中文摘要:采用微波和酸/碱预处理玉米芯,研究不同微波功率密度和时间对酸/碱预处理后秸秆糖化的影响。结果表明:微波/碱处理组中获得的还原糖平均为51.71mg,比对照提高了33.82%;微波/酸预处理组中,平均还原糖质量为8.76 mg。酸/碱预处理后进行微波处理,发酵液中的FPA酶活平均为2.23U/mL和10.90 U/mL,分别比对照提高17.26%和35.05%;CMC酶活平均为3.43 U/mL和12.41 U/mL,分别比对照下降15.96%和提高34.32%。微波处理对碱预处理后的玉米芯优于对酸预处理后的效果。
Key Words:
Abstract:Pretreatment of corn cob was carried out by microwave/alkali and microwave/acid, including different power densities and time of microwave pretreatment. The results showed that average weight of reducing sugar received by microwave/alkali pretreatment was 51.71mg, over 33.82% than the control. And the weight was 8.76mg by microwave/acid. Acid/alkali pretreatments were followed by microwave treatment. Average FPA activities were 2.23U/mL and 10.90U/mL in fermentation fluid, respectively, increasing 35.05% and 17.26% compared with the control. Meantime average CMC activities were3.43 U/mL and 12.41 U/mL, respectively, decreasing 15.96% and increasing 34.32% respectively compared with the control. Alkali pretreatment of corn cob followed by microwave was better than the acid pretreatment.

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.
