of elements, iron and oxygen. Thus it can be concluded that the magnetic particles are magnetosomes. Generally, it is thought that cellular magnetotaxis is a direct consequence of the cell possessing... magnetic field. Key words: Leptospirillum ferriphilum; strain YSK; SDS; sucrose density gradient; magnetosomes; magnetotaxis 1 Introduction From 1975, there is much interest in finding magne......
-time quantitative reverse transcription-PCR. The microbial formation of magnetosomes and magnetotaxis was also studied under different Fe2+ concentration. The results indicated that ORF numbers... concentration, and the highest expression level at 150-200 mmol/L ferrous was gained. The number of magnetosomes in ATCC 23270 and the magnetotaxis of cells were significantly related to the expression......
