Three different branching patterns for less frequent (I), standard (II) and frequent (III) branching affect the HGU (**A**) and the area of the antibiotic producing cells (**B**) at the end of log phase. Regression lines utilized to determine the HGU and the time of maximum succesful branching (**C** and **D** 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%).
