Sphingomonas aliaeris is a gram negative, rod-shaped, motile and non-spore forming bacterium. S.aliaeris form red, convex, circular, shiny colonies with a diameter of <1 mm and its cells have a diameter of 1.5x0.9 µm. This species is a chemoheterotroph meaning that it breaks down complex organic compounds to use as energy. It can degrade chemicals such as hydrocarbons, synthetic chemicals, and pesticides. Similar to other species in the Sphingomonas genus, this species contains sphingoglycolipids and ubiquinone Q-10 as its major respiratory quinone (Heidler 2021).

Sphingomonas Aliaeris
Description and Significance
Sphingomonas aliaeris is a species of gram-negative, obligate aerobe bacteria that appears as rod-shaped (bacilli) cells under a microscope. Typically found in soil, water, and plant surfaces, it belongs to the genus Sphingomonas, which is known for several different ecological roles. For instance, this species is very metabolically flexible, and it can degrade many complex organic compounds. It can break down xenobiotics (synthetic chemicals), aromatic hydrocarbons, and organic pollutants like pesticides or herbicides. It is involved in many metabolic processes, so its importance is relevant to the cycling of organic matter in ecosystems and potential industrial applications like bioremediation. Overall, it has a strong significance in biotechnology and biodegradation.

Cell Structure, Metabolism and Life Cycle
Sphingomonas aliaeris is a gram negative, rod-shaped, motile and non-spore forming bacterium. S.aliaeris form red, convex, circular, shiny colonies with a diameter of <1 mm and its cells have a diameter of 1.5x0.9 µm. This species is a chemoheterotroph meaning that it breaks down complex organic compounds to use as energy. It can degrade chemicals such as hydrocarbons, synthetic chemicals, and pesticides. Similar to other species in the Sphingomonas genus, this species contains sphingoglycolipids and ubiquinone Q-10 as its major respiratory quinone (Heidler 2021). In addition, this species reproduces by binary fission, resulting into the parent cell dividing into two identical daughter cells.
Ecology and Pathogenesis
Sphingomonas Aliaeris is a psychrotroph that grows best at low temperatures and in high CO2 environments. The bacterium was isolated from pork steak samples packed at 4°C with 75% oxygen and 20% CO2. There is no research on the symbiosis of Sphingomonas Aliaeris, but the Sphingomonas genus often aids in nutrient exchange and pathogen resistance. Sphingomonas Aliaeris has a diverse metabolism, allowing it to break down many organic compounds. This means it contributes to organic matter degradation and recycling within its habitat. It could be helpful in food storage due to it being a psychtrotroph. There is no evidence of the bacterium being pathogenic, and many Sphingomonas species are not.
