Abstract:
In the present preliminary study, we report results for the biocellulose nanofibres production by Gluconacetobacter xylinus. Production was examined by utilizing different feedstocks of single sugars and sugar mixtures with compositions similar to the acid hydrolyzates of different agriculture residues. Profiles for cell proliferation, sugar consumption, and the subsequent pH changes were thoroughly analyzed. Highest biocellulose production of 5.65 g/L was achieved in fructose medium with total sugar consumption of 95.57%. Moreover, the highest production using sugar mixtures was 5.2 g/L, which was achieved in feedstock with composition identical to the acid hydrolyzate of wheat straws. This represented the highest biocellulose yield of 17.72 g/g sugars compared to 14.77 g/ g fructose. The lowest production of 1.1 g/L and 1.75 g/L were obtained in xylose and glucose media respectively, while sucrose and arabinose media achieved relatively higher production of 4.7 g/L and 4.1 g/L respectively. Results reported in this study demonstrate that agriculture residues might be used as potential feedstocks for the biocellulose nanofibres production.
