| 英文摘要 | Multicellular magnetotactic prokaryotes(MMPs) are a group of aggregates composed of 7-45 gram-negative cells synthesizing intracellular magnetic crystals.Although they are thought to be globally distributed,MMPs have been observed only in marine environments in America and Europe.Most MMPs share a rosette-like morphology and biomineralize iron sulfide crystals.In the present study,abundant MMPs were observed,with a density of 26 ind./cm3,in the sediments of a coastal lagoon,Lake Yuehu,in the Yellow Sea.Optical microscopy showed that all of them were rosette shaped with a diameter of 5.5±0.8 mm.Transmission electron microscopy revealed that these MMPs were composed of 10-16 ovoid cells and flagellated peritrichously.High-resolution transmission electron microscopy and energy dispersive X-ray analysis indicated that they biomineralized bullet-shaped magnetite crystals in highly organized parallel chains within which the magnetosomes were oriented in the same direction.This is the first report of MMPs from Asia and demonstrates the ubiquitous distribution of MMPs. |
