Arthrobacter luteus (ALU) is a species of gram-positive bacteria in the genus Arthrobacter. A. luteus is facultatively anaerobic, pleomorphic, branching, non-motile, non-sporulating, non-acid-fast, catalase-positive, and rod-shaped (0.6–1.0 μm × 0.8–10.0 μm).[1]
A restriction endonuclease enzyme is extracted from the bacterium and acts at the centre of a palindromic tetranucleotide sequence to give even-ended duplex DNA fragments phosphorylated at the 5'-end. The restriction site Alu-I itself is a 4-base cutter: AG/CT.[2] The Alu retrotransposon is named after the bacterium's abbreviation. The bacterium is also used to produce zymolyase,[3] which can degrade yeast cell wall.
Arthrobacter luteus was isolated from brewery sewage in research done in Takasaki, Japan in 1969. The team studied the bacteria isolated taxonomically and found them to be gram-positive, facultatively anaerobic, pleomorphic, branching, non-motile, non-sporulating, non-acid-fast, and catalase-positive rods. The bacteria also reduced nitrate, hydrolyzed starch and liquefied gelatin along with producing acids from carbohydrates. They then compared the isolated bacteria with 18 other strands of similar microorganisms and found to be in the genus Arthrobacter, but no specific species was corresponded. Thus, the name "Arthrobacter luteus" was given to the isolates.[4]
