Given the growing interest in functional properties of nanocellulosic forms, bacterial cellulose nanocrystals (BCNCs) have gained attention as sustainable, high-performance materials for diverse applications. Although recent research has addressed use agro-industrial waste BCNCs production, limited been given to residual crude glycerol, a widespread byproduct biodiesel industry. Therefore, this work aimed synthesize and thoroughly characterize from nanocellulose (BNC) obtained through metabolism glycerol via novel strain Ancylobacter sp. STN1A. The influence sulfuric acid (H2SO4) hydrolysis time on BCNCs´ morphology physicochemical was evaluated. Severe conditions yielded shorter, narrower (0.91 μm × 40 nm; L/D = 22.8) with increased crystallinity (63%) high colloidal stability (-40.17 ± 0.68 mV), well slightly reduced thermal stability. In contrast, milder produced longer (1.13 42 26.9) similarly zeta potential (-44.13 0.73 while maintaining crystalline features starting BNC. These findings demonstrate tailor controlled support viability producing versatile byproducts, contributing both cost-effective production environmental sustainability.
