What does arthrobacter Globiformis do?
globiformis provides reliable source of nitrogen that plants need to grow. A. globiformis can also reduce pesticides as well as other harmful chemicals that are found in the soil. A lot of plants are not capable of growing in the presence of hexavalent and trivalent chromium, but A.
Where is Arthrobacter found?
soils
Abstract. 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.
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 gram negative?
Arthrobacter (from the Greek, “jointed small stick”) is a genus of bacteria that is commonly found in soil. All species in this genus are Gram-positive obligate aerobes that are rods during exponential growth and cocci in their stationary phase.
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.
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).
Is Arthrobacter harmful to humans?
Therefore, it is concluded that Arthrobacter globiformis strain ATCC 8010 is not harmful to human health or to the environment.
Is Arthrobacter motile?
Can Arthrobacter reduce nitrate?
The ability of Arthrobacter arilaitensis Y-10 for nitrogen removal from simulated wastewater was studied. Results showed that ammonium was the best inorganic nitrogen for strain Y-10’s cell growth, which could also promote nitrate reduction.
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).
Does arthrobacter hydrolyze starch?
Abstract. Properties of the extracellular amylase produced by the psychrotrophic bacterium, Arthrobacter psychrolactophilus, were determined for crude preparations and purified enzyme. The hydrolysis of soluble starch by concentrated crude preparations was found to be a nonlinear function of time at 30 and 40 °C.
Which are gram-positive bacteria?
Gram-positive cocci include Staphylococcus (catalase-positive), which grows clusters, and Streptococcus (catalase-negative), which grows in chains. The staphylococci further subdivide into coagulase-positive (S. aureus) and coagulase-negative (S. epidermidis and S.
