Understanding the impact of biofuel-cropping systems on soil biogeochemical processes,especially in relation to C sequestration and nutrient supply,is of paramount importance in assessing long-term sustainability.Although soil bacteria play a critical role in the mediation of these processes,often only surficial soils are assessed for microbial responses in cropping system studies while the deeper soils,and their impact on overall ecosystem function,are left unresolved.In order to address this,we assessed bacterial community composition and soil properties for samples collected at 0-10 cm,10-25 cm,25-50 cm,and 50-100 cm under corn,switchgrass,Miscanthus,and restored prairie,as well as 0-10 cm under six additional biofuel crops at the Kellogg Biological Station in Michigan.

研究在污泥膨胀与不膨胀时城市污水处理厂中细菌与噬菌体丰度的差异.分别在5月份和9月份在包含2个AO工艺和1个A2O工艺的两个城市污水处理厂测其活性污泥中的SV,SVI,MLSS,COD,TN,TP,SS,DO等基本指标；对污水样品中的细菌和噬菌体过滤后分别进行DAPI染色和Sybr Gold染色,通过荧光显微镜对其进行计数,获得其丰度；使用SPSS软件处理数据.5月份SV均高达60％,表明污泥膨胀
近年来,抗生素的环境污染与扩散问题已经成为全球关注的热点.畜禽粪便作为抗生素及抗生素抗性基因的重要储库,若未经处理直接施用则具有潜在的生态环境和人类健康风险.本研究采用传统的好氧堆肥方法,对不同来源的鸡粪、猪粪样品中的四环素类抗生素(四环素、土霉素)残留、四环素类抗性细菌、四环素类抗性基因的动态变化进行了追踪研究.结果表明,畜禽粪便中四环素、土霉素的浓度经堆肥处理后分别减少了74.9％～92.3％
