis-like cells
                      considering random, helical, and ring-like arrangements of
                      flagella by means of mesoscale hydrodynamics simulations.
                      Helical and ring patterns preferentially yield
                      configurations with a single bundle, whereas configurations
                      with no clear bundles are most likely for random anchoring.
                      For any type of pattern, there is an almost equally low
                      probability to form V-shaped bundle configurations with at
                      least two bundles. Variation of the flagellum length yields
                      a clear preference for a single major bundle in helical and
                      ring patterns as soon as the flagellum length exceeds the
                      body length. The average swimming speed of cells with a
                      single or two bundles is rather similar, and approximately
                      $50\%$ larger than that of cells of other types of flagellar
                      organization. Considering the various anchoring patterns,
                      rings yield the smallest average swimming speed independent
                      of the type of bundle, followed by helical arrangements, and
                      largest speeds are observed for random anchoring. Hence, a
                      regular pattern provides no advantage in terms of swimming
                      speed compared to random anchoring of flagella, but yields
                      more likely single-bundle configurations.},
