Abstract:
Synthesized bacterial cellulose (BC) by Komagataeibacter nataicola TISTR 975 has shown
considerable potential in many applications, such as a novel wound healing system, an ultra-
strength paper, or even a facial mask that smells and nutrients are important. This work aims to
produce the cellulose facial mask via the crystalline fermentation of Komagataeibacter nataicola
TISTR 975 from hydrolyzed spent coffee grounds that are rich in coffee aroma and polyphenols.
The produced cellulose from hydrolysate showed higher mechanical strength when tested by
the Universal testing machine compared with the cellulose generated from the commercial broth.
Moreover, the water holding capacity was also enhanced. These results are positive for facial
masks since nutrients from the mask diffuse to the skin while moisture is persisted. Then this
bacterial cellulose facial mask made from spent coffee grounds is a prominent route to utilize
biomass efficiently.
