Abstract:
PURPOSE: A method for controlling movement of growing bacteria through vibration mode shape is provided to have desired arrangement of bacteria cellulose. CONSTITUTION: A method for controlling bacteria movement comprises: a step of inoculating bacteria in a culture device which can implement vibration mode; a step of leading vibration mode shape inside the culture device by applying a specific frequency; and a step of controlling bacteria movement to arrange bacteria along nodal point or nodal line generated by the vibration mode. A method for producing bacteria cellulose comprises: a step of inoculating Acetobacter xylinum in the culture device containing Ph-regulated culture medium; a step of leading vibration mode shape inside the culture device by applying a specific frequency; a step of culturing bacteria controlling bacteria movement; and a step of obtaining arranged bacteria cellulose.
Abstract:
PURPOSE: A method for controlling bacteria movement is provided to produce bacteria cellulose membrane with fiber structure of even arrangement and uniform thickness. CONSTITUTION: A method for controlling bacteria movement comprises: a step of treating bacteria to attach a reaction unit of charged particle or magnetic particle on the bacteria surface; a step of inoculating the treated bacteria to culture device; and a step of controlling the movement of inoculated bacteria by operating reaction source according to controlling purpose. The used bacteria strain is Acetobacter xylinum.
