“…Although cellulose is mainly used in the pulp and paper industry, it has been exploited, along with its derivatives (e.g., cellulose acetate (CA), carboxymethylcellulose (CMC), and ethylcellulose (EC)) and nanoforms (i.e., cellulose nanocrystals (CNCs), cellulose nanofibrils (CNFs) and bacterial nanocellulose (BNC) [ 36 , 48 , 49 ]), for other purposes, including textiles [ 50 ], fuel cells [ 51 , 52 , 53 ], electronics [ 54 , 55 ], water remediation [ 56 , 57 , 58 ], food packaging [ 59 , 60 , 61 ], cosmetics [ 62 , 63 ], drug delivery [ 64 , 65 ], cell and tissue cultures [ 66 , 67 ], just to mention some examples. In order to be applied in these multiple domains, cellulose needs to be extracted from biomass resources by conventional technologies (e.g., kraft pulping) or innovative methodologies (e.g., extraction with ionic liquids (ILs) or deep eutectic solvents (DES)) [ 68 , 69 , 70 , 71 ] or produced in its pure form by non-pathogenic bacteria (e.g., Komagataeibacter ) [ 63 , 72 , 73 ].…”
