Mixotrophic Growth Under Micro-Oxic Conditions in the Purple Sulfur Bacterium "".

The microbial ecosystem of the meromictic Lake Cadagno (Ticino, Swiss Alps) has been studied intensively in order to understand structure and functioning of the anoxygenic phototrophic sulfur bacteria community living in the chemocline. It has been found that the purple sulfur bacterium "" strain Cad16, belonging to the Chromatiaceae, fixes around 26% of all bulk inorganic carbon in the chemocline, both during day and night. With this study, we elucidated for the first time the mode of carbon fixation of str.

Draft Genome Sequence of Chromatium okenii Isolated from the Stratified Alpine Lake Cadagno.

Blooms of purple sulfur bacteria (PSB) are important drivers of the global sulfur cycling oxidizing reduced sulfur in intertidal flats and stagnant water bodies. Since the discovery of PSB Chromatium okenii in 1838, it has been found that this species is characteristic of for stratified, sulfidic environments worldwide and its autotrophic metabolism has been studied in depth since. We describe here the first high-quality draft genome of a large-celled, phototrophic, γ-proteobacteria of the genus Chromatium isolated from the stratified alpine Lake Cadagno, C.

Complete genome sequence of "" sp. nov. strain Cad16, a photolithoautotrophic purple sulfur bacterium isolated from the alpine meromictic Lake Cadagno.

" sp. nov. strain Cad16 is a photoautotrophic purple sulfur bacterium belonging to the family of in the class of .

Cell biological characterization of the malaria vaccine candidate trophozoite exported protein 1.

In a genome-wide screen for alpha-helical coiled coil motifs aiming at structurally defined vaccine candidates we identified PFF0165c. This protein is exported in the trophozoite stage and was named accordingly Trophozoite exported protein 1 (Tex1). In an extensive preclinical evaluation of its coiled coil peptides Tex1 was identified as promising novel malaria vaccine candidate providing the rational for a comprehensive cell biological characterization of Tex1.
