aerotactic मीनिंग इन हिंदी

Two different magneto-aerotactic mechanisms known as polar and axial are found in different MTB strains.
The magnetic field provides both an axis and a direction of motility for polar magneto-aerotactic bacteria, whereas it only provides an axis of motility for axial types of bacteria.
Some strains that swim persistently in one direction along the magnetic field ( either north-seeking [ NS ] or south-seeking [ SS ] ) mainly the magnetotactic cocci are polar magneto-aerotactic.
Those MTB that swim in either direction along magnetic field lines with frequent, spontaneous reversals of swimming direction without turning around for example, freshwater spirilla are axial magneto-aerotactic and the distinction between NS and SS does not apply to these bacteria.
