Study on solid-state fermentation and purification of cellulase from Penicillium sp.T24-2 [PDF]
, 2008 青霉T24-2是一株具有较高固态发酵产酶能力的菌株。本文通过对青霉T24-2的固态发酵条件进行研究，确定了该菌株的最佳产酶条件为：固体培养基蔗麸比为4:6，添加0.2%尿素为氮源，按10%接种量接种种龄为18h的菌悬液，每250mL三角瓶中固体培养基装瓶量30g（干重10g），pH自然，30℃下培养3d。最佳糖化条件为：曲料比1:3,加水比1:6，在50℃，170r/min条件下糖化18h，最高糖化率可达32.4%，每100g甘蔗渣糖化液经酿酒酵母发酵后，酒精产量可达11.3g。 甘蔗渣经4 ...

Shuitu Baochi Xuebao, 2022 为明确不同覆盖方式对旱地马铃薯田土壤耗水、耗水规律、水分利用效率、产量及产量形成的影响,在陇中半干旱农区设置了玉米秸秆带状双行覆盖(SSM2)、玉米秸秆带状单行覆盖(SSM1)、玉米秸秆全覆盖(SFM)、地膜春覆盖(PMS)和地膜秋覆盖(PMA)5种覆盖方式,以传统露地平作为对照(CK)。结果表明:2年试验中,玉米秸秆带状覆盖和地膜覆盖处理土壤贮水消耗量较CK分别增加13.5,14.8 mm。玉米秸秆带状覆盖能显著提高降水对马铃薯耗水贡献率,不同降雨年型内均以SSM2处理贡献率最高,2年分别为95.6 ...

Study on System of Microbial Hydrogen Production [PDF]
, 2005 利用微生物将自然界中极为丰富的生物质降解为糖类物质，再转化为氢或乙醇等能源物质，对缓解人类目前所面临的能源危机，降低环境污染，实现经济的可持续发展战略等有重要的意义.本研究利用纤维素降解菌株灰绿曲霉（Aspergillusglaucus）XC9将秸秆（稻草粉）降解成糖类物质，并利用产氢微生物产酸克雷伯氏菌（Klebsiellaoxytoca）HP1，将其转化成氢，实现秸秆的综合利用；以曲霉所形成的菌丝球吸附并固定产氢细菌进行连续流产氢，建立了一种适用于连续流制氢过程中产氢细菌截留的新方法 ...

Simulation Study of the Emission of Polycyclic Aromatic Hydrocarbons and Sugar Alcohols from Biomass Burning [PDF]
, 2015 选择水稻、小麦、玉米及棉花秸秆与马尾松枝,采集模拟燃烧时排放的PM2.5,分析PM2.5中多环芳烃(PAHS)和糖醇类化合物的含量,获得PM2.5及负载的两类化合物的排放因子;采用500 W汞灯直接照射收集了PM2.5的尘膜,获得了中、高环PAHS及左旋葡聚糖的光解动力学.结果表明,PM2.5的排放因子介于(2.26±0.60)g·kg-1(马尾松枝)~(14.33±5.26)g·kg-1(玉米秸秆)之间;19种PAHS的排放因子介于(0.82±0.21)Mg·kg-1(马尾松枝)~(11.14±5 ...
