anaerobic production of thiobacillus denitrificans for the enzyme rhodanese.a method for the anaerobic growth of thiobacillus denitrificans in a 140-liter (total capacity) stainless-steel culture vessel is described. as a result of controlling the ph value of cultures, and of ensuring that certain essential nutrients were in excess, cell yields approaching 700 mg (dry weight) per liter were obtained. these were over threefold higher than the best yields hitherto reported. the average rhodanese content of the cells from four cultures was 176,000 units per gram (dry weigh ...196616349709

biochemical basis of obligate autotrophy in blue-green algae and thiobacilli.differential rates of incorporation of sugars, organic acids, and amino acids during autotrophic growth of several blue-green algae and thiobacilli have been determined. in obligate autotrophs (both blue-green algae and thiobacilli), exogenously furnished organic compounds make a very small contribution to cellular carbon; acetate, the most readily incorporated compound of those studied, contributes about 10% of newly synthesized cellular carbon. in thiobacillus intermedius, a facultative chemoa ...19674963789

keto acids as growth-limiting factors in autotrophic growth of thiobacillus thiooxidans.when the strictly autotrophic bacterium thiobacillus thiooxidans was grown on sulfur, keto acids accumulated in the medium until they reached an inhibitory level at which growth ceased. much greater growth was possible if these substances were continually dialyzed out of the medium.19676020564
yield coefficients of thiobacillus neapolitanus in continuous culture.thiobacillus neapolitanus, when grown in continuous culture with thiosulfate limiting growth, possessed an apparent maximal molar growth yield of 8.0 g (dry weight) per mole of thiosulfate. the substrate requirement for energy of maintenance was the highest yet reported, amounting to 21.8 mmoles of thiosulfate per g per hr. the molar growth yield, corrected for this maintenance energy requirement, was 13.9 g (dry weight) per mole of thiosulfate. it was concluded that substrate-level phosphorylat ...19676025430

catabolite repression in the facultative chemoautotroph thiobacillus novellus.several fermentable carbon sources were found to give rise to catabolite repression of all enzymes implicated in thiosulfate oxidation in the facultative chemoautotroph, thiobacillus novellus. glucose was found to elicit a strong repression. glycerol, lactate, lactose, ribose, and pyruvate caused marked repression. in all cases, the repression could be relieved only by returning the cells to a medium devoid of such fermentable substrates. on the other hand, carbon compounds (amino acids and orga ...19676057804

effect of adenosine monophosphate, adenosine diphosphate, and reduced nicotinamide adenine dinucleotide on adenosine triphosphate-dependent carbon dioxide fixation in the autotroph thiobacillus neapolitanus.the observation that adenosine triphosphate (atp)-dependent co(2) fixation in extracts of chemosynthetic and photosynthetic autotrophs may be regulated in part by adenosine monophosphate (amp) was extended to the strict autotroph thiobacillus neapolitanus (x). in addition, this report presents data which include adenosine diphosphate (adp) in the regulatory role. when the primary co(2) acceptor, ribose-5-phosphate, was replaced by ribulose-1,5-diphosphate, no inhibition of co(2) fixation occurre ...19674292312
evidence for the calvin cycle and hexose monophosphate pathway in thiobacillus ferrooxidans.the enzymes of the calvin reductive pentose phosphate cycle and the hexose monophosphate pathway have been demonstrated in cell-free extracts of thiobacillus ferrooxidans. this, together with analyses of the products of co(2) fixation in cell-free systems, suggests that these pathways are operative in whole cells of this microorganism. nevertheless, the amount of co(2) fixed in these cell-free systems was limited by the type and amount of compound added as substrate. the inability of cell extrac ...19674293079

inhibition of oxygen utilization and destruction of ubiquinone by ultraviolet irradiation of thiobacillus thiooxidans.ultraviolet (uv) irradiation inhibited sulfur oxidation by cells of thiobacillus thiooxidans. sulfur-oxidizing activity decreased as the exposure time to uv light increased. a loss of the ability of cells of fix co(2) paralleled the loss of sulfur-oxidizing activity. uv light photoinactivated ubiquinone purified from t. thiooxidans. the same percentage of sulfur-oxidizing activity and ubiquinone was destroyed after 15 min of uv exposure. both the photoinactivation of sulfur oxidation and ubiquin ...19685636812

acetate assimilation by nitrobacter agilis in relation to its "obligate autotrophy".acetate (1 to 10 mm) had no effect on the rate of nitrite oxidation or exponential growth by nitrobacter agilis. however, acetate-1-(14)c and -2-(14)c were both assimilated by growing cultures, and acetate carbon contributed 33 to 39% of newly synthesized cell carbon. carbon from acetate was incorporated into all of the major cell constituents, including most of the amino acids of cell protein and poly-beta-hydroxybutyrate (phb). cultures grown in the presence of acetate showed a significant inc ...19685643062
phospholipids of the thiobacilli.phosphatidyl glycerol, disphosphatidyl glycerol, and phosphatidyl ethanolamine were found in all of the thiobacillus species studied. t. thioparus possessed only these phospholipids. t. intermedius, t. neapolitanus, and t. thiooxidans contained phosphatidyl-n-monomethylethanolamine, and t. novellus lipids contained phosphatidyl-n-monomethylethanolamine, phosphatidyl-n-n-dimethylethanolamine, and phosphatidyl choline, in addition to the three phospholipids common to all of the thiobacilli. methio ...19685669895

evidence for two species of glutamate dehydrogenases in thiobacillus novellus.when grown autotrophically in a thiosulfate-mineral salts medium, cells of the facultative chemoautotrophic bacterium, thiobacillus novellus, produced two distinct glutamate dehydrogenases, one specific for nicotinamide adenine dinucleotide phosphate (nadp) and the other specific for nicotinamide adenine dinucleotide (nad). when glutamate was supplied exogenously as the sole carbon source, the nad-specific glutamate dehydrogenase was fully induced. lower levels of the enzyme were found in bacter ...19684384066
