Evaluation of sisal juice as potential carbon source for bacterial cellulose production

Abstract

Bacterial cellulose (BC) is a versatile biodegradable material of great technological potential. In this study, we evaluated the influence of initial sugar concentration, pH, different nitrogen sources, and cultivation time on the production of BC using sisal juice, an agroindustrial waste, as fermentative substrate. The higher production of BC was obtained after static cultivation of the bacteria for 10 days using the sisal juice with 15 g.L^-1 of sugars, pH 5, and 7.5 g.L^-1 of yeast extract. In comparison to the synthetic medium (HS), cellulose production yield in optimized sisal culture was 3 times higher, proving it as a suitable substrate for BC production.
