In this study, contrary to untreated poplar fiber, processing of alkali-treated poplar fiber was optimized for the enzymatic saccharification. Considering reducing sugar content as the evaluation index, pH, temperature, time, amount of enzyme, and rotational speed of shaker were standardized to optimize the sugar production by enzymatic hydrolysis. Using response surface methodology, the optimum technological condition of enzymatic hydrolysis was found to be utilizing 43 mg cellulase at 46 °C for 50 h. At this, the sugar conversion amount of NaOH or H 2 O 2 -NaOH pretreated poplar was 164.62 mg/g and 218.82 mg/g respectively. It was a corresponding increase of 446.73% or 626.75% than that of poplar fiber without a pretreatment. At a low concentration, metal ions and surfactants promoted the conversion of reducing sugar. Especially, 0.01 g/L Mn 2+ and 0.50 g/L hexadecyl trimethyl ammonium bromide (CTAB) produced the best effect and increased the conversion rate of reducing sugar by 23.62% and 21.44% respectively. Also, the effect of the combination of metal ions and surfactants was better than that of a single accelerator. By improving the enzymatic process, these findings could enhance the utilization of poplar fiber for the production of reducing sugar.

“…The mixture was filtered and the residue was dried in a hot air oven at 105℃ to a constant weight. The lignin and acid and acid detergent fibre (ADF) contents were determined according to the modified method proposed by the NREL, USA [22]. ADF refers to the fibres that could be dissolved by sulphuric acid.…”

This study focuses on the pretreatment and characterization of natural fibers from the bamboo shoot shell(BSS) of Phyllostachys hterocycla, a species of bamboo, to determine their suitability as biorefining materials. The discarded bamboo shoot shell was used for fiber extraction, and the resulting fibers were analyzed for their physical, chemical, and microstructure properties.The Fourier transform infrared spectroscopy,X-ray diffraction spectra and scanning electron microscopy also confirmed that a mixture of sodium hydroxide immersion plus high-pressure steam treatment allowed the cellulose structure to be disrupted, providing more adsorption sites for cellulases.Gas Chromatography Mass Spectrometry (GC-MS) also showed that the internal structure of the fibers was eluted.The cellulaseproduced by (Trichoderma green and Aspergillus niger) reducing sugar yields produced also increased by 267.69% and 250.57%, compared to unpretreated BSS fibers.This strategy may apply to many industries, especially biorefining and lignocellulose biotransformation technology.

This study focuses on the pretreatment and characterization of natural fibers from the bamboo shoot shell (BSS) of Phyllostachys heterocycla to determine their suitability as biorefining materials. The discarded bamboo shoot shell was used as a source of fibers, which were analyzed for their physical, chemical, and microstructure properties. Fourier transform infrared spectroscopy, X-ray diffraction spectra, and scanning electron microscopy confirmed that a mixture of sodium hydroxide immersion plus high-pressure steam treatment allowed the cellulose structure to be disrupted, providing more adsorption sites for cellulases. Gas chromatography mass spectrometry (GC-MS) also showed that the pretreatment exposed the internal structure of the fibers and that high-mass silicon compounds were present in the eluted solution. After adding the cellulase produced by Trichoderma viride and Aspergillus niger, the reducing sugar yield was increased by 268% and 251%, compared to unpretreated BSS fibers. This strategy may apply to many industries, especially biorefining and lignocellulose biotransformation technology.
