The bacteria belonging to the families of the Thiobacteriaceae, Beggiatoaceae and Achromatiaceae are commonly called the colourless sulfur bacteria. While their ability to oxidize reduced inorganic sulfur compounds has clearly been established, it is still not known whether all these organisms can derive metabolically useful energy from these oxidations. During the last decades research has mainly focussed on the genus Thiobacillus. Bacteria belonging to this genus can oxidize a variety of…

Colorless Sulfur Bacteria
This chapter describes the scientific stages taken to reach this point, reviews the reorganization that has been necessary among the colorless sulfur bacteria, and considers the fact that while the metabolic trait is of less taxonomic significance than previously believed, this grouping is important ecologically and should be retained.
The Genera Thiobacillus and Thiomicrospira
A common feature of the members of the genera Thiobacillus and Thiomicrospira is their ability to oxidize inorganic sulfur compounds for the generation of energy. Almost all can grow autotrophically,
Growth physiology and competitive interaction of obligately chemolithoautotrophic, haloalkaliphilic, sulfur-oxidizing bacteria from soda lakes
Different growth characteristics and salt resistance appear to determine the outcome of the enrichment cultures from different soda lakes: Thioalkalimicrobium dominated in the enrichments with freshly obtained samples from diluted soda lakes at low-medium salinity, while ThIOalkalivibrio was the predominant organism in enrichments from aged samples and at hypersaline conditions.
Colorless Sulfur Bacteria , Beggiatoa spp . and Thiovulum spp . , in 02 and H 2 S Microgradients
pm. An unstirred boundary layer in the water surrounding the mats and veils prevented microturbulent or convective mixing of 02 and H2S. The two substrates reached the bacteria only by molecular
CO metabolism of carboxydothermus hydrogenoformans and archaeoglobus fulgidus
Microbial CO metabolism was studied in detail with the ultimate aim to assess the feasibility of a biotechnological process that could replace the existing water gas shift technology in the production of a fuel cell grade hydrogen gas from synthesis gas and show that many electron acceptors can be reduced by a wide variety of micro organisms with CO as electron donor.
Effect of nutrients and elemental sulfur particle size on elemental sulfur oxidation and the growth of Thiobacillus thiooxidans
Two laboratory incubation experiments with a high S sorbing basaltic soil from Walcha, New South Wales, are reported here and the S oxidation rates recorded in these experiments were compared with those predicted by an S oxidation model and found to be in close agreement.

Biological sulphide oxidation in a fed‐batch reactor
This study shows that, in a sulphide‐oxidizing bioreactor with a mixed culture of Thiobacilli, the formation of sulphur and sulphate as end‐products from the oxidation of sulphide can be


Biochemical Basis of Obligate Autotrophy in Blue-Green Algae and Thiobacilli
An interpretation of obligate autotrophy in both physiological and evolutionary terms has been developed and patterns suggest that the tricarboxylic acid cycle is blocked at the level of alpha-ketoglutarate oxidation.
Enzymes of Carbohydrate Metabolism in Thiobacillus species
The data suggest that NAD-linked isocitrate dehydrogenase activity in thiobacilli is involved in biosynthetic reactions, and is apparently the major route of glucose dissimilation in this organism.
Sulfolobus: A new genus of sulfur-oxidizing bacteria living at low pH and high temperature
Sulfolobus apparently has no close relationship with any previously described bacteria, either heterotrophic or autrotrophic, and may be an important geochemical agent in the production of sulfuric acid from sulfur in high temperature hydrothermal systems.
Studies on thiobacillus denitrificans
SummaryExperiments with T. denitrificans have shown that this bacterium cannot develop in media devoid of ammonium salts, and that iron is required for growth. Pure cultures have been isolated by
Activity of sulphur-oxidizing microorganisms in some Australian soils
The percentage oxidation of sulphur and the activity of Thiobacillus thiooxidans in a red-brown earth and a chernozem were followed at monthly intervals over a period of a year, but no obvious

Clinical cultures of Thiobacillus neapolitanus strain C assimilate 14C-labelled acetate and aspartate indicate glutamate synthesis from α-ketoglutarate formed by reactions of the tricarboxylic acid cycle, and functions as a glutamate-synthesising system using oxaloacetate derived solely from carbon dioxide fixation.
Sulfide and thiosulfate-oxidizing bacteria in anoxic marine basins
Comparison of the metabolic capabilities of the isolates during growth in sulfide and thiosulfate media with chemical parameters measured in the Black Sea and Cariaco Trench waters suggests that the biological oxidation of thios sulfurate is the rate-limiting step in the oxidative turnover of sulfur compounds in the basins.
Regulation of Glucose Metabolism in Thiobacillus intermedius
It is concluded that the Entner-Doudoroff pathway performs an energetic role in glucose metabolism by T. intermedius with the pentose shunt and Embden-Meyerhof pathways functioning mainly in biosynthesis.
