Spruce mannan was extracted and characterized by FT-IR, SEM and specific surface area test. FT-IR showed it was branched galactoglucomannan; SEM revealed its layered surface and rod-like polymerization units with spherical tops at high magnification; it had small specific surface area and large pore size. Hydrolysis experiments showed spruce mannan inhibited commercial second-generation cellulase (max inhibition rate 22.22%), with inhibition related to hydrolysis time, enzyme dosage and mannan amount. Tween 80 alleviated this inhibition (min inhibition rate 8.69%), promoted \u03b2-glucosidase at high concentration (max promotion rate 28.57%), and greatly reduced mannan\u2019s hydrolysis effect (inhibition rate down to 31.82%). This study provides a basis for improving mannan utilization and biomass energy conversion.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5518],"tags":[5624,5626,5625,5627,328],"release_year":[5476],"ppma_author":[5621,5622,5623],"class_list":["post-6034","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-71-number-2-2026","tag-cellulase","tag-enzyme-hydrolysis","tag-mannan","tag-mechanism","tag-spruce","release_year-5476"],"featured_image_src":null,"author_info":{"display_name":"Ivanke","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/ivanke\/"},"authors":[{"term_id":5621,"user_id":0,"is_guest":1,"slug":"yunjing-lu","display_name":"YUNJING LU","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5622,"user_id":0,"is_guest":1,"slug":"shilin-xu","display_name":"SHILIN XU","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":5623,"user_id":0,"is_guest":1,"slug":"ziwei-li","display_name":"ZIWEI LI","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/6034","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=6034"}],"version-history":[{"count":2,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/6034\/revisions"}],"predecessor-version":[{"id":6037,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/6034\/revisions\/6037"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=6034"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=6034"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=6034"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=6034"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=6034"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
