碱性氧化物预处理玉米秸秆维管柱、皮层和表皮研究(Pretreatment of Micro-column, Cortex and Epidermis of Corn Stover by Alkali Oxide)
玉米秸秆 木质纤维素 预处理
2010/12/29
以玉米秸秆的维管柱、皮层和表皮为材料,分别考察固液比、发酵时间、碱性氧化物浓度和预处理时间对发酵液中还原糖含量以及FPA酶活的影响;通过正交试验进一步优化糖化条件,结果表明,在固液比、发酵时间、碱性氧化物、预处理时间分别为1∶20、5d、1%、3d,1∶15、5.5d、1%、3.5d和1∶15、5d、1%、3d条件下,发酵液中的还原糖含量最高,维管柱、皮层和表皮分别为15.92%、12....
Nitrogen conversion and nitrous oxide hot spots in energy crop cultivation
nitrogen fertilisation level N2O soil flux cultivated and non-cultivated soils perennial and annual plants
2014/2/27
Since 1999, nitrous oxide (N2O) soil emissions from sites cultivated with energy plants have been measured by gas chromatography and gas flux chambers in experimental fields. The main aim of this stud...
