Arthrobacter (from the Greek, "jointed small stick”) is a
Description
Arthrobacter can be grown on mineral salts pyridone broth, where colonies have a greenish metallic center on incubated at 20 °C (68 °F). Under the microscope, Arthrobacter appear as rods when rapidly dividing, and cocci when in stationary phase. Dividing cells may also appear as chevrons ("V" shapes). Other notable characteristics are that it can use pyridone as its sole carbon source, and that its cocci are resistant to desiccation and starvation.
Use in industry
Arthrobacter, like other bacterial genera including Brevibacterium, Microbacterium, and Corynebacterium are used for industrial production of L-glutamate. In industrial applications, Arthrobacter is often grown with low-cost sugar sources such as cane or beet molasses, starch hydrolysates from corn or cassava tubers, or tapioca. Along with sugar, ammonia and ammonium salts are added as a nitrogen source. The vitamins, minerals, and some other types of nutrients can be provided by adding corn steep liquour.
Other uses
Various Arthrobacter species have been investigated for other commercial applications.
Arthrobacter sp. H65-7 produces the enzyme inulase II that converts inulin into the medically relevant nutrient difructose anhydride.[4]
The enzyme Alu obtained from Arthrobacter luteus is able to cleave Alu sequences which is frequently repeated in human DNA.[5]
