A river-ecosystem is strongly affected by human activities. The pollutants discharged into a river from human activities may destroy the ecosystem of the river. Microorganisms in rivers (including suspended and sessile microorganisms) play key roles in degrading the pollutant and therefore in preventing the river ecosystem from being destroyed. To establish suitable measures for the protection and restoration of a riverecosystem, the characteristics of the microorganisms in that ecosystem should be understood exactly. Many studies have been carried out on the role of microorganisms in river-ecosystems and the relationship between water quality and suspended microorganisms or Analysis of the differences in microbial community structures between suspended and sessile microorganisms in rivers based on quinone profile
