THIOTHRIX NIVEA

Class: Gamma Proteobacteria
Genus: Thiothrix
Species: Thiothrix nivea
Description: Thiothrix nivea is a 1-1.5 µm rod-shaped gram negative bacteria. When in the presence of sulfate or thiosulfate, sulfur granules are deposited in invaginations of the cytoplasmic membrane, external to the cytoplasm. Each cell has a tuft of fimbriae which anchors it to the cell beside it, and the colony to the substrate they may be growing on. Cells do not exhibit flagella. Cells grow and divide in a gliding motion enclosed within sheaths producing filamentous structures. When cells are clumped together, their division produces rosettes.
Synonyms: Beggiatoa nivea Rabenhorst 1865.
Source: T. nivea is found free living in sulfide containing flowing waters; such as sulfur springs, deep sea hydrothermal vents and is most well known for its populations in sewage waste water.3 T. nivea has been found to thrive within an optimal pH of 7.5 and temperatures ranging from 25-30 °C.Cells have been found to withstand temperatures of minimally 6-8 °C and maximally 32-34 °C.
