基于16S rRNA扩增子测序技术对全球污水处理厂(WWTP)强化生物除磷(EBPR)工艺中微生物群落的研究表明Tetrasphaera是丰度最高的聚磷菌(PAOs)。然而,目前对于Tetrasphaera 如何在 EBPR 中进行选择性富集尚不清楚。本文通过“自上而下”的方法利用复合碳源和低浓度烯丙基硫脲构建了Tetrasphaera富集的EBPR微生物组,其16S序列的丰度在第 113 天可达 40%。Tetrasphaera富集的微生物组具有高的营养物去除效率,可以实现约85% 的磷(P)去除和约80%的氮(N)去除,其污泥灰分中的P回收率相较于普通污水处理厂活性污泥提高了 23.2 倍。研究表明,添加1 mg·L−1 烯丙基硫脲同时促进了 Tetrasphaera PAOs 和 Microlunatus PAOs 的增加,并且显着降低了氨氧细菌Nitrosomonas和PAOs的潜在竞争者 Brevundimonas 和 Paracoccus 的相对丰度,促进了 EBPR 微生物组的建立。16S rRNA 基因分析表明,体系中的EBPR-ASV0001与 Tetrasphaera japonica 的亲缘关系最为相近,其可能代表了一种新的PAOs。本研究为通过烯丙基硫脲促进Tetrasphaera富集的微生物组建立提供了新的认知,或可用于指导未来污水处理系统工艺的升级和优化,从而帮助实现高浓度废水的同步脱氮除磷。

A range of plant species produce root exudates that inhibit ammonia-oxidizing microorganisms. This biological nitrification inhibition (BNI) capacity can decrease N loss and increase N uptake from the rhizosphere. This study sought evidence for the existence and magnitude of BNI capacity in canola ( Brassica napus). Seedlings of three canola cultivars, Brachiaria humidicola(BNI positive) and wheat ( Triticum aestivum) were grown in a hydroponic system. Root exudates were collected and their inhibition of the ammonia oxidizing bacterium, Nitrosospira multiformis, was tested. Subsequent pot experiments were used to test the inhibition of native nitrifying communities in soil. Root exudates from canola significantly reduced nitrification rates of both N. multiformis cultures and native soil microbial communities. The level of nitrification inhibition across the three cultivars was similar to the well-studied high-BNI species B. humidicola. BNI capacity of canola may have implications for the N dynamics in farming systems and the N uptake efficiency of crops in rotational farming systems. By reducing nitrification rates canola crops may decrease N losses, increase plant N uptake and encourage microbial N immobilization and subsequently increase the pool of organic N that is available for mineralization during the following cereal crops.
