Effects of 60Co gamma-rays, ultraviolet light, and mitomycin C on Halobacterium salinarium and Thiobacillus intermedius.
Lethal effects of 60Co gamma-rays, UV light, and mitomycin C on two kinds of bacteria, Halobacterium salinarium which grows in highly concentrated salt media and Thiobacillus intermedius which requires reduced sulfur compounds, were studied and compared with those on Escherichia coli B/r. D37 values for H. salinarium, T. intermedius and E. coli B/r were 393, 150, and 92 Gy, respectively, by exp...
متن کاملHalophilic enzymes in cell-free extracts of Halobacterium salinarium.
Cells of the obligately halophilic bacterium Halobacterium salinarium have been shown to contain high concentrations of sodium and potassium chloride (Christian and Ingram, J. Gen. Microbiol. 20:27, 1959; Christian and Waltho, Biochim. Biophys. Acta 65:506, 1962). Enzymes extracted from this organism require up to 25% NaCl for optimal activity (Baxter and Gibbons, Can. J. Microbiol. 2:599, 1956...
متن کاملArginine deiminase from Halobacterium salinarium. Purification and properties.
Arginine deiminase from the extreme halophilic archaebacterium Halobacterium salinarium was purified to homogeneity in a four-step procedure with a 310-fold enrichment. The enzyme consists of two identical subunits of 55 kDa; its native molecular mass is 105 kDa. The pI of 4.7 indicates that acidic nature of the protein, which is evidenced by its amino acid composition, which shows an excess of...
متن کاملArginine metabolism in Halobacterium salinarium, an obligately halophilic bacterium.
Dundas, Ian E. D. (University of Illinois, Urbana), and H. Orin Halvorson. Arginine metabolism in Halobacterium salinarium, an obligately halophilic bacterium. J. Bacteriol. 91:113-119. 1966.-Arginine was shown to be essential for growth of Halobacterium salinarium strain 1 in a chemically defined medium. Citrulline was the only compound which could substitute for arginine without affecting gro...
متن کاملFermentative arginine degradation in Halobacterium salinarium (formerly Halobacterium halobium): genes, gene products, and transcripts of the arcRACB gene cluster.
Fermentative growth via the arginine deiminase pathway is mediated by the enzymes arginine deiminase, carbamate kinase, and catabolic ornithine transcarbamylase and by a membrane-bound arginine-ornithine antiporter. Recently we reported the characterization of catabolic ornithine transcarbamylase and the corresponding gene, arcB, from Halobacterium salinarium (formerly Halobacterium halobium). ...
