Model predictions using different branching patterns.

<p>Three different branching patterns for less frequent (I), standard (II) and frequent (III) branching affect the HGU (<b>A</b>) and the area of the antibiotic producing cells (<b>B</b>) at the end of log phase. Regression lines utilized to determine the HGU and the time of maximum succesful branching (<b>C</b> and <b>D</b> respectively) based on average tip velocities of 2.5 μm/h (−60%), 4.4 μm/h (−30%), 6.3 μm/h (±0), 8.2 μm/h (+30%), 10 μm/h (+60%) and 12.6 μm/h (+100%).</p>
