Nutritional Control of Morphogenesis in Arthrobacter Crystallopietes.
Ensign, Jerald C. (University of Illinois, Urbana), and R. S. Wolfe. Nutritional control of morphogenesis in Arthrobacter crystallopoietes. J. Bacteriol. 87:924-932. 1964.-Arthrobacter crystallopoietes exhibits the cyclic, morphological variation which is a characteristic of this genus. A simple chemically defined medium was developed in which this organism is restricted to growth and division ...
متن کاملRegulation of cyclic AMP levels in Arthrobacter crystallopoietes and a morphogenetic mutant.
The extracellular levels of cyclic AMP (cAMP), cAMP phosphodiesterase activity, and adenylate cyclase activity were measured at various intervals during growth and morphogenesis of Arthrobacter crystallopoietes. There was a significant rise in the extracellular cAMP level at the onset of stationary phase, and this rise coincided with a decrease in intracellular cAMP. The phosphodiesterase activ...
متن کاملSurvival of Arthrobacter crystallopoietes during prolonged periods of extreme desiccation.
Cells of Arthrobacter crystallopoietes mixed in sand and air-dried have survived for up to 6 months after an initial period in which approximately half the cells lost their viability. Comparative survival curves have been obtained from inoculated sands maintained under CaSO(4) or P(2)O(5). Selections for more desiccation-resistant progeny capable of surviving the initial period were unsuccessfu...
متن کاملGene Knockout and Overexpression Analysis Revealed the Role of N-Acetylmuramidase in Autolysis of Lactobacillus delbrueckii subsp. bulgaricus Ljj-6
Autolysis of lactic acid bacteria (LAB) plays a vital role in dairy processing. During cheese making, autolysis of LAB affects cheese flavor development through release of intracellular enzymes and restricts the proliferation of cells in yogurt fermentation and probiotics production. In order to explore the mechanism of autolysis, the gene for the autolytic enzymes of L. bulgaricus, N-acetylmur...
متن کاملDraft Genome Sequence of Arthrobacter crystallopoietes Strain BAB-32, Revealing Genes for Bioremediation
Arthrobacter crystallopoietes strain BAB-32, a Gram-positive obligate aerobic actinobacterium having potential application in bioremediation and bioreduction of a few metals, was isolated from rhizosphere soil of Gandhinagar, Gujarat, India. The draft genome (4.3 Mb) of the strain revealed a few vital gene clusters involved in the metabolism of aromatic compounds, zinc, and sulfur.
