Fig. 2From: Permanent draft genome of Thiobacillus thioparus DSM 505T, an obligately chemolithoautotrophic member of the Betaproteobacteria Transmission electron micrographs of T. thioparus DSM 505T cells obtained from a thiosulfate-limited chemostat (20 mM, D = 0.07 h−1) visualized in a JEOL JEM-1400Plus transmission electron microscope, operating at 120 kV. a Negatively stained cells. Cells were applied to Formvar® and carbon coated copper grid before washing with saline and staining in 50 mM uranyl acetate for 5 mins and washing again. b Sectioned cells showing the presence of an electron dense polyphosphate (‘volutin’) granule and numerous polyhedral carboxysomes that are paler in comparisonBack to article page
