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。

The concentration and components of manure phosphorus (P) are key factors determining potential P bioavailability and runoff. The distribution of P forms in swine, poultry and cattle manures collected from intensive and extensive production systems in several areas of China was investigated with sequential fractionation and a simplified two-step (NaHCO -NaOH/EDTA) procedures. The mean total P concentration, determined by the sequential fractionation procedure of intensive swine, poultry and cattle manure, expressed as g·kg , was 14.9, 13.4 and 5.8 g·kg , respectively, and 4.4 g·kg in extensive cattle manure. In intensive swine, poultry and cattle manure about 73%, 74% and 79% of total P, respectively, was bioavailable (i.e., P extracted by H O and NaHCO ) and 78% in extensive cattle manure. The results indicated the relative environmental risk, from high to low, of swine, poultry and cattle manure. There is considerable regional variation in animal manure P across China, which needs to be considered when developing manure management strategies.

The continued supply of phosphate fertilizers that underpin global food production is an imminent crisis. The rock phosphate deposits on which the world depends are not only finite, but some are contaminated, and many are located in geopolitically unstable areas, meaning that fundamental changes will have to take place in order to maintain food production for a growing global population. No single solution exists, but a combination of approaches to phosphorus management is required not only to extend the lifespan of the remaining non-renewable rock phosphate reserves, but to result in a more efficient, sustainable phosphorus cycle. Solutions include improving the efficiency of fertilizer applications to agricultural land, alongside a better understanding of phosphorus cycling in soil-plant systems, and the interactions between soil physics, chemistry and biology, coupled with plant traits. Opportunities exist for the development of plants that can access different forms of soil phosphorus (e.g., organic phosphorus) and that use internal phosphorus more efficiently. The development of different sources of phosphorus fertilizers are inevitably required given the finite nature of the rock phosphate supplies. Clear opportunities exist, and it is now important that a concerted effort to make advances in phosphorus use efficiency is prioritized.

Phosphorus supply and management in vegetable production systems in China

Vegetable production systems involve high rates of chemical and organic fertilizer applications, leading to significant P accumulation in vegetable soils, as well as a decrease in P use efficiency (PUE), which is one of the key limiting factors in vegetable production. This review introduces the vegetable production systems in China and their fertilization status, and analyzes probable causes of overfertilization of vegetable fields. Poorly developed root systems and high P demand have led to the need to maintain much higher available P concentrations in the root zone for regular growth of vegetables, which might necessitate higher phosphate fertilizer input than the plants require. Research on strategies to improve vegetable PUE and the mechanisms of these strategies are summarized in this review. Increasing the P uptake by vegetables by supplying P during the critical growth stage and effectively utilizing the accumulated P by optimizing the C:P ratio in soils can substantially increase PUE. These advances will provide a basis for improving PUE and optimizing phosphate fertilizer applications in vegetable production through regulatory measures. In addition, some policies are recommended that could ensure the safety of vegetables and improve product quality. This review also aims to improve understanding of P cycling in vegetable fields and assist in the development of best practices to manage P reserves globally.
