F colonies developing from inocula of varying geometrical layout. a. Colonies from ring inocula blotted using plastic matrices of varying diameter. b. Colony planting (1 μl, ca 105 cells) on the colony background of bacteria (0, 1, or 2 days old). Insets: controls. c. Simple cases of elongated plantings. d. Ring-colony encounters. Mutual influencing of a colony and a ring planted in different time intervals. All colonies are shown at day 7; bar = 1 cm.
