This paper proposes a microbe culture technology in an open environment using hydrogel microtubes. Oil production microbes, such as Aurantiochytrium, have been discovered and are currently studied to produce fuels instead of fossil fuels. Scale-up of the culture systems of such microbes is critical for practical applications. The microbe culture in a nutrition-rich open environment, such as lakes and sewage plants, is preferable in terms of scales and cost, however, contamination of other native microbes is often fatal to the target microbes. Hydrogel microtubes that can be manufactured by microfluidic devices can encapsulate the microbes and allow oxygen and nutrition to diffuse through the tube walls while preventing other microbes from intruding inside. Therefore, the microbes can be cultured in any environments and scale-up is also possible. In this paper, we demonstrate that the contamination of microbes was prevented and target microbes were successfully cultured inside the microtube.
