Abstract
Rhodovulum sulfidophilum is a purple bacteria.Hansen, ToA, and H. Veldkamp. "Rhodopseudomonas sulfidophila, nov. spec., a new species of the purple nonsulfur bacteria." Archiv für Mikrobiologie 92.1 (1973): 45-58. The cells are rod-shaped, 0.6 to 0.9 μ wide and 0.9 to 2.0 μ long, and motile by means of polar flagella. Cell division occurs by binary fission. Its pigments consist of bacteriochlorophyll a and of carotenoids, most probably of the spheroidene group. The new species needs 2.5% (w/v) sodium chloride for optimal growth. The bacteria has a high sulfide tolerance. Sulfide and thiosulfate are oxidized to sulfate without an intermediate accumulation of elemental sulfur. It can either grow photoautotrophically or photoheterotrophically.
Genetic engineering to produce spider silk
, a Japanese research team from RIKΞN reported that they succeeded in using a genetically altered variant of R. sulfidophilum to produce spidroins, the main proteins in spider silk.
