Abstract EN
Pelleting can increase the efficiency of handling and transportation of biomass.
Pretreatment obtains lignin fragments by disrupting the lignocellulosic structure of biomass and ensures the high-quality compressed pellets.
In this study, solid-state fermentation (SSF) is used as a biological method to improve the quality of pellets of oat straw.
SSF of oat straw using Trametes versicolor 52J (TV52J) and Phanerochaete chrysosporium (PC) was conducted.
Response surface methodology (RSM) was employed by using a four-factor, three-level Box–Behnken design with fermentation time (days), moisture content (%), particle size (mm), and fermentation temperature (°C) as independent parameters.
Pellet density, dimensional stability, and tensile strength were the response variables.
The optimization options of fermentation time (33.96 and 35 days), moisture content (70%), particle size (150 and 50 mm), and fermentation temperature (22°C) of oat straw pretreated with these two fungal strains were obtained.
The microscopic structural changes of oat straw caused by biological pretreatment were investigated by scanning electron microscopy (SEM).
Observation results of SEM showed that the connection between single fibers became relatively loose, and this was beneficial to improve the physical quality of the pellets.
