Abstract

Objective: To evaluate the nano-cellulose production for Gluconacetobacter xylinus in presence of molasses of cane under static conditions and / or of intermittent air flow. Methods: Anova factorial was realized where they involved as incidental variables in the process the condition of aeration (static Culture without aeration and static culture with aeration), and as variable of response in the cellulose production (represented like wet weight, dry weight, compressibility and thickness). Aso applied an analysis of comparison of averages and one proves t-test, with the software Staph graphics centurion version XVII.I. Findings: Across this study, it was possible to verify that the bacterium G. xylinus in static conditions with superficial aeration and using molasses as source of carbon, a concentration of 103 g L−1 was obtained of Bacterial Cellulose, approximately 20%, more than in the static culture without aeration. Likewise, the commercial value of the way of culture used (Max Mza) was minor than that of other previous studies where used reagents of analytical degree (costlier) while we used molasses and reagents of industrial degree (cheaper). Applications: This work contributes for further study on the effect of the molasses and other Sources of carbon on the cellulose production in such a way that the production increases and that the costs diminish in order to climb the process. Likewise, the application of aeration as superficial way allows the synthesis by culture more efficient, and therefore the production of the biopolymer increases.
