Effects of pretreatment on the microcharacterization and fermentation of bamboo shoot shells

Abstract

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.
