Many positive bacteria are major contributors to the breakdown of nutrients that can be readily absorbed by their tissue. Conclusion From the different functionalities in an Aquaponics system, it can be shown that each component would contain a different bacterial community. Samples from the biofilter, plant roots and periphyton will largely contain the same genera, but the abundance of each will varied within the individual samples. A more thorough characterization of microbial communities, when possible down to the species level, linked with biochemical and system parameters, including more sampling sites, will be required to be able to link up the community with its physiological role in an Aquaponics system.
