Abstract Microbial communities are responsible for biological wastewater treatment, but our knowledge of their diversity and function is still poor. Here, we sequence more than 5 million high-quality, full-length 16S rRNA gene sequences from 740 treatment plants (WWTPs) across the world use to construct ‘MiDAS 4’ database. MiDAS 4 an amplicon variant resolved, reference database with a comprehensive taxonomy domain species level all sequences. We independent dataset (269 WWTPs) show that 4,...
The microbiology of denitrifying enhanced biological phosphorus removal systems has been a subject much debate. question centred on the affinities different types Candidatus Accumulibacter PAOs, type I and II, towards electron acceptors such as oxygen, nitrate nitrite. This study used propionate anaerobic/anoxic/aerobic lab-scale sequencing batch reactor where microbial culture was successfully enriched in organisms (approx. 90%). able to take up using nitrate, nitrite oxygen acceptors,...
Production of medium chain carboxylic acids (MCCA) as renewable feedstock bio-chemicals, from food waste (FW), requires complicated reactor configurations and supplementation chemicals to achieve product selectivity. This study evaluated the manipulation organic loading rate in an un-supplemented, single stage stirred tank steer anaerobic digestion (AD) microbiome towards acidogenic fermentation (AF), thence elongation. Increasing substrate availability by switching a FW with higher COD...
Abstract A comprehensive assessment of full-scale enhanced biological phosphorus removal (EBPR) plants (five plants, 19 independent tests) was undertaken to determine their effectiveness in terms aerobic and anoxic P removal. By comparing parallel uptake tests under only or anoxic-aerobic conditions, results revealed that introducing an stage led overall on average 90% the removed conditions. This achieved with negligible higher PHA glycogen requirements, 30% lower oxygen consumption...
The aim of this study was to identify, quantify and prioritize for the first time sources uncertainty in a mechanistic model describing anaerobic-aerobic metabolism phosphorus accumulating organisms (PAO) enhanced biological removal (EBPR) systems. These wastewater treatment systems play an important role preventing eutrophication metabolic models provide advanced tool improving their stability via system design, monitoring prediction. To end, global sensitivity analysis conducted using...
A reactor was successfully enriched (90% as shown by Fluorescence in situ Hybridization) Defluviicoccus vanus-related organisms presenting a Glycogen Accumulating Organisms (GAO) phenotype. Initial batch tests were performed using anaerobic/aerobic conditions to assess the capacity of different carbon sources utilization frequently abundant wastewater: acetate, propionate, butyrate, valerate and glucose. Acetate propionate totally consumed anaerobic phase well butyrate valerate, though these...
[S,S]-ethylenediamine-N,N'-diglutaric acid (EDDG) has been gaining interest in the industrial sector as a promising chelator. In this study, effective metal complexing capacity of EDDG over wide pH range was modelled and its biodegradability assessed. Results showed that could effectively bind to several metallic ions completely biodegraded after approximately 15 days by un-acclimatized sludge. To confirm biodegradability, an accurate quantification method based on combination liquid...
This dataset was created as a compilation of experimental data in the literature on production medium chain carboxylic acids (MCCAs) by microbial mixed cultures (MMC) fermentation. The intention to provide comprehensive possible that includes majority results available this research area best our knowledge. focus lied MMC-based studies processing complex organic feedstock, yet selected were included synthetic substrates. relevant collected and categorized according bioreactor operation, i.e....
