Engineering microalgae for water phosphorus recovery to close the phosphorus cycle

Plant Biotechnology Journal, Volume 21, Issue 7, Page 1373-1382, July 2023., 2023
Summary As a finite and non‐renewable resource, phosphorus (P) is essential to all life and crucial for crop growth and food production. The boosted agricultural use and associated loss of P to the aquatic environment are increasing environmental pollution, harming ecosystems, and threatening future global food security.

Changes in BNR Microbial Community in Response to Different Selection Pressure

Nitrogen, 2021
This study investigated structural changes in microbial community of biological nutrient removal (BNR) in response to changes in substrate composition (ammonium and phosphate), redox condition, and morphological characteristics (flocs to granules), with ...

N2‐fixation can sustain wastewater treatment performance of photogranules under nitrogen‐limiting conditions

Biotechnology and Bioengineering, Volume 120, Issue 5, Page 1303-1315, May 2023., 2023
In this study, photogranules were cultivated under nitrogen‐replete and nitrogen‐limiting conditions. Despite nitrogen limitation, photogranules maintained wastewater treatment performance by means of N2‐fixation. N2‐fixation was mainly attributed to filamentous cyanobacteria that are highly abundant in the microbial community and play an important ...

Wastewater treatment potential, light penetration profile and biomass settling performance of a photo‐sequencing batch reactor

Journal of Chemical Technology &Biotechnology, Volume 98, Issue 2, Page 346-356, February 2023., 2023
Abstract BACKGROUND The performance of microalgal and bacterial systems devoted to wastewater treatment might be limited by the poor settling of microalgal biomass and the inhibition of nitrifying bacteria under high irradiance conditions. This work implemented a photo‐sequencing batch bioreactor (PSBR) treating medium‐ and low‐strength wastewaters ...

Integrated Methods for Household Greywater Treatment: Modified Biofiltration and Phytoremediation

Journal of Environmental and Public Health, Volume 2023, Issue 1, 2023., 2023
Most countries around the world have experienced water scarcity in recent decades as fresh water consumption has increased. However, untreated wastewater is routinely discharged into the environment, particularly in developing countries, where it causes widespread environmental and public health problems.

Comparative analysis of floc characteristics and microbial communities in anoxic and aerobic suspended growth processes

Water Environment Research, Volume 94, Issue 12, December 2022., 2022
This paper investigated that how an anoxic suspended growth process would differ from a conventional aerobic counterpart in floc characteristics, microbial diversity, temporal dynamics, and community assembly processes. We also revealed potential limitations with the elimination of aeration in the suspended growth for the biological nutrient removal ...

The microbial community in a high-temperature enhanced biological phosphorus removal (EBPR) process

Sustainable Environment Research, 2016
An enhanced biological phosphorus removal (EBPR) process operated at a relatively high temperature, 28 °C, removed 85% carbon and 99% phosphorus from wastewater over a period of two years.

Investigating the use of anaerobically stored carbon in post‐anoxic denitrification

Water Environment Research, Volume 94, Issue 6, June 2022., 2022
Denitrification via internally stored carbon is represented in a five‐stage nutrient removal process. The carbon source (illustrated in purple) is stored intracellularly during the anaerobic phase. During the post‐anoxic phase, this stored carbon is used as the carbon source for denitrification. Abstract Significant methanol savings are hypothesized to

Disentangle genus microdiversity within a complex microbial community by using a multi‐distance long‐read binning method: example of Candidatus Accumulibacter

Environmental Microbiology, Volume 24, Issue 4, Page 2136-2156, April 2022., 2022
Summary Complete genomes can be recovered from metagenomes by assembling and binning DNA sequences into metagenome assembled genomes (MAGs). Yet, the presence of microdiversity can hamper the assembly and binning processes, possibly yielding chimeric, highly fragmented and incomplete genomes.
