Novel research on nanocellulose production by a marine Bacillus velezensis strain SMR: a comparative study.

ABSTRACT: Bacterial nanocellulose (BNC) is a nanofibrillar polymer that possesses unique characteristics such as high chemical purity, mechanical strength, flexibility, and absorbency. In addition, different bacterial strains can form nanocellulose (NC) in multiple shapes and sizes. This study describes the first report of a marine Bacillus strain that is able to synthesize NC. The strain identified as B. velezensis SMR based on 16S rDNA sequencing, produced highly structured NC, as confirmed by X-ray diffraction (XRD) and Scanning Electron Microscopic Analysis (SEM). In Hestrin-Schramm (HS) medium, B. velezensis SMR produced twice the quantity of BNC in comparison to the reference strain, G. xylinus ATCC 10245. The ability of B. velezensis SMR to produce NC using different industrial waste material
