Table 1 Table summarizing CCB and PCB characteristics after batch cell bank production in terms of production conditions, identity, and purity: (i) the conditions of preparation for CCB and PCB, i.e. medium types and oxygenation, (ii) the parameters used to verify that bacterial identity is maintained while switching from the CCB and PCB, i.e. comparison of cell size, cell morphology, cytometry spectra, number of magnetosomes per cell, mean magnetosome size, magnetosome size distribution, multiplex PCR of MSR1 16S RNA, between CCB and PCB, (iii) the parameters highlighting bacterial purity in PCB and CCB, i.e. bacterial integrity established by cultivating MSR1 bacteria on LB agar plate and observation of a suspension of MSR1 bacteria to verify the absence of contaminants
