'Candidatus Magnetoglobus multicellularis', a multicellular, magnetotactic prokaryote from a hypersaline environment.
Phylogenetic analysis and phenotypic characterization were used to assign a multicellular magnetotactic prokaryote the name 'Candidatus Magnetoglobus multicellularis'. 'Candidatus Magnetoglobus multicellularis' lives in a large hypersaline coastal lagoon from Brazil and has properties that are unique among prokaryotes. It consists of a compact assembly or aggregate of flagellated bacterial cell...
متن کاملSpatiotemporal distribution of the magnetotactic multicellular prokaryote Candidatus Magnetoglobus multicellularis in a Brazilian hypersaline lagoon and in microcosms.
Candidatus Magnetoglobus multicellularis is an unusual morphotype of magnetotactic prokaryotes. These microorganisms are composed of a spherical assemblage of gram-negative prokaryotic cells capable of swimming as a unit aligned along a magnetic field. While they occur in many aquatic habitats around the world, high numbers of Ca. M. multicellularis have been detected in Araruama Lagoon, a larg...
متن کاملSalinity dependence of the distribution of multicellular magnetotactic prokaryotes in a hypersaline lagoon.
Candidatus Magnetoglobus multicellularis is an unusual magnetotactic multicellular microorganism composed of a highly organized assemblage of gram-negative bacterial cells. In this work, the salinity dependence of Ca. M. multicellularis and its abundance in the hypersaline Araruama Lagoon, Brazil were studied. Viability experiments showed that Ca. M. multicellularis died in salinities upper tha...
متن کاملMagnetic optimization in a multicellular magnetotactic organism.
Unicellular magnetotactic prokaryotes, which typically carry a natural remanent magnetic moment equal to the saturation magnetic moment, are the prime example of magnetically optimized organisms. We here report magnetic measurements on a multicellular magnetotactic prokaryote (MMP) consisting of 17 undifferentiated cells (mean from 148 MMPs) with chains of ferrimagnetic particles in each cell. ...
متن کاملA Preliminary Report on the Isolation and Identification of Magnetotactic bacteria from Iran Environment
Several species of Magnetotactic bacteria have been discovered recently. These bacteria synthesize intracellular magnetic nanoparticles in specific sizes and shapes and arrange them in chains. These particles called magnetosomes and can be used for drug-delivery, cell-targeting and hyperthermia. Magnetotactic bacteria navigate along the magnetic field; this process is known as ‘magnetotaxis’ wh...
