The bacteria can move by the means of swimming, pushing, twitching and gliding. They can also move randomly. They do not need any specific structures for their movements. Taxis, pilli, flagella and actin helps in their movement. The bacterial cell have the ability to move via taxis and can also use their pilli in order to move together. That is the reason the ETPUM on the Lycra-sealed slide is redistributed. The bacterial cells using taxis can gain energy from the polyurethane.
