What is Arthrobacter used for?
Arthrobacter, like other bacterial genera including Brevibacterium, Microbacterium, and Corynebacterium are used for industrial production of L-glutamate.
Is Arthrobacter Gram-positive or Gram negative?
The genus Arthrobacter includes microorganisms that live in several environmental habitats as soil or aerial surfaces of plants. The organisms are aerobic, Gram-positive coccoid cells. Some species changes the cell morphology from rod to coccoid depending on the age of the culture.
Is Arthrobacter catalase-positive or negative?
The genus Arthrobacter includes a heterogeneous group of aerobic, gram-positive, catalase-positive, nonfermentative coryneform bacteria of high G+C DNA content (18).
What does arthrobacter Globiformis do?
Arthrobacter Globiformis lives in soil, and it can greatly benefits the plants, animals and other living species by breaking down various chemicals which are harmful for lives, including agricultural chemicals, Chromium and other chemicals that can cause lung cancer or/and damage to the respiratory system.
Is Arthrobacter aerobic or anaerobic?
obligate aerobic bacteria
Members of the genus Arthrobacter are usually regarded as obligate aerobic bacteria. The anaerobic growth and energy metabolism of two Arthrobacter species were investigated.
Is Arthrobacter motile?
Arthrobacter agilis Spheres (0.8–1.2 μm in diameter) occur in pairs and tetrads. The dark rose-red pigment is water-insoluble. The species is motile by means of one to three flagella, though non-motile strains can occur.
What are differences between the bacterial species Arthrobacter Globiformis and Arthrobacter Nicotianae?
The two major ‘species groups’A. globiformis/Arthrobacter citreus and Arthrobacter nicotianae differ in their peptidoglycan structure, teichoic acid content and lipid composition [4].
Is Arthrobacter oxidase positive or negative?
The type strain of A. albus is CF43 (DSM 13068). The genus Arthrobacter includes catalase-positive coryneform bacteria with an oxidative metabolism, the cell wall of which contains l-lysine as the diamino acid and cellular fatty acids of the branched type (6).
Who discovered arthrobacter?
American bacteriologists, Harold J. Conn and Isabel Dimmick, introduced the genus name Arthrobacter in 1947 reviving it from a hypothetical name that was proposed by German botanist, Alfred Fischer. Conn and Dimmick classified three species in the genus Arthrobacter, and one of the species was A.
Is arthrobacter motile?
What disease is caused by Arthrobacter?
Arthrobacter species was reported as a cause of well-documented human disease only on 5 other occasions: 2 cases of bacteremia, 1 case of postoperative endophthalmitis, 1 case of Whipple disease—like syndrome, and 1 case of phlebitis (table 1).
Is arthrobacter aerobic or anaerobic?
What is Arthrobacter spp?
M. Gobbetti, C.G. Rizzello, in Encyclopedia of Food Microbiology (Second Edition), 2014 Arthrobacter is a genus of obligate aerobes bacteria characterized by a rod–coccus growth cycle. Arthrobacter spp. commonly are found in soils, aerial surface of plants, and wastewater sediments; they do not form endospores and are highly proteolytic.
What are the commercial applications of Arthrobacter species?
Various Arthrobacter species have been investigated for other commercial applications. A. crystallopoietes and A. chlorophenolicus have been shown to reduce hexavalent chromium and 4-chlorophenol levels in contaminated soil, suggesting they may be useful for bioremediation.
How many species are there in the genus Arthrobacter?
The genus Arthrobacter is a heterogeneous conglomeration of approx. 80 species and may require dissection into several novel genera.
What is the DNA G + C content of Arthrobacter?
Arthrobacter shows a rod–coccus growth cycle, aerobic metabolism, and little or no acid production from glucose. Lysine is present in the peptidoglycan and it has a DNA G + C content of 59–66 mol.% ( Jones and Keddie, 2006 ).
