Microbes Culture System Using Cellulose Tubes and Photocatalyst-Coated Glass Balls.

ABSTRACT

Currently, microbes are utilized in many fields, such as medicine, food and environment etc. For more application of microbes, we need a new culture system, which can culture target microbes in large quantities at low cost. Thereupon, we propose a culture system using cellulose tubes. Target microbes are encapsulated inside the cellulose tubes, where they acquire nutrients and oxygen through nano pores of the tubes and are protected from competitive microbes even in open environment. To further increase the amount of oxygen and nutritions available for the target microbes, we propose photocatalyst-coated glass balls (PCGB) to sterilize competing microbes outside the tubes. We experimentally verified the effectiveness of the proposed culture system by culturing Coryne gultamicum as the target microbes.
