Abstract
Microorganisms' mass cultivation in open-environment is demanded to accelerate the use of microorganisms itself and its metabolite to reduce the dependence on fossil resources. In tissue engineering, cell-laden microfibers which grow biological cell within the fiber has a high profile. One approach is to structure fiber with calcium alginate. In order to apply this technique in microorganisms' cultivation, we proposed a process to fabricate hollow microfiber in this study. We also experimentally verified that porous surfaced hollow microfiber worked as protection for inside microorganisms from viruses. Our results show that hollow microfiber has a potential to culture microorganisms massively in open-environment.
