中文摘要:为研究真菌预处理秸秆的发酵产甲烷特性,采用白腐真菌固态发酵对玉米秸秆进行预处理,考察生物预处理对干黄和青贮玉米秸秆生物降解性及其厌氧发酵产甲烷性能的影响。真菌预处理15 d的干黄玉米秸秆纤维素、半纤维素和木质素降解率为38.3%、42.2%和39.1%,青贮玉米秸秆纤维素、半纤维素和木质素降解率分别为9.9%、23.2%和15.2%,且预处理的青贮和干黄玉米秸秆酶水解还原糖产量分别为195.8 mg/g和67.7 mg/g,表明预处理过程中干黄玉米秸秆的组分降解较多,预处理后保留在青贮玉米秸秆中可利用组分多于干黄玉米秸秆。后续厌氧发酵实验结果表明预处理青贮玉米秸秆发酵21 d的VS产甲烷量为215.5 mL/g, 相对于未处理青贮玉米秸秆提高29.2%,且占60 d总产甲烷量的73.1%,而预处理干黄玉米秸秆产气量未提高;由此可见,通过白腐真菌预处理可以提高青贮玉米秸秆的生物降解性,进一步促进秸秆生物质转化为甲烷。

Abstract:The microbial pretreatment of yellow corn stover and corn stover silage was achieved via the solid state cultivation of white rot fungi. Pretreatment effects on the biodegradability and subsequent anaerobic production of methane were investigated. The white rot fungi pretreatment of yellow corn stover was accompanied by 38.3% cellulose, 42.2% hemicellulose, and 39.1% lignin degradation, while the degradation of corn stover silage was 9.9% cellulose, 23.2% hemicellulose, and 15.2% lignin. The reducing sugar yield of pretreatment yellow corn stover and corn stover silage after enzymatic hydrolysis was 195.8 mg/g and 67.7 mg/g respectively. These indicated much more composition of yellow corn stover was degradated, and more available composition retained in the corn stover silage after pretreated.The results showed that the total VS methane production of pretreated corn stover silage was 215.5 mL/g after 21 d anaerobic digestion,which increased by 29.2% more than the untreated ones and accounting 73.1% for 60 d total methane production. The biogas production of pretreated yellow corn stover was not increased. So microbial pretreatment of corn stover silage by white rot fungi could increase substrate biodegradability, and further stimulate methane production.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
