These problems are mitigated using mechanical refining at the cost of paper quality. Vessel enzymatic passivation, altering its adhesion to the fiber network and reducing its hydrophobicity is a way of improving paper quality. The object of this paper is to study how the enzymatic treatment by xylanase and by an enzymatic cocktail containing cellulases and laccases affect elemental chlorine free bleached\n                  <italic>Eucalyptus globulus<\/italic>\n                  vessel and fiber porosities, bulk, and surface chemical compositions. Thermoporosimetry revealed the vessel structure to be more porous, surface analysis showed its lower O\/C ratio and bulk chemistry analysis its higher hemicellulose content. Enzymes had different effects on porosity, bulk and surface composition of fibers and vessels, affecting vessel adhesion and hydrophobicity. It is proposed that differences in vessel and fiber porosity structures affect the enzymatic attacks, eventually causing vessel passivation.\n                <\/p>","DOI":"10.21203\/rs.3.rs-2159866\/v2","type":"posted-content","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T18:50:55Z","timestamp":1674672655000},"source":"Crossref","is-referenced-by-count":0,"title":["Eucalyptus globulus vessels enzymatic passivation: effect of pore structure on bulk and surface chemistry"],"prefix":"10.21203","author":[{"given":"\u00c1lvaro","family":"Vaz","sequence":"first","affiliation":[{"name":"Universidade da Beira Interior, R.
