Aquaponics incorporate fish culture and hydroponically grown plants into one intensive production system. In this productive system, the microbial community develops everywhere being responsible of carrying out the nutrient between different compartments. Currently, the state of knowledge regarding the dynamics of microbial communities in recirculating aquaponic systems is stilllimited, due to poor understanding of interactions between bacterial population established on different substrates; therefore, in order to clear a number of uncertainties, especially at the level of heterotrophic communities, further studies are required. The present paper assessed the dynamics of heterotrophic microbial communities in recirculating aquaponicsystems. The studyis based on the assessment of activity and, especially, of the metabolic diversity of bacterial community attached to the root area of hydroponically cultivated species. Examination of the data gave the first indications to functional groups of organisms in the different compartments of an experimental aquaponic system.
