Article Abstract:
Microbial communities in the biological filter and waste sludge compartments of a marine recirculating aquaculture system are examined to determine the presence and activity of anaerobic ammonium-oxidizing (anammox) bacteria. It is the first identification of anammox-related sequences in a marine recirculating aquaculture filtration system, and the findings provide a foundation for incorporating this important pathway for complete nitrogen removal in such systems.

Article Abstract:
The study about the persistence and transmission of Aeromonas in a duckweed aquaculture-based hospital sewage water treatment plant in Bangladesh indicate that certain phenotypical and genotypical stable clonal lineages of Aeromonas might spread from the hospitalized children suffering from diarrhea to fish produced for human consumption through the sewage water treatment system.

Article Abstract:
The survival of an aroA mutant of Aromonas hydrophila in aquatic microcosms prepared from fish water tanks is described. The results help to understand the behavior of aroA strain in natural environments and suggest that the inactivation of the aroA gene may be beneficial for the safety of this live vaccine for aquacultures.
