A series of experiments was carried out using strips (and nets) of synthetic polymers to increase the contact surface during the cultivation of attached forms of microphytes. We used bands of different composition, as well as with different microrelief surface areas, and a fine-mesh PLA network with an inhomogeneous surface. The experiments were performed on liquid nutrient media in accumulative cultures, and on solid nutrient medium in pure culture. The results showed a number of positive features of such cultivation, based on the selective isolation of individual species and their small combinations from the composition of accumulative cultures, as well as on the effective growth of individual species on specific elements of the microrelief of polymer surfaces. The polymers used were: PET, PP, LDPE, UHMWPE and PLA.
Key words: epipsammon; microepilithon; microepiphyton; cultivation; microalgae; plastic; heterogeneous surface; colonisation
