BACILLUS SYNXANTHUS Meaning and
Definition
-
Bacillus synxanthus is a species of rod-shaped, gram-positive bacteria from the genus Bacillus. It is characterized by its ability to produce a yellow pigment, which gives it its specific epithet "synxanthus" (syn meaning together and xanthus meaning yellow in Greek), hence the name "Bacillus synxanthus." This bacterium is commonly found in a variety of terrestrial habitats, including soil, decaying organic matter, and plant surfaces.
Bacillus synxanthus is known for its unique physiological and morphological characteristics. It forms yellow, multicellular aggregates known as fruiting bodies, which are composed of multiple interconnected cells. These fruiting bodies are capable of gliding movement, allowing the bacterium to collectively migrate towards more favorable growth conditions. This communal motility is facilitated by thin, long appendages called fibrils that extend from the cell surface, aiding in surface attachment and movement.
The yellow pigmentation produced by Bacillus synxanthus is attributed to a pigment known as xanthomonadin. This pigment not only provides a distinctive coloration but also plays a role in protecting the bacteria from harmful ultraviolet radiation. It has also been suggested that the yellow pigment may have additional functions, such as attracting insects or aiding in cell-to-cell communication within the multicellular aggregates.
While Bacillus synxanthus is not considered a primary human pathogen, it is of interest in the field of microbiology due to its intriguing characteristics and potential applications. Research on this bacterium may contribute to the understanding of bacterial multicellularity, gliding motility, and the production of natural pigments.
Etymology of BACILLUS SYNXANTHUS
The word "Bacillus synxanthus" is a scientific name that consists of two components: "Bacillus" and "synxanthus". Here is the etymology of each component:
1. Bacillus: The term "bacillus" originates from Latin, where it means "small stick" or "rod". It is used to describe a genus of rod-shaped bacteria that are typically found in soil or water.
2. Synxanthus: The term "synxanthus" is a combination of Greek roots. "Syn" means "together" or "with", and "xanthus" means "yellow" in Greek. Therefore, "synxanthus" can be translated as "together yellow" or "yellowish".
Combining both components, "Bacillus synxanthus" refers to a specific species of bacteria that is rod-shaped and has a yellowish coloration.
