“…Prislc by a decrease in the amount of elementary sulphur and a corresponding rise in sulphate concentration. This confirmed the suggestion of Starkey (1935 a) that the decrease in pH value which follows the disappearance of thiosulphate is due to oxidation of sulphur. The continued viability of the culture for a t least 18 days after the disappearance of the thiosulphate, when elementary sulphur was the only available sulphur source, suggests that this conversion of elementary sulphur to sulphuric acid is biological.…”

SUMMARY ; Cultures of Thiobacillus thiooxidans, Th. thioparus, Th. novellus, Thiobacillus B (Waksman, 1922a), strains 'T' and 'K' (Trautwein, 1921) and Th. concretivorus, Thiobacillus X and the 'M' strains, organisms isolated from concrete (Parker, 1945(Parker, , 1947, were examined to elucidate the mode of oxidation and to establish the identity of the organisms recently isolated from corroded concrete.Thiosulphate was oxidized by all these bacteria. Th. thiooxidans, Th. concretivorus and Thiobacillus X first converted it to tetrathionate and sulphate and then oxidized the tetrathionate to sulphate and free sulphuric acid. Thiobacillus X differed from the other two in that, owing to a lesser acid tolerance, some tetrathionate was found in the final products of oxidation. Th. thioparus converted thiosulphate to sulphate and sulphur, followed by partial oxidation of the sulphur to sulphuric acid. Th. novellus produced sulphate and sulphuric acid. Thiobacillus B, the 'T' and ' K ' strains and the ' M ' strains formed sulphate and tetrathionate with temporary increase in pH value ; only Thiobacillus X oxidized tetrathionate, yielding sulphate and sulphuric acid.Elementary sulphur was oxidized by Th. thiooxidans, Th. concretivorus, Thiobacillus X and Th. thioparus; the rates of oxidation decreased in that order, and the only product was sulphuric acid. Hydrogen sulphide was oxidized only at low concentrations and only by Th. concretivorus and Thiobacillus X ; sulphuric acid was the end-product, and elementary sulphur may have been an intermediate. ThiobacilZus X differed from Th. thiooxidans in pH range for growth and fromTh. thioparus in its method of oxidation of thiosulphate, tetrathionate and H,S. It appeared to fit earlier descriptions of Th. thioparus by Nathansohn (1902) and Beijerinck (1904) more closely than the strain described as Th. thioparus by Starkey ( 1 9 3 4~) .

“…The exclusion of T. trautweinii from the genus was deemed reasonable on the basis of the quinone system and cellular fatty acid composition, especially the presence of the hydroxy fatty acid, as well as physiological characteristics (Starkey, 1935;Huchinson et al, 1965Huchinson et al, , 1969. Thiobacillus trautweinii THI 081 and THI 082 were recognized as a strain of Pseudomonas and a strain of Alcaligenes, respectively, in the catalogue of strains of the National Collection of Industrial Bacteria (Bousfield & Graham, 1975).…”

Facultatively chemolithotrophic thiobacilli, Thiobacillus perometabolis THI 022, Thiobacillus sp. A2, Thiobacillus novellus, Thiobacillus organoparus and Thiobacillus acidophilus, had ubiquinones with 10 isoprene units (Q-10) (group I). These species also had [octadecenoic acid (18 : 1) + cyclopropane acid of CI9 (19, , , )] as major non-hydroxylated fatty acids. The organisms, except T. novellus, contained 3-hydroxydecanoic acid (3-OH 10 : 0) or 3-hydroxytetradecanoic acid (3-OH 14 : 0) as hydroxy fatty acids. DNA base compositions of these species were 63 to 68 mol% G + C. Other facultatively chemolithotrophic thiobacilli, including T. perometabolis THI 023, Thiobacillus delicatus and Thiobacillus intermedius with or without [ 18 : 1 + 19, , , ] as major non-hydroxylated fatty acids. The species of group I11 contained 3-OH 12:O and some had 3-OH 10:0 when grown at neutral pH and 3-OH 14 :O in acidophilic conditions. DNA base compositions of these organisms ranged from 5 1 to 64 mol% G + C. Chemotaxonomic characteristics would seem to be useful for the identification and the classification of thiobacilli.

“…The most prominent feature of S. novella is its ability to grow as a facultative chemolithoautotroph [3], a heterotroph [4], or methylotroph [1,5]. Cultures of strain ATCC 8093T were first isolated from soil samples taken from agricultural land in New Jersey by Robert L. Starkey in the early 1930s [6,7] and deposited in the American Type Culture Collection (ATCC) under the basonym Thiobacillus novellus [3,8]. The bacterium was referred to as the 'new' Thiobacillus as it was the first facultatively chemolithoautotrophic sulfur oxidizer to be isolated.…”
