聚磷菌Accumulibacter各进化枝研究进展

Gongye shui chuli, 2017
Accumulibacter是强化生物除磷（EBPR）系统中负责生物除磷的主要聚磷菌，其包含多个进化枝。文章就Accumulibacter各进化枝的研究现状进行了阐述和总结，包括进化枝的分类方式以及各进化枝对电子受体、碳源、温度等影响因素的选择特异性。根据Accumulibacter不同进化枝的生理特性，分析了不同进化枝的反硝化吸磷能力以及对PHA合成途径和厌氧化学计量数的影响。

Dominant and novel clades of Candidatus Accumulibacter phosphatis in 18 globally distributed full-scale wastewater treatment plants [PDF]

Here we employed quantitative real-time PCR (qPCR) assays for polyphosphate kinase 1 (ppk1) and 16S rRNA genes to assess relative abundances of dominant clades of Candidatus Accumulibacter phosphatis (referred to Accumulibacter) in 18 globally ...

Metabarcoding reveals unique microbial mat communities and evidence of biogeographic influence in low‐oxygen, high‐sulfur sinkholes and springs

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Groundwater‐fed underwater sinkholes and springs create habitats with high‐sulfur, low‐oxygen conditions. Multi‐marker metabarcoding was used to describe microbial mat communities in these extreme aquatic habitats. Unique bacterial and diatom communities were found in five springs in Michigan and Florida, with water parameters and biogeography ...

Assessing the performance of polyphosphate accumulating organisms in a full‐scale side‐stream enhanced biological phosphorous removal

Water Environment Research, Volume 96, Issue 1, Page 1-148, January 2024.
A full‐scale side‐stream enhanced biological phosphorous removal (S2EBPR) was monitored to examine the correlation between polyphosphate accumulating organisms (PAOs) activity and seasonal/operational parameters, analyze the microbial community, and assess S2EBPR feasibility.

NADH-driven poly-3-hydroxybutyrate accumulation in Escherichia coli: Data from enzymatic assays and oxygen-limited continuous cultures

Data in Brief, 2020
Biosynthesis of poly-3-hydroxybutyrate (PHB) as a fermentation product enables the coupling of growth and product generation. Moreover, the reduction of oxygen supply should reduce operative cost and increase product yield.

Nitrous oxide production, truncated denitrification pathways, and omics-informed process modeling in a denitrifying phosphorus removal bioprocess

Water Research X
Nitrous oxide (N2O) is a potent greenhouse gas produced as an unintentional, undesired byproduct in nitrogen removal bioprocesses, particularly in shortcut nitrogen removal or simultaneous nitrification-denitrification configurations that produce nitrite
