Epiphytic bacterial community composition on two common submerged macrophytes in brackish water and freshwater
Abstract Background Plants and their heterotrophic bacterial biofilm communities possibly strongly interact, especially in aquatic systems. We aimed to ascertain whether different macrophytes or their habitats determine bacterial community composition. We compared the composition of epiphytic bacter...
