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.
