Cellulose, polysaccharide yopangidwa ndi ma monomers a glucose olumikizidwa ndi ma β-1,4-glycosidic bonds, ndiye polima wachilengedwe wochuluka kwambiri padziko lonse lapansi. Wopezeka kwambiri m'makoma a maselo a zomera, umapangitsa kuti kapangidwe kake kakhale kolimba, zomwe zimathandiza mitengo kufika kutalika kwakukulu ndi masamba kuti isunge mawonekedwe awo. Thonje, gwero lenileni lachilengedwe la cellulose, lili ndi 90% ya polima iyi, pomwe matabwa nthawi zambiri amakhala ndi 40-50% cellulose, limodzi ndi lignin ndi hemicellulose. Algae ndi mabakiteriya ena amapanganso cellulose, zomwe zimapangitsa kuti ifalikire mwachilengedwe.

Kutulutsa cellulose kumaphatikizapo kuipatula ku zigawo zina za zomera. Mu makampani opanga zamkati ndi mapepala, matabwa amapangidwa ndi mankhwala (pogwiritsa ntchito sulfates kapena sulfites) kapena makina opukutira kuti achotse lignin ndikupatula ulusi wa cellulose. Pa ntchito zoyera kwambiri, monga mankhwala ndi zakudya, njira zina zoyeretsera monga bleaching ndi enzyme treatment zimagwiritsidwa ntchito. Nanocellulose, yochokera ku cellulose kudzera mu acid hydrolysis kapena mechanical fibrillation, yakhala chinthu chamtengo wapatali chifukwa cha mawonekedwe ake apadera pa nanoscale.

Kusinthasintha kwa selulosi kumapangitsa kuti igwiritsidwe ntchito kwambiri m'mafakitale osiyanasiyana.kupanga mapepala, ulusi wa cellulose ndiye chinthu chachikulu chopangira zinthu zopangira mapepala, zomwe zimapangitsa kuti zinthuzo zikhale zolimba komanso zosinthasintha.makampani opanga nsalu, thonje la cellulose limapota ulusi ndi kuluka nsalu, zomwe zimayamikiridwa chifukwa cha kupuma bwino komanso kumasuka kwawo.zakudya zogwiritsidwa ntchitoCellulose imagwira ntchito ngati ulusi wothandiza pa zakudya, kulimbitsa thanzi la kugaya chakudya, ndipo imagwira ntchito ngati chokhuthala, chokhazikika, kapena chosakaniza muzinthu monga ayisikilimu ndi zodzoladzola za saladi.
