| Abstract: | Magnetotactic
bacteria (MTB), Magnetospirillum
magnetotacticum (MS-1) were successfully grown in
modified magnetic spirillum growth medium (MSGM) at normal laboratory
environment. About five-time increase in the bacterial yield was achieved in
the modified MSGM medium without compromising their magnetosomes properties.
Transmission electron and scanning electron microscopy (TEM & SEM) were
used for morphological study of MTB. Energy dispersive analysis of X-rays (EDAX)
and vibrating sample magnetometer (VSM) techniques, respectively, were used to
elucidate the phase and magnetization in the bacterially synthesized
magnetosomes. These studies were important to cross-check the morphology of
magnetosomes, as the formation of magnetosomes was highly sensitive to
environmental conditions. |
