AB  - Magnetotactic bacteria are a heterologous group of motile prokaryotes, ubiquitous 
      in aquatic habitats and cosmopolitan in distribution. Here, we studied the 
      diversity of magnetotactic bacteria in a seawater pond within an intertidal zone 
      at Huiquan Bay in the China Sea. The pond is composed of a permanently submerged 
      part and a low tide subregion. The magnetotactic bacteria collected from the 
      permanently submerged part display diversity in morphology and taxonomy. In 
      contrast, we found a virtually homogenous population of ovoid-coccoid 
      magnetotactic bacteria in the low tide subregion of the pond. They were 
      bilophotrichously flagellated and exhibited polar magnetotactic behaviour. Almost 
      all cells contained two chains of magnetosomes composed of magnetite crystals. 
      Intriguingly, the combination of restriction fragment length polymorphism 
      analysis (RFLP) and sequencing of cloned 16S rDNA genes from the low tide 
      subregion samples as well as fluorescence in situ hybridization (FISH) revealed 
      the presence of a homogenous population. Moreover, phylogenetic analysis 
      indicated that the Qingdao Huiquan low tide magnetotactic bacteria belong to a 
      new genus affiliated with the alpha-subclass of Proteobacteria. This finding 
      suggests the adaptation of the magnetotactic bacterial population to the marine 
      tide.
