Over the past several years, research from University of California San Diego biologist Gürol Süel's laboratory has uncovered a series of remarkable features exhibited by clusters of bacteria that live together in communities known as biofilms.
Biofilms are prevalent in the living world, inhabiting sewer pipes, kitchen counters and even the surface of our teeth. A previous research study demonstrated that these biofilms employ sophisticated systems to communicate with one another, while another proved biofilms have a robust capacity for memory.
Süel's laboratory, along with researchers at Stanford University and the Universitat Pompeu Fabra in Spain, has now found a feature of biofilms that reveal these communities as far more advanced than previously believed. Biological Sciences graduate student Kwang-Tao Chou, former Biological Sciences graduate student Daisy Lee, Süel and their colleagues discovered that biofilm cells are organized in elaborate patterns, a feature that previously only had been associated with higher-level organisms such as plants and animals. The findings, which describe the culmination of eight years of research, are published Jan. 6 in the journal Cell.
