Variation characteristics of substrate and flora metabolism associated with co-fermentation of coal and corn straw [PDF]
Adding corn straw to the anaerobic fermentation system of coal can significantly increase the gas production of coal-to-biomethane. However, the changes in substrate and microbial metabolism accompanying this combined fermentation are rarely studied. The

Shuitu Baochi Xuebao, 2023 为探索不同降水年型下耕作结合秸秆覆盖措施对旱作马铃薯生育期土壤贮水量、作物耗水特征和产量形成的影响,连续3年在旱作区秋作物收获后通过设置不同耕作方式(免耕、深松、翻耕)结合秸秆覆盖进行大田试验研究。结果表明,经过3年耕作覆盖处理后,免耕、深松结合秸秆覆盖能显著降低0—40 cm层土壤容重,提高土壤有机质含量。保护性耕作结合秸秆覆盖措施可显著提高马铃薯生育期0—200 cm层土壤贮水量,相对欠水年和欠水年马铃薯全生育期土壤贮水量均以深松覆秸秆处理最高,分别较翻耕不覆盖显著提高15.80%和20.80 ...

Screening of high-efficienct strain for degradation cellulose material [PDF]
, 2007 摘要纤维素资源的开发与利用一直是国内外研究的热点，而纤维素的高效降解与糖化是制约纤维素生物质应用的关键。本研究从腐烂稻草、朽木条、土壤和牛粪等样品中分离到6株纤维素降解菌株。通过滤纸崩解试验、刚果红纤维素平板识别以及液体发酵产酶鉴定，筛选到一株分解纤维素能力较强的真菌。经形态观察和18SrDNA基因片断分析，鉴定该菌株为青霉T24-2。对青霉T24-2的液态发酵条件进行研究。菌株在含3％稻草粉、0.25％尿素和无机盐营养液的培养基中发酵4d,自然pH，30℃，130r/min,菌株的CMC酶活 ...
