Low temperature decreases the phylogenetic diversity of ammonia-oxidizing archaea and bacteria in aquarium biofiltration systems

Article Abstract:

The phylogenetic diversity and species richness of ammonia-oxidizing archaea (AOA) and bacteria (AOB) are examined with aquarium biofiltration systems. The results have shown that temperature is the main factor affecting the population structure and diversity of AOA and AOB in aquarium biofiltration systems.

Direct detection by in situ PCR of the amoA gene in biofilm resulting from a nitrogen removal process

Article Abstract:

Researchers describe a PCR technique for detecting a single functional gene in a biofilm. The gene is amoA, which is a subunit of the gene coding for ammonia monooxygenase. The technique can be used to assess a biofilm for its ability to remove nitrogen from wastewater.
