Cell Morphology and Features
editArthrobacter alkaliphilus is a non-motile, Gram-positive bacteria that demonstrates a rod-coccus growth cycle. This was first observed upon culture of bacteria in Genus Arthrobacter where a young culture demonstrated an irregular rod shape which was replaced in older cultures by a coccoid form.[5] When those older cultures were placed in a new media they again produced irregular rod shapes. It is this characteristic that makes Arthrobacter bacteria unique and hard to identify. In a culture of an Arthrobacter alkaliphilus colony scientists observed a round, convex, and glossy appearance with entire margins and a light yellow color. After 2–7 days the culture shows mostly coccoid cells that are 0.6–1.0 micrometers in diameter. In most Arthrobacter bacteria the fatty acids found are primarily iso- and anteiso-branched which refers to a branch on the antepenultimate carbon atom of a saturated fatty acid chain.[6] Initial testing of bacteria found in volcanic rock showed that the major fatty acid was anteiso-C15 : 0 and the major amino acid present in the cell wall peptidoglycan was l-lysine a common amino acid used in the structure of many living organisms. Biochemical characteristics were assessed by Linxian Ding, Taketo Hirose, and Akira Yokota showing results for alkaline and a number of enzymes including; acid phosphatase, catalase, esterase lipase C8, leucine arylamidase, valine arylamidase, typsin, naphthol-AS-BI-phosphohydrolase, alpha- and beta-glucuronidase, alpha-glucosidase, alpha-mannosidase, pyrazinamidase, pyrrolidonyl arylamidase, and urease.

Metabolic details
editThe BacDive is a worldwide database that uses cultured data demonstrating Arthrobacter’s metabolism and physiology. Arthrobacter is a gram-positive bacterium and it requires oxygen to fully utilize its carbon diet. It can consume glucose, lactose, maltose, mannitol, and ribose.[9] Arthrobacter alkaliphilus is a subtype of Athrobacter that can degrade lindane and use it as a carbon source. It utilizes acid phosphatase, alkaline phosphatase, alpha-galactosidase, catalase, Pyrazinamidase, and urease. It is commonly found in volcanic rock at an optimal pH of 8.5, 3-7% NaCl, and a temperature of 30 °C. It cannot form spores for reproduction.[10]
Relevance to broader system
editThe genus Arthrobacter is a member of the family Micrococcaceae and compared to other genera of the family, it contains the highest number of species. This contributes to the fact that species within Arthrobacter are metabolically versatile and can be found in diverse environments. Understanding this genus is essential to understanding the impact each has on its environment.[5] The primary impact each has is its ability to degrade different environmental pollutants. One such pollutant, lindane, has shown to accumulate in the adipose tissue of different organisms and is very toxic to aquatic organisms and somewhat toxic to mammals and birds. Arthrobacter Alkaliphilus’ ability to degrade lindane can then have a major impact on its ecosystem.
