BACTERIUM XYLINUM Meaning and
Definition
-
Bacterium xylinum, also known as Acetobacter xylinum, is a species of Gram-negative, rod-shaped bacteria that belongs to the family Acetobacteraceae.
In terms of morphology, Bacterium xylinum is typically characterized as non-motile and aerobic. Its colonies form clear to whitish, convex, and glossy colonies on agar plates. This bacterium is commonly found in environments with a high sugar content, such as fruits, flowers, and fermenting fruits, though it is also present in fermented food and certain drinks.
Bacterium xylinum is particularly renowned for its ability to produce a complex carbohydrate known as bacterial cellulose. It secretes and organizes cellulose fibrils extracellularly, leading to the formation of a thick, gelatinous biofilm. This trait has found widespread industrial applications, including the production of cellulose-based materials for various purposes, such as wound dressings, scaffolds for tissue engineering, and even high-strength textiles.
Furthermore, Bacterium xylinum plays a crucial role in the process of vinegar production. It converts ethanol into acetic acid through the action of the enzyme known as alcohol dehydrogenase, making it an integral part of the vinegar fermentation process.
While Bacterium xylinum is generally considered non-pathogenic, it should be noted that some strains have been associated with opportunistic infections, primarily in immunocompromised individuals. However, its overall utility and industrial significance make this bacterium of great interest in various fields, including biotechnology, materials science, and food production.
Etymology of BACTERIUM XYLINUM
The etymology of the word "Bacterium xylinum" can be broken down as follows:
1. Bacterium: The word "bacterium" itself comes from the Greek word "baktērion", meaning "small rod" or "staff". The Greek term was adopted into Latin as "bacterium", referring to a minute organism or a bacterium.
2. Xylinum: The term "xylinum" is derived from the Greek word "xylon", which means "wood". This word is often associated with the cellulose-producing ability of the bacterium. As "Bacterium xylinum" is known for producing cellulose, the specific epithet "xylinum" was chosen to reflect this characteristic.
