Carbohydrate Degradation Pathways in Thiobacillus A2 Grown on Various Sugars
A detailed radiorespirometric and enzymological analysis was made of the wild-type and GFI strains of Thiobacillus A2 grown on numerous sugars. The wild-type used the EmbdenMeyerhof, Entner-Doudoroff and pentose phosphate pathways for glucose oxidation only after culture on glucose. The fast-growing strain GFI used all three pathways after growth on glucose, maltose or fructose. The wild-type g...
متن کاملColonial variation and fimbriation of Actinobacillus actinomycetemcomitans.
Three colonial variants of Actinobacillus actinomycetemcomitans, which formed transparent rough (TR)-, transparent smooth (TS)-, and opaque smooth (OS)-surfaced colonies, were described in relation to their fimbriation. TR- and TS-cells were adhesive to agar and glass surfaces but not the OS-cells. The examination by electron microscopy revealed that TR-cells were highly fimbriated but not TS- ...
متن کاملThiosulphate Oxidation in Thiobacillus
bacterium Thiobacillus X. A fifth fraction (acidic fraction) contained two additional cytochrome components with x bands at 550 and 557 msi respectively in the reduced state. 2. All the cytochromes appear to be ofthe c type, are labile to heat and acid and do not combine with carbon monoxide. They are auto-oxidizable to varying degrees. 3. Cytochromes 550 (1) and 557 (1) are basic, and are adso...
متن کاملImproved Assay for Rhodanese in Thiobacillus spp.
Rhodanese (thiosulfate:cyanide sulfurtransferase; EC 2.8.1.1) catalyzes the conversion of thiosulfate and cyanide to thiocyanate and sulfite. Conventional rhodanese assays colorimetrically measure the formation of one or the other of the products. These assays suffer from the fact that there is significant nonbiological formation of these products in addition to the enzymatically catalyzed reac...
متن کاملSulfite oxidase activity in Thiobacillus novellus.
Thiobacillus novellus shows a maximum induction of sulfite oxidase activity and a maximum growth rate as a result of supplementing the autotrophic growth medium with 4.0 microM ammonium molybdate. Cells grown in the presence of molybdate showed approximately 10-fold increases in the amount of enzyme-associated molybdenum and in the sulfite-to-cytochrome c and sulfite-to-ferricyanide reductase a...
