<P><B>Abstract</B></P> <P>Potato peel waste (PPW) is employed as the first report on bacterial cellulose (BC) production by <I>Gluconacetobacter xylinus</I>. Scharification of PPW was performed by 2 M different mineral acids individually. The suitable pre-treatment conditions were determined by reducing sugar release. Although all acid PPW-hydrolysates culture media are studied to produce BCs. Nitric acid hydrolysate gives the high productivity value The influence of nitric acid PPW-hydrolysate culture condition parameters were applied throughout the Taguchi method and the optimum conditions for the highest BC yield (4.7 g/L) was observed after 6 days at 35 °C, pH 9, medium volume 55 ml and with 8% inoculum size. The instrumental analysis of PPW-BC, included FT-IR, Particle size distribution, BET, DSC, XRD and SEM are cleared that the PPW-BC recorded high crystalliny82.5%, excellent PDI. In general, this study revealed that nitric acid PPW-hydrolysate could be used as cost effective alternative medium for production of BC with sustainable processes that can overcome the environmental pollution.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Overcome the high BC production cost and decrease the waste of resources and environmental pollution. </LI> <LI> Demonstrated the PPW has great possibility produce BC and mild nitric acid is an effective pre-treatment tool in biomass pre-treatment technology. </LI> <LI> Produce nitric acid PPW-hydrolysate is encouraging for the cost-effective industrial production of BC. </LI> <LI> Produce BC from PPW media has excellent characters. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
