Classification

Domain: bacteria; Phylum: Pseudomonadota; Class: Gammaproteobacteria; Order: Thiotrichales; family: Beggiatoaceae


Description and Significance

Description: Strains of colorless, filamentous, gliding bacteria, visible to the naked eye.

Size: Ranging from about 3.0 to 5.0 μm in diameter

Habitat: Lives at the oxic/anoxic interface of aquatic habitats in high concentrations of sulfide reaching toxic levels. these environments include cold seeps, sulfur springs, sewage contaminated water, mud layers of lakes,near deep hydrothermal vents and many others.

Importance: Due to its ability to detoxify sulfide, this microbe plays a huge role in the sulfur cycle of coastal environments.

Genome Structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?


Cell Structure and Metabolism

Interesting features of cell structure?: The cell wall consists of five discrete layers external to the cytoplasmic membrane, the surface layer contains linear arranged longitudinal fibrils ranging from 10 to 12 nm in diameter, thin sections of sulfur inclusions contain 12 to 14 nm thick pentalaminar envelope.

metabolism: the metabolism of this species of Beggiatoa is facultative Methylotrophs within a fresh water strain.

How does it gain energy?:

what important molecules does it produce?:

Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.

If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
