【 摘 要 】

To reuse waste wood bioresources and determine the factors required for the growth of Lentinus edodes, Quercus baronii wood bioconversion during the artificial cultivation of L. edodes was characterized by X-ray diffraction (XRD), TG, FT-IR, and TD-GC-MS. Mycelia were observed to grow in wood if cellulose was sufficiently degraded and wood extractives were adequately retained. L. edodes grew in wood if the extractives, cellulose, hemicellulose, and lignin maintained a stable quality ratio. Mycelium and L. edodes grew in samples with high cellulose crystallinity. FT-IR spectra showed that L. edodes grew as the intensity of absorbance associated with unconjugated C=O stretching decreased. TG curves suggested that the samples with lower weight loss were suitable for mycelium, but those with higher weight loss were suitable for L. edodes. TD-GC-MS indicated that the samples containing more phenol derivatives and less acetic acid were suitable for mycelium; the opposite trends were observed for L. edodes.
