This study presented an approach by combining the real-time reverse transcription polymerase chain reaction with the terminal restriction fragment length polymorphism (T-RFLP) to investigate transcriptional responses of ammonia-oxidizing bacteria (AOB) to dimethyl sulfide (DMS) inhibition.

The contribution of ammonia-oxidizing archaea (AOA) to nitrogen removal in wastewater treatment plants (WWTPs) remains unknown. This study investigated the abundance of archaeal (AOA) and bacterial (ammonia-oxidizing bacteria (AOB)) amoA genes in eight of Bangkok's municipal WWTPs.

Abstract Oxygen minimum zones are results of oxygen consumption exceeding the oxygen availability in stratified water columns of the marine environment. We compared the ammonia monooxygenase subunit A (amoA) gene abundance and the diversity of ammonia-oxidising archaea (AOA) in the Arabian Sea (AS) with those of the Bay of Bengal (BoB).

Abstract Ammonia oxidation is an important part of the global nitrogen cycle. Ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) are important players in the ammoxidation process. In this study, 13 sediment samples from the Liaohe estuary were collected in the wet season.

Although the presence and activity of ammonia-oxidation archaea (AOA) and ammonia-oxidation bacteria (AOB) were observed in thermophilic habitats recently, their existence in the geothermal subterranean oil reservoirs is still not available. This study investigated the abundance and distribution of AOA and AOB in the production waters of high ...

The abundance and diversity of amoA genes of ammonia-oxidizing archaea (AOA) and bacteria (AOB) were investigated in ten wastewater treatment systems (WTSs) by polymerase chain reaction (PCR), cloning, sequencing, and quantitative real-time PCR (qPCR). The ten WTSs included four full-scale municipal WTSs, three full-scale industrial WTSs, and three lab-

The effects of earthworms on nitrogen transformation and the responsible functional genes during disposal of sewage sludge and rice straw were investigated in this study. Vermicomposting resulted in the lower pH and total organic carbon (TOC) compared to the control treatment without earthworms.

We previously reported that partial nitrification in the down-flow hanging sponge (DHS) system was satisfactorily accomplished under oxygen-limited conditions [Chuang et al., Water Res., 41, 295-302 (2007)]. In this study, we investigated the microbes that are responsible for the partial nitrification in this unique system by 16S rRNA- and amoA-based ...

Soil from the Amazonian region is usually regarded as unsuitable for agriculture because of its low organic matter content and low pH; however, this region also contains extremely rich soil, the Terra Preta Anthrosol. A diverse archaeal community usually inhabits acidic soils, such as those found in the Amazon.

Summary Ammonia‐oxidizing bacteria and ammonia‐oxidizing archaea are commonly found together in soils, yet the factors influencing their relative distribution and activity remain unclear. We examined archaeal and bacterial amoA gene distribution, and used a novel bioassay to
