4. Conclusions
Herein, we demonstrated that electrospun PHB nanofibers can be used as an efficient immobilization support for enzymatic processes. In addition to the high surface area-to-volume ratio, strong and specific interactions with phasins enabled selective immobilization of phasin-fused enzymes in a uniform orientation. The combined use of PHB nanofibers and phasin fusion tags cold contribute to the development of efficient enzymatic processes for the production of chemical materials. The bio-compatibility of PHB also makes it suitable for immobilization in biomedical applications.
