|Title:||Enhancement of magnetotactic bacterial yield in a modified MSGM medium without alteration of magnetosomes properties|
Kulkarni, Gauri R
|Abstract:||Magnetotactic bacteria (MTB), <i style="">Magnetospirillum magnetotacticum </i>(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.|
