Murein Structure of Three Different Species of Chemolithotrophic Sulfur Bacteria: Thiobacillus tepidarius, Thiobacillus neapolitanus and Thiobacillus versutus
The genus Thiobacillus is an extremely heterogeneous group of bacteria. The only criterion for placing all the species in a single genus is that they all obtain energy for autotrophic growth from the oxidation of inorganic sulfur substrates. Some species are obligately chemolitotrophic and autotrophic (e.g. Thiobacillus neapolitanus and Thiobacillus tepidarius) whereas others are facultatively autotrophic and capable of heterotrophic growth using a wide range of organic substrates (e.g. Thiobacillus versutus). The facultative species are frequently indistinguishable from some of the bacteria grouped as Pseudomonas, except for their capacity for growth with reduced sulfur compounds (Kelly and Harrison, 1989). It has been suggested that the facultative or mixotrophic Thiobacillus species be reassigned to the appropriate genera of chemoorganotrophic bacteria (Friedrich and Mitrenga, 1981).
