<P><B>Abstract</B></P> <P>Pecan nutshell is an abundant waste with a high content of carbohydrates. According to its chemical composition, pecan nutshell could be used as carbon source for <I>Gluconacetobacter entanii</I>, a bacterium that produces cellulose with high purity and nanometric characteristics. Bacterial cellulose (BC) was obtained from a static culture medium using pecan nutshell as carbon source and saccharose as control. Results showed that the pecan nutshell could be used as carbon source for production of BC. The cellulose yield ranged around 2.816 ± 0.040 g/L for 28 days. The morphological, structural and chemical properties of the cellulose produced were similar to those reported for others BC. The spectroscopic characterization indicated the chemical functionalization of BC and the reduction of its crystallinity. The production of BC with <I>G. entanii</I> using pecan nutshell as carbon source, is the first report. The BC could have potential use in chemical functionalization and in the preparation of biocomposites.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Pecan nutshell could be used as carbon source for production of BC by <I>G. entanii</I>. </LI> <LI> Cellulose produced by <I>G. entanii</I> had high purity. </LI> <LI> BC production by <I>G. entanii</I> using pecan nutshell is the first report. </LI> <LI> Data obtained can be useful for the synthesis of methylcellulose from other BC. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
