The hydrogen bonding of LTTMs observed in 1H NMR tends to disrupt the three-dimensional structure of lignin and further remove the lignin from EFB. Delignification process of EFB strands and EFB powder were performed using standard L-malic acid and cactus malic acid-LTTMs. The recovered cactus malic acid-LTTMs showed higher glucose concentration of 8.07 mg/mL than the recovered L-malic acid LTTMs (4.15 mg/mL). This implies that cactus malic acid-LTTMs had higher delignification efficiency which led to higher amount of cellulose hydrolyzed into glucose. The cactus malic acid-LTTMs-delignified EFB was the most feasible fibers for making paper due to its lowest kappa number of 69.84. The LTTMs-delignified EFB has great potential to be used for making specialty papers in pulp and paper industry. © 2019 Elsevier Ltd date: 2019 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85069587419&doi=10.1016%2fj.biortech.2019.121797&partnerID=40&md5=05310af8ee60dd293dd839c7229f9cec id_number: 10.1016/j.biortech.2019.121797 full_text_status: none publication: Bioresource Technology volume: 290 refereed: TRUE issn: 09608524 citation: Yiin, C.L. and Ho, S. and Yusup, S. and Quitain, A.T. and Chan, Y.H. and Loy, A.C.M. and Gwee, Y.L.
