The protonema of Vitreoscilla are colorless and 1.2-2x3-70 microns in size. The colony edges of Vitreoscilla consist of distinct cylindrical or barrel cells. The cells of Vitreoscilla reproduce by breaking and moving in a sliding fashion. Gram staining of the bacteria was negative.
Vitreoscilla's organic energy nutrition is presumed to be only respiratory metabolism. Previous studies have found that the bacteria cannot hydrolyze proteins. This bacterium has only been reported to grow on complex media and its minimum nutritional requirements are not known. In addition, Vitreoscilla does not form intracellular sulfur particles from hydrogen sulfide.
Bacteria exist widely in nature, but most of them are mixed together, which is very difficult to study in isolation. Therefore, bacterial researchers need to isolate and explore suitable culture conditions before conducting individual bacterial species research. But this process is complicated and time-consuming. Creative Biogene provides customizable Vitreoscilla strain culture services. This service can help you obtain cultures of Vitreoscilla for subsequent scientific research. This service allows you to skip the complicated and tedious groping of culture conditions, which helps to speed up research on this strain.
In the protonema, the cells of Vitreoscilla beggiatoides are cylindrical with blunt ends, and can move in a sliding manner at a slow speed (approximately 2 μm/s).
Protonema of Vitreoscilla moniliformis in chains. The size of protonema is 2.2-3.0x30-150 μm. Each protonema may be sausage-shaped, up to 3.0 μm in diameter. The bacteria can move in a sliding manner, and can move in a sliding manner at a slow speed (approximately 2 microns/minute).

The protonema of Vitreoscilla stercoraria are 1.2-1.5 x 100 μm in size and often have irregular inflections. The cells within the protonema are sausage-shaped and are 1.2-1.5x1.2-12 microns in size. Sliding motion can be performed, and the motion is slower, about 2 microns per minute.
When Vitreoscilla filiformis was on agar media, its colonies were arc-shaped or annular like some strains of oscillloria.
The protonema of Vitreoscilla catenula are cylindrical and 1.5-2.0 microns wide. The barrel cells involved in the formation of protonema are 3-6 μm long and have constricted parts between cells.
The culture of Vitreoscilla requires specific formulations of growth media for use in cloning, plasmid DNA preparation, and protein expression.
