The impact of molecular biology on assessment of water quality: advantages and limitations of current techniques [PDF]
, 1997 The advent of molecular biology has had a dramatic impact on all aspects of biology, not least applied microbial ecology. Microbiological testing of water has traditionally depended largely on culture techniques.

Lost in translation: the quest for Nitrosomonas cluster 7‐specific amoA primers and TaqMan probes
Microbial Biotechnology, 2020 Summary The choice of primer and TaqMan probes to quantify ammonia‐oxidizing bacteria (AOB) in environmental samples is of crucial importance. The re‐evaluation of primer pairs based on current genomic sequences used for quantification of the amoA gene ...

Nitrosomonas europaea expresses a nitric oxide reductase during nitrification. [PDF]
, 2004 In this paper, we report the identification of a norCBQD gene cluster that encodes a functional nitric oxide reductase (Nor) in Nitrosomonas europaea. Disruption of the norB gene resulted in a strongly diminished nitric oxide (NO) consumption by cells ...

A mathematical model of bacteria capable of complete oxidation of ammonium predicts improved nitrogen removal and reduced production of nitrous oxide [PDF]
, 2017 The removal of excess nutrients from water ecosystems requires oxidation of toxic ammonium by two types of bacteria; one oxidizes ammonium to nitrite and the other oxidizes nitrite to nitrate.

Community analysis of betaproteobacterial ammonia-oxidizing bacteria using the amoCAB operon [PDF]
, 2009 The genes and intergenic regions of the amoCAB operon were analyzed to establish their potential as molecular markers for analyzing ammonia-oxidizing betaproteobacterial (beta-AOB) communities.

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.Abstract Biofloc technology (BFT) presents a sustainable approach to aquaculture intensification by recycling nutrients and reducing water exchange. However, probiotic supplementation for optimization in emerging species such as redclaw crayfish (Cherax quadricarinatus) remains unexplored. This study investigated how Bacillus subtilis (B.
