Analysis of microbial population dynamics in a partial nitrifying SBR at ambient temperature.

abstract：:Flagella occur on many prokaryotes, which primarily propel cells to move from detrimental to favorable environments. A variety of species-specific flagellation patterns have been identified. Although it is presumed that for each of these flagellated microorganisms, an evolutionarily fixed flagellation pattern is favor...
