Aquarium Nitrification Revisited: Thaumarchaeota Are the Dominant Ammonia Oxidizers in Freshwater Aquarium Biofilters
Ammonia-oxidizing archaea (AOA) outnumber ammonia-oxidizing bacteria (AOB) in many terrestrial and aquatic environments. Although nitrification is the primary function of aquarium biofilters, very few studies have investigated the microorganisms responsible for this process in aquaria. This study used quantitative real-time PCR (qPCR) to quantify the ammonia monooxygenase (amoA) and 16S rRNA ge...
متن کاملTemporal and Spatial Stability of Ammonia-Oxidizing Archaea and Bacteria in Aquarium Biofilters
Nitrifying biofilters are used in aquaria and aquaculture systems to prevent accumulation of ammonia by promoting rapid conversion to nitrate via nitrite. Ammonia-oxidizing archaea (AOA), as opposed to ammonia-oxidizing bacteria (AOB), were recently identified as the dominant ammonia oxidizers in most freshwater aquaria. This study investigated biofilms from fixed-bed aquarium biofilters to ass...
متن کاملThe EcoSystem Aquarium Revisited
One way I judge how an article has been received is by how many letters or phone calls I get about it. Judging by the number of requests for more information on the Ecosystem Aquarium Filtration method, developed by Leng Sy, that I have received since writing articles in both Aquarium Fish Magazine (November 1997) and SeaScope (Fall 1997), I really struck a nerve. There are probably a number of...
متن کاملAn introduction to freshwater aquarium plants
Freshwater aquarium plants are one of the most popular components in freshwater aquariums. The aquarium plant trade is a lucrative trade in its producer countries. In fact, the aquarium is a closed and controlled environment that coordination between all its components is necessary to maintain the balance and stability of this small ecosystem. They beautify the interior of the aquarium, moreove...

tion of the object wavefunction in amplitude and phase from the measured data. However, before we can make a measurement of a quantum state we have to prepare that state. In the case of the caesium atom this job was done by the first object pulse. Can we prepare any desired state, that is, a target state? This is an issue that arises in many disciplines — ranging from physical chemistry, throug...
