28. The number of magnetosomes contained with in each chain has been estimated as 6. It is an average, which is deduced by counting the number of magnetosomes in 100 chains. The average distance between two chains, a ∼100 nm, has been estimated by measuring the distance between the centers of two adjacent chains in 100 chains. The volume of a typical chain of magnetosomes has been calculated, considering that the latter contains 6 magnetosomes with a mean size of 30 nm.
