The colorless cells of Beggiatoa are in free filaments, 1-30x4-20μm in size. The bacteria move in a sliding fashion. Gram stain was negative.
Beggiatoa is nourished by respiratory metabolism, in which molecular oxygen is used as the final electron acceptor. Some strains require the addition of organic growth factors to the medium. Cells contain sulfur particles when the organism is grown in the presence of H2S. Intracellular poly-β-hydroxybutyric acid granules and metachromatic granules may be present.
Beggiatoa is aerobic to micro-aerobic. There are known seawater and freshwater types.
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 Beggiatoa strain culture services. This service can help you obtain cultures of Beggiatoa 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.

The filaments of Beggiatoa alba are 2.5-5.0 microns wide. Except that the cells are square just after division, they are flaky at other times. Sheet cells are 3-9 microns long.
The filaments of Beggiatoa arachnoidea are 5-14 microns wide; cell fragments are 5-7 microns long.
The filaments of Beggiatoa gigantea are 26-55μm wide and the cell fragments are 5-13μm long.
The filaments of Beggiatoa leptomitiformis are 1-2μm wide and the cell fragments are 4-8μm long.
The filament width of Beggiatoa minima is equal to or less than 1 micron. Cell fragments are 5-13μm long.
Filaments of Beggiatoa mirabilis are 15-21μm wide; cell fragments are 5-13μm long.
The culture of Beggiatoa requires specific formulations of growth media for use in cloning, plasmid DNA preparation, and protein expression.
