Formation of Biofilm Streamers (1 of 2) (video) Princeton University Loading video... Caption This video shows how, over a period of about 40 hours, bacterial cells (green) flowing through the tube form a green biofilm on the walls. Over the next ten hours, researchers sent red bacterial cells through the channel. The red cells became stuck in the sticky biofilm and began to form thin red streamers. Once stuck, these streamers in turn trapped additional cells, leading to rapid clogging.
