Toxothrix Cultivation

In filaments up to 400μm long, Toxothrix cells are colorless cylinders with a size of 0.5-0.75X3-6μm. There is often a dense area at either end of the cell, and no Gram staining reaction has been reported. The filaments of the bacteria are often "U" shaped. The filament rotates as it moves slowly forward. When operating, the "U"-shaped round part is in front, and the two lines are dragged. The latter can secrete a mucous substance from several places and settle into two twisted traces (like railway tracks), each about 0.2 micrometers wide. As the two arms of the "U" shape move from one side to the other, and between the tracks due to the fluctuation of the middle part of the "U" shape, which rises and then falls, a fan-shaped structure is formed along the sides of the track. Iron oxide can be precipitated on the mucus line, and the mucus line is brown and easy to break, and its diameter is 2.5 microns. Toxothrix has not been purified so far, it is heterotrophic and psychrophilic. It can be stored for a long time at 5°-10°C. Filaments are very brittle during laboratory assays, and abrupt rupture is observed within a short period of time. It grows anchored to the surface and grows best under conditions of reduced oxygen tension and neutrality (pH 6.5-7.2). Toxothrix was originally discovered in a reservoir near the biological station on the Dnieper River in Russia, and is widely distributed in ferrous cold springs, swamps, ponds and lakes.
