This dataset includes laboratory data collected to determine the effects of formaldehyde on nitrification processes in biofilters of recirculating aquaculture systems (RAS). Data from the laboratory studies were used to inform methods used to conduct field trials in a pilot and commercial-scale RAS. Biofilter nitrification was monitored by measuring the levels of total ammonia nitrogen, nitrite, and nitrate in experimental aquaria containing a small biofilter before and after formaldehyde was applied to the test system.

This dataset includes data collected to determine the effects of formaldehyde on nitrification processes in biofilters of recirculating aquaculture systems (RAS) from two field trials. Biofilter nitrification was monitored by measuring the levels of total ammonia nitrogen, nitrite, and nitrate in experimental aquaria containing a small biofilter before and after formaldehyde was applied to the test system.

This dataset includes laboratory data collected to determine the effects of hydrogen peroxide on nitrification processes in biofilters of recirculating aquaculture systems (RAS). Data from the laboratory studies were used to inform methods used to conduct field trials in pilot- and commercial-scale RAS. Biofilter nitrification was monitored by measuring the levels of total ammonia-nitrogen, nitrite-nitrogen, and nitrate-nitrogen in experimental aquaria containing a small biofilter before and after hydrogen peroxide was applied to the test system. There are 4 excel workbooks associated with this data set: RASHP Range finding Trial.csv, RASHP Definitive Trial.csv, Hydrogen Peroxide Lab Studies.csv, and DO after HP addition.csv

This data set is associated with an administrative report submitted to the U.S. Food and Drug Administration Center for Veterinary Medicine (CVM). The project goal was to determine the effects of hydrogen peroxide on the microflora of recirculating aquaculture systems (RAS). There are few aquaculture drugs approved for use in RAS and the CVM will evaluate findings from the study to determine if hydrogen peroxide would be safe to use in RAS.

These data were collected to determine the effect of nitrapyrin, a commercial nitrification inhibitor, on nitrification by a diverse nitrifier-enriched microbial (NEM) community. The NEM community was originally collected from an aquaculture pond in Columbia, Missouri and cultured in HEPES-buffered, minimal mineral salts media, supplemented with a nominal dose of 2 milligrams per liter ammonia-nitrogen, added as ammonium-sulfate. NEM were exposed to nitrapyrin (0 to 32 micrograms per liter) for 192 hours. Before dosing, the nitrapyrin was dissolved in dimethyl sulfoxide (DMSO). After dosing, the DMSO concentration in the flasks was 0.1 percent volume to volume. Ammonia, nitrite, nitrate, pH, dissolved oxygen, temperature, water hardness, conductivity, alkalinity, turbidity, and nitrapyrin were monitored at intervals during the experiment.

SOUR and qPCR data. This dataset is associated with the following publication: Kapoor, V., M. Elk, and X. Li. Inhibitory effect of cyanide on wastewater nitrification determined using SOUR and RNA-based gene-specific assays. Letters in Applied Microbiology. Blackwell Publishing, Malden, MA, USA, 63(2): 155-161, (2016).

Data describe the results of a controlled laboratory mesocosm experiment evaluating the influence of a nitrifier enriched microbial community on silver carp (Hypophthalmichthys molitrix) milt eDNA degradation. Parameters described include the concentration results, limit of detection, and limit of quantification of two silver carp specific quantitative PCR assays and water chemistry results of experimental mesocosms.

There is no data as no experiments were conducted (literature review). This dataset is associated with the following publication: Li , X., V. Kapoor , C. Impellitteri , and K. Chandran.
