Diversity of ammonia-oxidizing bacteria in relation to soil environment in Ebinur Lake Wetland

open access: yesBiotechnology & Biotechnological Equipment, 2016
Ammonia oxidation is the first and rate-limiting step of nitrification and is carried out by ammonia-oxidizing bacteria (AOB). Ebinur Lake Wetland, the most representative temperate arid zone wetland ecosystem in China, is the centre of oasis and ...

Metabolic and Proteomic Responses to Salinity in Synthetic Nitrifying Communities of Nitrosomonas spp. and Nitrobacter spp.

open access: yesFrontiers in Microbiology, 2018
Typically, nitrification is a two-stage microbial process and is key in wastewater treatment and nutrient recovery from waste streams. Changes in salinity represent a major stress factor that can trigger response mechanisms, impacting the activity and ...

Microvariation Artifacts Introduced by PCR and Cloning of Closely Related 16S rRNA Gene Sequences [PDF]

open access: yes, 2001
A defined template mixture of seven closely related 16S-rDNA clones was used in a PCR-cloning experiment to assess and track sources of artifactual sequence variation in 16S rDNA clone libraries. At least 14% of the recovered clones contained aberrations.

Aerobic Denitrification Microbial Community and Function in Zero-Discharge Recirculating Aquaculture System Using a Single Biofloc-Based Suspended Growth Reactor: Influence of the Carbon-to-Nitrogen Ratio

open access: yesFrontiers in Microbiology, 2020
In this study, the effect of aerobic denitrification on nitrogen removal was investigated using two zero-discharge biofloc-based recirculating aquaculture systems with representative carbon-to-nitrogen (C/N) ratios of 15 (CN15) and 20 (CN20). Aquaculture

Disturbance-based management of ecosystem services and disservices in partial nitritation-anammox biofilms

open access: yesnpj Biofilms and Microbiomes, 2022
The resistance and resilience provided by functional redundancy, a common feature of microbial communities, is not always advantageous. An example is nitrite oxidation in partial nitritation-anammox (PNA) reactors designed for nitrogen removal in ...

Pilot Scale Application of a Ceramic Membrane Bioreactor for Treating High-Salinity Oil Production Wastewater

open access: yesMembranes, 2022
The offshore oil extraction process generates copious amounts of high-salinity oil-bearing wastewater; at present, treating such wastewater in an efficient and low-consumption manner is a major challenge. In this study, a flat ceramic membrane bioreactor
