Although the production of carboxymethylcellulose from different raw materials is commercial, its preparation from agro-industrial residues has still been poorly explored in terms of performance, cost-effectiveness, and sustainability. Here, sugarcane bagasse was used as raw material for the carboxymethylcellulose (CMCb) syn thesis within the biorefinery context. Sequential treatments were used for the removal of hemicellulose and lignin and the isolation of cellulose, whose conversion into CMCb was carried out through treatments with NaOH and monochloroacetic acid (MCA). The chemical modifications led to a CMCb with a substitution degree of 0.44, purity of 71.3 %, and 32 % crystallinity. Our residue-based CMCb was adequate for microorganism encapsula tion, a high-value application, promoting viable conidia after 5 months of storage in equivalent conditions of high-purity, commercial CMC. Our findings show a route for the preparation of valuable polysaccharides from waste in future biorefineries, which, depending on their characteristics, can be applied in different processes. Here we use them for the encapsulation of a bioagent, although they can easily be used in other applications such as packaging and coating |
