Firstly, the paper studied the optimum conditions that the laccase\/histidine system modified the OCC fiber, including enzyme dosage, histidine dosage, reaction time, reaction temperature, and pH. Experimental results showed that the optimum reaction conditions of laccase\/histidine system for OCC pulp were: dose of enzyme 1\u2009U\u00b7<jats:inline-formula id=\"j_npprj-2018-0079_ineq_001_w2aab3b7b4b1b6b1aab1c17b1b1Aa\">\n                     <jats:alternatives>\n                        <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/j_npprj-2018-0079_ineq_001.png\"\/>\n                        <m:math xmlns:m=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                           <m:msup>\n                              <m:mrow>\n                                 <m:mtext>g<\/m:mtext>\n                              <\/m:mrow>\n                              <m:mrow>\n                                 <m:mo>\u2212<\/m:mo>\n                                 <m:mn>1<\/m:mn>\n                              <\/m:mrow>\n                           <\/m:msup>\n                        <\/m:math>\n                        <jats:tex-math>{\\text{g}^{-1}}<\/jats:tex-math>\n                     <\/jats:alternatives>\n                  <\/jats:inline-formula>, 4\u2009h reaction time, pH 4.5, dose of histidine 1\u2009%. Under the optimum reaction conditions, the tensile and burst indexes of the sheet made from laccase\/histidine treatment were increased by 25.2\u2009% and 34.0\u2009%, compared with that of the control sample. The SEM results showed that compared with the control sample, the fibrillation of the fiber modified with laccase\/histidine was more obvious. Finally, the content of acid-insoluble lignin of the fiber was determined. The content of acid-insoluble lignin of the control sample was 29.2\u2009%, and the content of acid-insoluble lignin of the fiber treated by laccase\/histidine system in optimum reaction conditions was 16.0\u2009%, which decreased by 13.2\u2009%. Laccase\/histidine system could improve the physical properties of recycled fiber, alleviate fiber decay, which are of great significance to solve the resource shortage and environment pollution of the paper-making industry.<\/jats:p>","DOI":"10.1515\/npprj-2018-0079","type":"journal-article","created":{"date-parts":[[2019,3,15]],"date-time":"2019-03-15T09:03:23Z","timestamp":1552640603000},"page":"211-217","source":"Crossref","is-referenced-by-count":2,"title":["The influence of laccase\/histidine system on the properties of OCC pulp fibers, and of handsheets made thereof"],"prefix":"10.1515","volume":"34","author":[{"given":"Yangmei","family":"Chen","sequence":"first","affiliation":[{"name":"College of Natural Resource and Environment , 12526 South China Agricultural University , Guangzhou , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiqian","family":"Mai","sequence":"additional","affiliation":[{"name":"College of Natural Resource and Environment , 12526 South China Agricultural University , Guangzhou , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qitang","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Natural Resource and Environment , 12526 South China Agricultural University , Guangzhou , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiaqian","family":"Kang","sequence":"additional","affiliation":[{"name":"College of Natural Resource and Environment , 12526 South China Agricultural University , Guangzhou , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Natural Resource and Environment , 12526 South China Agricultural University , Guangzhou , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wanqi","family":"Mai","sequence":"additional","affiliation":[{"name":"College of Natural Resource and Environment , 12526 South China Agricultural University , Guangzhou , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zebin","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Natural Resource and Environment , 12526 South China Agricultural University , Guangzhou , China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2019,3,15]]},"reference":[{"key":"2023040101312472463_j_npprj-2018-0079_ref_001_w2aab3b7b4b1b6b1ab1b5b1Aa","doi-asserted-by":"crossref","unstructured":"Alexandre, G., Zhulin, I.B.
