Selulose, polysaccharide igizwe na monomer za glucose zihujwe n'imigozi ya β-1,4-glycosidic, ni polymeri y'umwimerere iboneka cyane ku Isi. Iboneka cyane cyane mu nkuta z'uturemangingo tw'ibimera, itanga ubukana bw'imiterere, ituma ibiti bigera ku burebure bukomeye n'amababi kugira ngo bigumane ishusho yabyo. Ipamba, isoko karemano ya selulose, igizwe na 90% by'iyi polymeri, mu gihe ibiti bisanzwe bigizwe na 40-50% bya selulose, iherekejwe na lignin na hemicellulose. Algae na bagiteri zimwe na zimwe nazo zikora selulose, zikongera ikwirakwira ryayo karemano.

Gukuramo selulose bisaba kuyitandukanya n'ibindi bice by'ibimera. Mu nganda zikora ibimera n'impapuro, uduce tw'ibiti dushyirwa mu bimera bikoreshwa mu gusya ibinyabutabire (hakoreshejwe sulfate cyangwa sulfite) cyangwa gusya hakoreshejwe ikoranabuhanga kugira ngo bikureho lignin no gutandukanya imiyoboro ya selulose. Ku bijyanye no gukoresha imiti n'ibicuruzwa byo mu rwego rwo hejuru, nko gukoresha imiti n'ibiribwa, hakoreshwa izindi ntambwe zo gusukura nko gusibanganya no gutunganya enzyme. Nanocellulose, ikomoka kuri selulose binyuze muri hydrolysis ya aside cyangwa fibrillation ya mashini, yagaragaye nk'ibikoresho bifite agaciro gakomeye bitewe n'imiterere yayo yihariye kuri nanoscale.

Uburyo bwo gukora ibintu bitandukanye bwa selulosi butuma ikoreshwa cyane mu nganda zitandukanye.gukora impapuro, insinga za selulose ni zo zikoreshwa cyane mu bikoresho fatizo, zitanga imbaraga n'ubushobozi bwo koroshya ibikoresho by'impapuro. Muriinganda z'imyenda, cellulose y'ipamba irazungurutswa ikavamo ubudodo hanyuma ikavamo imyenda, ihabwa agaciro kubera ko ihumeka neza kandi ikoroha.ikoreshwa ry'ibiryoSelulose ikora nk'umunyu ngugu mu mirire, igateza imbere ubuzima bw'igogora, kandi ikora nk'iyongera imbaraga, itera imbaraga, cyangwa igabanya ubukana mu bicuruzwa nka ice cream na salade.
