N-Methyl-2-pyrrolidone pre-treatment of lignocellulose for high lignin yield and cellulose digestibility
Biomass Conversion and Biorefinery - Tập 14 - Trang 5435-5446 - 2022
Md Khairul Islam, Jianyu Guan, Shazia Rehman, Raffel Dharma Patria, Chuanshuang Hu, Litao Guan, Shao-Yuan Leu, Arun K. Vuppaladadiyam
In the present study, we discovered a new N-methyl-2-pyrrolidone (NMP) pretreatment solvent with an excellent lignin solubility and preserved β-O-4 linkages available in the original lignin structure. The results indicate that the formation of 4-methylamino butyric acid in NMP pretreatment system increased the polarity of the solvent system. The increased polarity synergistically increased the lig...... hiện toàn bộ
Lactic acid production from different sources of organic solid waste: evaluation of the inoculum type and operational optimization
Biomass Conversion and Biorefinery -
Edith Villanueva-Galindo, Marisol Pérez-Rangel, Iván Moreno‐Andrade
AbstractThis work aimed to evaluate the effect of the sources of organic solid waste on lactic acid (HLa) production. Organic fractions from cafeteria (CW), market (MW), and recycling plant (RW) wastes were used as substrates. HLa production during the self-fermentation of CW, MW, and RW, as well as during the fermentation of each substrate with anaerobic sludge (C...... hiện toàn bộ
Concurrent activation and surface modification (CAM) process to produce surface-modified palm kernel shell-derived activated carbon (PKSdAC)
Biomass Conversion and Biorefinery -
Jia Yen Lai, Jiuan Jing Chew, Lock Hei Ngu
AbstractActivated carbon production via chemical activation followed by surface functionalization with metal groups aims to achieve surface functionalization for CO2, aromatic/metallic organic compounds, and dye adsorption. The prepared activated carbon possesses a porous structure containing metal functional groups with adsorptive properties. ...... hiện toàn bộ
Removal of Cibacron Blue P-3R (RB 49) dye from aqueous solution using chemo-physically activated biochar from Agave fiber waste
Biomass Conversion and Biorefinery - Tập 13 - Trang 225-235 - 2021
Kahina Bouhadjra, Wahiba Lemlikchi, Samuel Mignard
This paper presents the use of Agave leaves for the removal of an anionic dye Cibacron Blue P 3R (CB) from aqueous solution. The work reports the preparation of activated material (ALa) by impregnation with H3PO4 and carbon fibers (ALc) by pyrolysis at 800°C, from Agave leaves (AL). The materials were characterized by potentiometric titrations, scanning electron microscope, thermogravimetric analy...... hiện toàn bộ
Enhancement of Kraft lignin molecular relaxation based on laccases from Pycnoporus sanguineus produced in instrumented bioreactors
Biomass Conversion and Biorefinery - Tập 13 - Trang 7139-7150 - 2021
Evanildo F. Souza, Douglas F. Passos, Felipe Souto, Verônica M. A. Calado, Nei Pereira
This study has been focused on obtaining fungal laccases and structural modification of lignin by enzymatic action in laccase-ABTS system, mainly reducing molecular stiffness. The best specific aeration rate in bubble column reactor is 0.67 vvm, with 3260 U/L laccase activity, and enzymatic activity increased by 60% in stirred tank reactor. Enzymatic cocktail has been concentrated in a hollow fibe...... hiện toàn bộ
