What is it about?

We showed in this article that nanocellulose is a bio-compatible material, which can be efficiently applied for fabrication of artificial biofilms with entrapped cyanobacterial and algal cells. These biofilms can be further utilized for production of hydrogen and other biofuels.

Why is it important?

Immobilization matrices for the photosynthetic microbial production of hydrogen were fabricated using TEMPO-oxidised cellulose nanofibrils with different strategies employed to enhance the matrix water stability. We showed that these versatile templates display high compatibility with oxygenic phototrophic organisms, and that they are suitable for thin-layer cell entrapments both in hydrogel and dry solid film states. They possess several advantageous features, which make them more attractive than other natural matrix materials.

Perspectives

These findings open new possibilities for developing a novel technology platform with tailored pore-size and controllable surface charge that targets sustainable chemical production by oxygenic photosynthetic microorganisms.
