摘要：Diatom species Karayevia amoena and three species of Halamphora coffeaeformis were used to colonize open-cell porous UHMWPE scaffolds with ca. 70 vol.% porosity during 20-days laboratory exposure to the media drawn from the Baltic Sea (Baltiysk, Russia) and Arabian sea (Mumbai, India), respectively. The nature of diatomic colonization of various surface relief elements were studied by means of SEM imaging of dried specimens. Individual diatoms, their aggregates and extended colonies occupy ‘valley’ and ‘hill’ elements of relief. forming single and multi-layer structures. Karayevia amoena diatoms strongly attach themselves to the substrate, with the evidence of polymer substrate deformation seen in the vicinity of diatom exoskeleton. The mechanisms of diatom proliferation and the formation of intriguing 3D “pot-shaped” colonies are examined in view of the force interaction at the diatom-substrate interface.
