| the uptake and assimilation of sulphate by thiobacillus ferrooxidans. | sulphate was rapidly bound by cell suspensions of thiobacillus ferrooxidans. the binding was depressed by tetrathionate but was unaffected by group vi anions, cysteine or methionine. increasing uptake of sulphate was observed in cell suspensions incubated in the presence of ferrous iron. the bulk of 35s-sulphate was removed from the organisms by washing with dilute sulphuric acid and the remaining label was incorporated into cold trichloroacetic acid-soluble compounds. 35s-labelled adenosine 5'- ... | 1975 | 1200736 |
| [the effect physical factors and proteolytic enzymes on actinomycete mycelium and spores]. | the influence of enzymes (lyzozyme, trypsin, papain) and physical factors (hydrostatic pressure, mechanical sand grinding, extrusion in the frozen state, ultrasonic treatment) on the spores and mycelium of actinomycetes actinomyces streptomycini b-6 and thiobacillus vulgaris 2681 was studied. actinomycete spores proved to be stable to trypsin and papain. lyzozyme induced an almost complete disruption of the mycelium. the influence of hydrostatic pressure and lyzozyme on spores was the least effe ... | 1975 | 1208433 |

| degradation of oil shale by sulfur-oxidizing bacteria. | approximately 40% of oil shale can be solubilized by the action of sulfur-oxidizing bacteria. thiobacillus thiooxidans and thiobacillus concretivorous are equally effective in solubilization. continuous leaching experiments show that this process can be completed within 14 days. the growth of thiobacillus and the production of acid were measured under several conditions. almost all of the camg(co(3))(2) was removed by this process, leaving a complex of silica and kerogen that could be burned as ... | 1974 | 4370628 |

| direct method for continuous determination of iron oxidation by autotrophic bacteria. | a method for direct, continuous determination of ferric ions produced in autotrophic iron oxidation, which depends upon the measurement of ferric ion absorbance at 304 nm, is described. the use of initial rates is shown to compensate for such changes in extinction during oxidation, which are due to dependence of the extinction coefficient on the ratio of complexing anions to ferric ions. a graphical method and a computer method are given for determination of absolute ferric ion concentration, at ... | 1974 | 4441066 |

| heterotrophic nature of the cell-free protein-synthesizing system from the strict chemolithotroph, thiobacillus thiooxidans. | a cell-free protein-synthesizing system prepared from the strict chemolithotroph, thiobacillus thiooxidans, was similar to that of heterotrophs. the poly-u directed system had a temperature optimum of 37 c, but in the presence of spermidine (3 mm) the optimum shifted to 45 c. although growth of the chemolithotroph occurs only in acid conditions, the ph optimum for the cell-free system was ph 7.2. the endogenous-directed activity in the presence or absence of spermidine was maximal at ph 7.8. spe ... | 1974 | 4590488 |

| thiosulfate- and sulfide-dependent pyridine nucleotide reduction and gluconeogenesis in intact thiobacillus neapolitanus. | nicotinamide adenine dinucleotide phosphate (reduced form) is formed more rapidly after the addition of thiosulfate to suspensions of intact thiobacillus neapolitanus in the absence of co(2) than nicotinamide adenine dinucleotide (reduced form). measurement of acid-stable metabolites shows this phenomenon to be the result of rapid reoxidation of nicotinamide adenine dinucleotide (reduced form) by 3-phosphoglyceric acid and other oxidized intermediates, which are converted to triose and hexose ph ... | 1973 | 4145196 |

| a salt-inhibited cytochrome c reductase obtained from the moderately halophilic bacterium, micrococcus halodenitrificans. | a membrane-bound cytochrome c reductase from micrococcus halodenitrificans was inhibited by nacl at concentrations as low as 0.05 m. the inhibition was competitive with respect to cytochrome c and noncompetitive with respect to reduced nicotinamide adenine dinucleotide. thus the effect of nacl was to increase the apparent k(m) of the enzyme for cytochrome c and not to inhibit the intrinsic activity of the enzyme. | 1972 | 4342818 |
| growth of obligate autotrophic bacteria on glucose in a continuous flow-through apparatus. | nitrosomonas europaea, nitrobacter agilis, thiobacillus denitrificans, t. neapolitanus, and t. thioparus (all obligate autotrophic bacteria) have been grown in dialysis culture, on glucose salts media, in the absence of their specific inorganic energy source. metabolic products for n. agilis grown on nitrite salts medium were identified as keto acids. pyruvic acid inhibited this organism at 5 x 10(-5)m. keto acids were not inhibitory for the thiobacilli grown on thiosulfate medium. however, when ... | 1972 | 4551747 |

| effect of cultural conditions on the fatty acid composition of thiobacillus novellus. | the fatty acid content of thiobacillus novellus was determined under various cultural conditions. four fatty acids, c(16:0), c(18:0), c(18:1), and a c(19) cyclopropane acid (c(19:cyc)), generally accounted for 90 to 99% of the total acids. phosphate concentration, temperature, culture agitation, and the presence of branch-chain precursors had no significant effect on cellular fatty acids. autotrophically grown cells contained more saturated c(16) and c(18) acids than did heterotrophic ones, and ... | 1972 | 5086663 |

| chalcocite oxidation and coupled carbon dioxide fixation by thiobacillus ferrooxidans. | the reaction of cell suspensions of thiobacillus ferrooxidans with pulverized chalcocite (cu(2)s) in a warburg manometric apparatus resulted in oxygen uptake accompanied by increased solubilization of copper and fixation of carbon dioxide. since the only detectable oxidized products were cupric ions and the more oxidized form of the sulfide mineral, that is, digenite or covellite, the apparent source of energy for the carbon dioxide fixation was provided by the oxidation of the cuprous copper of ... | 1972 | 17797392 |

| utilization of glucose and the effect of organic compounds on the chemolithotroph thiobacillus ferrooxidans. | the utilization of glucose by the chemolithotroph thiobacillus ferrooxidans results in a repression of the ability to oxidize iron, the substrate for autotrophic growth. an assay with resting cells was used to measure iron oxidation rates. concomitant with the decreased iron oxidation rates, the enzyme responsible for carbon dioxide fixation, ribulose diphosphate (rudp) carboxylase, was also repressed. maximum iron oxidation rates precede peak rudp carboxylase levels, consistent with the role of ... | 1971 | 5122808 |
