Patent number: 9340765Abstract: A method to suppress biofilm formation in a growth chamber of a chemostat is described. The method includes the steps of adding a lysis agent to an isolated portion of the growth chamber, and reuniting the isolated portion with the rest of the growth chamber. The microfluidic chemostat includes a growth chamber having a plurality of compartments. Each of the compartments may be fluidly isolated from the rest of the growth chamber by one or more actuatable valves. The chemostat also included a nutrient supply-line to supply growth medium to the growth chamber, and an output port to remove fluids from the growth chamber.Type: GrantFiled: March 26, 2013Date of Patent: May 17, 2016Assignee: California Institute of TechnologyInventors: Frederick Balagadde, Carl L. Hansen, Emil Kartalov, Stephen R. Quake
