MAGNETOTACTIC BACTERIA Meaning and
Definition
-
Magnetotactic bacteria are a diverse group of microorganisms that possess the unique ability to navigate along magnetic field lines. This remarkable characteristic is attributed to their ability to synthesize a chain of intracellular magnetic particles known as magnetosomes. These magnetosomes are typically composed of magnetite (Fe3O4) or greigite (Fe3S4) and are aligned within the bacterial cell in a single chain, acting like tiny compass needles.
These bacteria exhibit a wide variety of morphological and physiological traits. They can be found in various aquatic environments such as freshwater, marine, and even extreme environments like hydrothermal vents. Magnetotactic bacteria occupy a range of ecological niches, depending on factors like oxygen content, salinity, and magnetic field strength.
The magnetic sense of these bacteria allows them to orient themselves and migrate along the Earth's magnetic field lines. This behavior is believed to aid their survival by allowing them to efficiently move towards regions with favorable environmental conditions, such as optimal oxygen levels or nutrient-rich areas.
The study of magnetotactic bacteria has important implications in different fields of research, including microbiology, geobiology, biotechnology, and nanotechnology. Their unique ability to synthesize and manipulate magnetosomes has sparked interest in potential applications, such as targeted drug delivery systems and magnetic biosensors. Furthermore, studying magnetotactic bacteria can provide insights into the origins of biological magnetism and the evolution of magnetic sensing organisms.

Etymology of MAGNETOTACTIC BACTERIA
The word "magnetotactic bacteria" is derived from several sources:
1. Magnetism: The word "magnet" originated from the Latin word "magnes", which referred to a type of natural magnet found in Magnesia, a region in ancient Greece. The word "magnet" was later combined with the suffix "-o-" (meaning "related to") and the word "tactic" (from the Greek word "taktikos", meaning "arrangement" or "order") to create "magnetotactic", which means "arranged or ordered with respect to magnetism".
2. Bacteria: The term "bacteria" has its roots in the Greek word "bakterion", which means "small rod" or "staff". This term was used to describe the rod-like shapes of some microorganisms.
